Ford Super Duty (1999-2016) :: 4r100 Shifts Great Until The Truck Warms Up
I had some more time to mess around with my truck. The 4r100 shifts great until the truck warms up. After about 10 to 15 minutes of driving it starts. With the gear selector in D and under acceleration it will shift at about 2k rpm's and will be in third gear by 25mph. If I climb to higher speeds it will only shift out of O/D when I get my foot into it. It will not downshift into any gears until I am almost completely stopped. It will downshift and hold gears great if I use the column to shift. I'm stumped. No CEL or flashing O/D light.
Things I have checked:
TPS
VSS
All connections to the transmission
Set tune back to stock
Transmission fluid & level
Will the transmission still store codes even if the O/D light has never flashed?
Ford Super Duty (1999-2016) :: 2011 F350 - Shifts Hard When Cold / Cool
I recently purchased a 2011 F-350 w/6.7 diesel. When I first start it & let it run say 30 seconds and take off it shifts fine from 1 to 2 but when it goes from 2-3 it hangs there a second and then finally shifts into 3rd hard. 3rd to 4th is ok but 4-5 again is a hard shift and from 5 to 6 is OK. It will do this for a while like through the neighborhood and down the road 10 miles then it is fine. Shifts beautifully when warmed up.
My local Ford dealer has a guy that is supposed to be very knowledgeable with Super Duty trucks. I have had it to him twice and he says this is normal. All shift hard until the transmission is up to operating temperature. Says the engine is very powerful and until everything is up to temperature this will happen. If so then it would be normal to let it sit and run for a while before you take off in the morning. I am getting ready to hook the truck up to my 33' camper and go on our first camping season with the trailer/truck combination and if I need to leave it sit and warm up I will.
Ford Super Duty (1999-2016) :: 2004 F250 - Trans Never Shifts From First Gear
I recently purchased a 04 f250 with the 6.0l powerstroke. I drove it for about 3 weeks now, Ive put my trailer behind it with small loads and just today tried to use the tow/haul button. When you go to pull out the tranny never shifts from first gear?? Its pulls and runs fine until you push the buttan and no shifting........

My daughter has this truck and I was driving it the other day I noticed it misfiring when the trans shifts down under a slight pull and/or going up hills. It looses power and speed when this happens but if you back off, it smooths out when it shifts into overdrive. I haven't had it to a mechanic to check any codes yet.

And if I have to sift through one more "My O/D light is blinking."
I have a 2000 F350 7.3 4x4 SRW CC with several issues but right now I'd like to address the one plaguing my transmission. If I crank the truck and take off it will not shift out of first gear, well it might but it'll take a while, be at high rpms, and a hard shift, throwing the 1-2 shift error code. Now if I disable O/D with the button on the shifter and take off it shifts through all gears fine. I can drive it normally and if I hit the highway, when I'm up to speed I can enable O/D, it shifts into O/D and I can keep on trucking. When I stop I disable O/D and take off normally again. After about 10 minutes of driving and several start/stops even with O/D disabled it will eventually throw the 1-2 shift error code and give me a harder shift into 2nd and I guess enters its limp mode but is still drivable. This appears to be the only code dealing with the transmission.
Due to the fact that it shifts fine with O/D disabled, doesn't skip any gears, and I can manually shift it through 1-2-D I'm guessing it's not the mechanical diode I've heard so much about but an electrical issue. Before I bought this truck it had been abused, at one point the front driveshaft came loose and ripped the wiring harness going to the TRS in half. They soldered it back together but it still looks a little rough. I figure this is a good place to start. What readings I should get at the TRS? Sensor side and plug side. I have the AE enhanced ford bundle and a good DVM. If the TRS can't cause an issue like this where do I go from here, shift solenoid?
TLDR Version
2000 F350 7.3 4x4 SRW CC
Won't shift out of first with O/D enabled.
Shifts fine with O/D disabled.
Can manually shift through all gears.
Eventually throws 1-2 shift error code.
TRS/TRS Harness has been damaged in the past.
Appears to be an electrical issue with the transmission.
Can the TRS cause an issue like this?
How do I test the TRS/Harness?
If not the TRS what could it be, shift solenoid?
Ford Super Duty (1999-2016) :: 1994 F250 - Transmission Shifts Hard With No Warning Lights?
I have a 1994 F-250 XLT heavy duty model. No warning lights are on. A few times a month my transmission will start shifting hard, kicking into the next gear. The odd thing is, if I reset the computer it stops. Shifts smooth as butter. The fluid is a vibrant red and the fluid looks great like it's new. What is going on? I'm getting tired of having this happen. The truck has 108,500 miles on it.

