Ford Super Duty (1999-2016) :: 2001 F250 - Overheating - Replacing Bypass Valve On Trans?
I am having some trouble with my 4R100 overheating.
Truck is a 2001 F250 XLT 7.3L with 244k miles on it. According to previous owner, the transmission was replaced around 185/190k but there was no paperwork to prove it.
I recently had a leak from one of transmission lines coming into the bottom of the radiator (the one on the passenger side). I replaced it and topped off the little bit of fluid that leaked out. Last weekend I installed a temp sensor in the transmission and hooked it up to my pillar gauges. The first few days driving with it, the temp was at/around 180 degrees, 25-30 degree outside air, unloaded on the highway averaging 70-75mph.
Today on the way home, the temp got to 180 after 35-40min of driving then continue climbing. I pulled off the highway after 1.5hrs and the temp was almost at 210 degrees. I let it idle for 5-10min and the temp didn't change. I turned it off and let it sit for 15 min. Upon starting it back up, the temp had dropped to 180. I continued driving and the temp climbed back up to 210 within 35 minutes. (65-75mph, 24 degree outside temp, unloaded). Once off the highway I averaged 35-45mph on the back roads to my house. The temp started to drop back towards 180 degrees.
Before I start throwing money at it, and installing a 6.0 cooler etc. I am thinking there is something else wrong here. I am going to look at new lines and replacing/repairing the bypass valve on the transmission. I am driving 2hrs to work each way and thats when the temp really starts to go up. The fluid doesnt smell burnt, its still nice and red. I am going to try and flush the lines this weekend and see if something is plugged/caught. I ordered an inline filter today and will put that in with a new hose from the transmission to the radiator (old one is rusted).
Ford Super Duty (1999-2016) :: Trans Slipping When Taking Off From A Stop Light
99 F250 7.3 everyday worker, just recently my tranny slipped as I was taking off from a light, I thought hmm that's odd! Pulled away from the next light , it did not slip! Later in the day did it again, so I ran by the transmission shop to have a service done, to my surprise I was told service would not work, and a rebuild was going to be 3200-4k. truck has been used lightly for the last week or so, slips sometimes and not others. I still believe I need to have it serviced? can I do this myself ( I haven't a clue)....

I been having a issue with my truck lately. It's a 2008 with only 88,000 miles. When doing 55mph it feels like the transmission is slipping. Sometimes it will do it over and over. If I speed up to about 60mph it goes away.its has gotten worse in the last month or so. Hoping it's nothing major.
View 6 RepliesFord Super Duty (1999-2016) :: F250 - Transmission Fluid Is Low / Slipping
1999 F250 SD... Tranny fluid is low, tranny slipped one time on me. I checked the fluid and it's low. No drips on the garage floor, so I'll have to inspect closer. But my question is can I add new fluid without screwing it up even more? It's got 170,000 miles and I doubt the fluid has ever been changed. I just bought the truck last week, so I can't say for sure, but it hasn't had a regular flush or change. It doesn't smell burnt but it's just a little darker than new fluid. I was told by the guy I bought it from that the torque converter was changed in it not too long ago.

I have a 2001 Ford F-250 with the gas v-10. Yesterday it started just fine as always. Today I get into it and it starts to turn over just fine then starts to make a grinding sound and the truck won't start. I have had a fuel issue in the mornings with once it started you had to barely press the gass to keep it running. But never makes a funny sound and always runs fine. This only last for a couple of min and then it runs fine for the rest of the day. The grinding is not the starter. I took it off and had it checked and it was fine.
The truck had been using oil. When I checked the oil level it was low but it was still on the stick. "I know a motor needs oil to run smooth but it's my dads truck and well let's just say he is not the best on maintenance". Also I smelled the oil and it does have a gas smell to it. So it definitely does have some gas in the oil. I tried to light the dipstick with a lighter and it wouldn't light. So not sure how much gas is in it but that's what I did.
So the question is, would something just in mid crank go bad and then not let the motor crank. Truck made no weird noises before this so I find it hard to believe the barrings just went out in mid crank and now it is shot.
Also I just checked compression on front cylinders.
Driver side read 75lbs
passenger side read 100lbs
Ford Super Duty (1999-2016) :: 2011 F250 - Transmission Slipping For A Second When Accelerate
2011 f250 gas 4x4... I bought last year with 65k miles, now has 105k. sometimes when accelerating it slips for a second like a manual would if you jabbed the clutch while pulling. I had the 100k trans flush done. I noticed it a couple times before but more frequent recently. How concerned should i be?

I have a older minimax with the latest updates and have noticed that under full acceleration the tranny seems to rev up faster than the truck is accelerating. This occurs i think in 3rd gear like accelerating onto a on ramp etc. Kinda like its slipping if you know what I mean. I'm running the mild tunes in tow mode. Everything else seems ok.

I bought my F-250 Super Duty 6.0 last October, and I am extremely happy with it comparing to my former '03 Dodge 2500 TD. The Ford drives so much better!
There is only one problem I have with it. Without pulling it shifts nice and has lots of power. A Month ago I bought a fifth wheel trailer and I hardly notice it behind the truck, also it doesn't use more diesel pulling. However going uphill the transmission seems to slip, and I can hear (sounds like) a fan running loud? I loose speed.
All the temperature gauges stay normal, no difference. It starts to pull worse. I replaced de tranny filters, inside and the outside one. Also I did put the correct transmission fluid in there, no difference. Almost no grindings in the oilpan/magnet.
I looked on many sites, but cannot find anything on this. Personally I think it's the torque converter? My final step would be to have the transmission rebuild, with the best parts available, (close to WA, ID, MO)...
Ford Super Duty (1999-2016) :: 2011 F250 Loses Power And Tranny Is Slipping
Heard a 2011 F250 gaser while driving in the morning just falls flat on its face, almost like its starving for fuel as well as it feels like the tranny is slipping too. What this could be? I am not sure if its electrical or what.

I just bought a 95 f250 4x4 with the 460. The guy i bought it from had a trans slipping towed it to the shop when the shop went to pull it in they started it put in gear and engine died. The motor is now tight w no movement either direction with a bar obo it. Is it possible the trans is holding the motor tight? What can I do?

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........

I have noticed my trans temp gauge needle is dead center of the gauge even on a cold start. I thought my sensor was under the pan so I pulled it and did not see any sensor at all. Is there a external sensor?

I have a 2006 F250 with the 6.0 PowerStroke and automatic transmission. I just purchased this truck at an auction about a month ago.
Today I notice the transmission is not shifting into overdrive. No warning lights. If I press the tow/haul button in no change but the tow/haul light does come on. If I press it again (to turn it off) the tow/haul light goes out but still the transmission will not shift into overdrive.
This leaves me at about 2000 RPM at 68 MPH. I just had a Ford dealer perform Transmission service last week. (20,000 miles after the last recorded service.)
I am already not happy with the service I received at the dealer so I am really hesitant to take it back to them if it is something not related to the transmission service they performed.
Ford Super Duty (1999-2016) :: Engine Swap 2006 F250 5.4 To 1000 7.3 Trans?
My dad has a 2006 F-250 5.4 3v that spun a rod bearing at 107,383 miles. He's never been thrilled with the performance of it (told him he should have gotten the 6.0 when he bought the truck new, but why listen to a 15 yr old ). We've been throwing around a couple different ideas for engine swaps since the 5.4 is dead. We scored a 5.4 2V Lightning engine, but after trying to figure out transmission controllers or if we'd be able to tune the stock PCM for the 2v, we've put the project on hold.
Recently, I've been trying to convince him to do a diesel swap over the L-motor. I have a friend selling a cheap 99 7.3 with trans, PCM, harness, intercooler, piping and other misc stuff. Would that harness generally be plug and play with the body of the 06? Would it be more worthwhile to try to find a 6.0 from 05-07 and swap everything over?
I've also been considering a Cummins swap, although I haven't gone much past looking at complete engines on eBay and Craigslist. Would this be the better route, and just get a standalone controller for the 5R110?
So I'm looking for other's opinions. Should we go 7.3, 6.0 or Cummins? Should we stick with gas over diesel? Try to make the Lightning motor work? Or just go back with a stock 5.4 3V? I should say, he won't sell the truck for whatever reason, so he's not worried about resale or anything. We're in Michigan, so we don't have to worry about emissions. And we're fairly mechanically inclined, so I'm not too worried about doing the swaps, however my knowledge on diesels is limited.

View 6 RepliesFord Super Duty (1999-2016) :: 2014 F250 - Indicator Showed 5th Gear But Trans Feels Like In Neutral
I have a 2014 f250 with the 6.2 and just turned 13,800 miles. I tend to drive in tow haul a lot, while not towing because I like the shift pattern better and saves on brakes while stopping. Last night I slowed to a stop sign, came to complete stop. Went to take off slowly like always and the truck was like in neutral, looked down and the indicator showed 5th gear. Let off and watched it go to 1st and took off no problem. This all took only half a second or so, seemed fine after that. What might of happened?