Truck: 2001Ford F350 5.4 auto 4x4
Issue: Engine seems to free rev over 2500 RPMs. Barely hits 50 MPH. Revs fine in park, no power in gear. At 1/4 throttle it will move, but sluggish at best. Once you get around 2500 RPMs it stops accelerating and just revs. Does this in every gear, and gets worse the faster you go. feels like its stuck inbetween gears almost. No CEL's
Replaced: MAF, TPS, Trans fluid and filter, fuel filter, cleaned intake system, fuel system treatment, O2 sensors. Trans fluid was dark, but no burnt smell.
I'm about to pull the exhaust and look for a clogged cat.
Ford 7.3L Power Stroke (1999-2003) :: 2001 - Trans Shifts Hard Sometimes
2001 7.3 auto, 2wdr, 291,000, Transmission sometimes shifts hard from 1st-2nd, 2nd-3rd. Problem started after I found trans dip stick tube broken and loss of fluid. Anything I can do without going to a shop. I've replaced the Broken Tube.
View 2 RepliesFord 7.3L Power Stroke (1999-2003) :: 4R100 Trans Shifts Hard When In Any Position Other Than Stock
I just bought a 2002 F250 7.3 4x4 auto. It had a TS 6 position tuner installed. In stock mode, I got about 11 mpg. I wasn't too impressed. I found that when I left it in 75hp mode, my mileage went up to 21. I drive easy and try to keep shifts at or below 2,000 rpm. The problem is that, when in any position other than stock, my transmission shifts HARD.
My question is: what's going on here? Does the TS change the transmission shifts? Or is the extra bump in power enough to stress the tranny? Based on the factory gauge, the transmission is not running hot. The fluid is nice and pink with no odors or metal shavings. I'd hate to prematurely kill my transmission, but nearly doubling my fuel mileage is hard to pass up.
Ford Super Duty (1999-2016) :: 2012 F250 - Hissing Between Shifts When Run WOT
2012 F-250 6.2 gas 4X4 SC/SB: when I run WOT, or near that, from a slow speed, I hear a short "hiss" between the 1-2, 2-3, and i think 3-4 shifts. I can also feel that the engine eases up quite a bit during the shift, and it is kind of a slow, soft shift. It has about 2,000 miles on it. I bought it in March 2013 as a leftover (great price!). The door sticker says it was manufactured in 4/2012, so it sat on the lot for quite a while before i bought it. But i don't remember it doing this when it was newer (~500 miles).
With the lite weight of this configuration (it is an XL so it isn't even carrying around 4 speakers ha ha), and me rarely carrying a very heavy load (yet) or towing anything, I rarely have to step on it very much in normal driving... it hardly ever gets above 2,500 rpm unless I am just running it faster for fun.
The hiss and slow shift happen at any transmission temperature. Of course, it never has been above the left side of the "gear" pic on the temp gauge, where it always is after full warm-up. Well, I'm hoping it is just shifting soft like this because it has "learned" my lite-foot driving style (even when I'm in a hurry of course the engine rarely has to work very hard).
Ford Super Duty (1999-2016) :: 2003 F350 - Hard Or No Start / Shaking In Low RPMs / Slow Response From Gas Pedal
I need fixing my 2003 f350 6.0 diesel, I have been working on this truck for a while and still am having problems, here was the original symptoms:
-Hard start or no start on a sunny day
-Rough idle for 10-15 minutes
-Rough shaking in the low RPMs (35 mph)[/COLOR]
-Slow response from the gas pedal
-boost would only get to 14
My dad and I then did many things to the truck in the shop, those things are:
-Air test and replacement of coupling going into oil branches (next to HPOP)
-Replaced EGR valve (no good)
-Replaced ICP sensor (leaking oil)
-Replaced ICP sensor and IPR valve piggtails (due to frayed wires)
-Cleaned Turbo
-Cut MAP sensor hose and reattached it (spliced on the end)
-New battery
-Performed a bubble test and found two bad injectors on passenger side (injectors #5 and #7)
-Cleaned and lubed tops of injectors
-Replaced O rings and copper crush washers on all injectors
-Replaced nipple cup O rings (tight)
-Blew out injector cups
-Bubble tested after injectors put back in (no more bubbles)
-New FICM, EGR cooler and oil cooler were already installed
-Ohm'd main engine wiring harness (good to go)
-Taped up frayed wires on fan clutch connection
-Increased wire gauge on the positive jumper between both batteries
-Sanded each ground on the batteries and engine, cleaned battery clamps, lithium greased connection points.
-Checked fuel for air (no air)
-Checked fuel psi (85 psi, plenty)
-Oil changed
After doing all of this (diagnosing as we fixed each thing) we now fixed many things including the hard/no start problem. Now, for the first three to five minutes:
-It starts right up
-Runs perfectly, no shake and instant response from the gas pedal and turbo
-Boost goes to 28
-ICP is 800-950 on idle
-IPR is 25-26.9% closed
After five minutes however:
-Starts to shake
-IPR % starts to raise
-Received no response from gas pedal (absolutely no power)
This truck has been torn apart like 8 times and I have to do it on my spare time.
Golf IV / Jetta IV :: Overfilling Trans Causing Hard Shifts - Check Engine Light Came On
Will overfilling transmission fluid cause hard shifts? I used ~4.3 quarts to refill. How much should I drain out? My check engine light came on.
Basically, I am having hard shifts from 2-3 and 3-4 in tip mode and auto. more tip mode tho.
-I did a complete solenoid change b/c of cold start problem with n92 solenoid.
Fixed the cold start shifting out of first.
-Did a trans fluid change with Mercon V ATF Fluid works fine.
-Just changed oil on 4th of July last week.
Yesterday my check engine light came on. It's been about 500 miles since the solenoid change/trans fluid change, and 100 miles since the oil change.
Now my Mk4 is having this obnoxious shifting. I am thinking I possibly added too much trans fluid into my system as I do not have the VAGcom tool.
I drained out (bone dry drain till no more dripping from check/drain plug), roughly 4 quarts. I added 4.3 give or take 0.1 quarts back into the car.
Now I'm worried because everywhere I'm reading says anywhere from as little as 2.1 quarts to 3.5 quarts.
Should I drain out 0.5 quarts (because I know theres over 4 in there now) to make it 3.5 quarts?
Or should I just redrain the whole thing and start by measure one quart at a time?
Ford Super Duty (1999-2016) :: 2006 F250 Truck Shifts Into Neutral When Driving Uphill At 40 MPH
Driving up a slight hill unloaded yesterday at about 40mph constant pedal pressure the truck shifts into neutral...at least that's what it feels like. Revs go up and no power. When I take my foot off the pedal the transmission catches and drives fine. There is no bucking or hard shifting, just that slipping. What it could be? This problem arose suddenly....never had any problems prior. It is not an issue that has gotten worse over time...

2007 escape 4wd 3.0. I've notice some random hard shifts for the past month and today the trans has trouble shifting out of 1st. If I get the rpms between 3,000-4,000 and ease off the accelerator pedal it shifts into 2nd without drama. It will not shift at lower rpms with the same easing off the pedal. The trans light is steadily blinking.

My transmission is having issues switching from 1st to 2nd gear and same issue from 5th to 6th. What happens, (when attempting to switch from 1st to 2nd) RPMs rev up high (as though it is in Neutral) then after 2-3 sec it shifts, car jumps crazy and in like 1 sec it shifts down (to 1st - RPMs jump) then shifts to 2nd gear and from there it is fine. 3rd to 4th, to 5th is great, but 5th to 6th same issue, not as extreme, but similar. If i let go of gas when it should shift to 2nd gear, and wait like 2 sec, it will be in 2nd gear without jerking - Normal.
Sometimes in Park there is this noise as though something metal is hitting another metal part, and I can feel it in car - but it goes away and only happens from time to time. Also Neutral on rare occasion works as Reverse - super rare. I did Stall test (per Hyundai procedure Bulletin 13-AT-007) - no issues. Dealer ran diagnostic - no Codes in transmission. Flushed fluid - didn't work. I drained fluid again, put new fluid in and checked ATF level per 13-AT-006 - no difference. Tested Solenoids - no problem there. What could be an issue with my transmission?? 2012 Sonata GLS 2.4L with 7k miles.
Ford Transmission :: 1993 F350 - 4EOD Shifts Hard
I have 1993 F-350, 4X4, four door with a 460 fuelie and a 4EOD. That"s a bunch of 4's! I bought this pickup with 186,000 miles on it in 2005 or so, really just to haul fire wood and go to the dump once every 6 months. I don't know if the the tranny has ever been rebuilt. Nothing else on the pickup has been rebuilt. It now has 196,000 miles on it. In the past the tranny always shifted like a stock 4EOD. Kind of slides into the first three gears then into overdrive pretty solid. I took it out to go to the dump last week and it was just like always until it took it to taco party last night and it started to shift real abrupty. Doesn't matter how fast you go, it hits just as hard if you are on the gas or just casually cruising. It is hard in every gear. My first thought was that it may be low on fluid. When it is hot, idling in park after a drive I don't see oil in the little holes on the dip stick. I see oil on the dip stick but not in the little holes. Am I correct in thinking I should see oil in the holes? Actually I will see oil in the little holes when I first pull it out, then if i wipe it, put it back in, I see no oil in the holes. Engine idling in park of course.
View 2 RepliesElantra XD (2001-06) :: Trans Shifts Hard And Slips A Little From Third To Fourth
I have a 2002 Elantra GLS with the 4 speed auto and in the mornings or after sitting in lot at work for 9 hours, the trans shifts hard from second to third (almost as if it has a shift kit) and slips a little from third to fourth. The TPS was changed once and that seemed to eliminate problems at the 26K mark. I have 109K on it now and at around 80k took it in to the dealer with the receipt for the same complaint and what was done the first time. Dealer kept overnight and said there were no problems. I do know from having a performance TH350 built that the harder a trans shifts (up to a point) the longer it will last due to less friction on clutches and bands.
