Ford 6.7L Power Stroke Diesel :: 6r140 - Transmission Slams Hard Into Reverse / Shifting From 1 To 3 Is Awful
I'm having problems with my 6r140 in my 2011, the truck is an early build around 8/2010 I believe.
After cold soak when shifting into reverse after allowing engine to warm a bit the transmission almost always slams hard into reverse.
After that shifting from 1-3 is awful, the transmission will try to go into 3rd but downshift to 1st then fail to go back into 3rd multiple times. This situation is extremely dangerous when trying to pull into traffic.
Oh and once the transmission gets into 3rd it will skip 4th and go right into 5th. There is only 94k miles on this transmission/truck.
I just bought this truck about a month ago, does this sound like an issue with the solenoids in the valve body?
I'm very mechanically inclined and can swap them if need be but now we're talking few hundred in solenoids and then getting the trucks pcm flashed right?
Also fluid has been changed and I used mercon lv.
Ford 6.7L Power Stroke Diesel :: 6R140 Transmission - Intermittent Misses On Gear Changes
Took my 2011 F250 in to the dealer where I purchased it concerning intermittent misses on gear changes. The dealer had no history or knowledge of problems with shift flares. I was told they would check it out. Bottom line, their checking it out yielded no results, no action, and no "engagement", pun intended, to resolve a serious concern. How did others resolve the issue when it came up?

In my 2011 F-250, 6.7, auto....it seems that at certain times went the tranny shifts from 2nd to 3rd and I pause with acceleration, for some reason the tranny seems to go into a slip mode and then slams into 3rd. Now I read about 8 months ago that there was a computer upgrade via Ford. Which they did when I was having some work done on the truck at the dealership.

I have a 2006 f250 6.0L with 76,000 miles on it. And it just started to shift softer then normal under light throttle. The first to second to third shift are softer then normal. And the third to fifth gear shift seems to have a lot of what I would call overlap and some times it feels like it is slipping. Gets better under hard acceleration but not as firm as it used to be. I have always changed the trans fluid and filter every 25,000 miles. Trans temp runs about 150 to 160deg. I checked the fluid today and it's bright red and does not smell bad. And I don't have any coeds. Could it be a solenoid going bad ?

Hauled my last 2 cord of wood for the season, and I now have a pretty good 3-5 slip in and an intermittent bang/clunk when its shifting. So I've put this off for a long while now, and I want to fix it. I've done my research, and I don't really feel like I'm any further ahead than before I did my research.
I'm looking for recommendation's on what transmission and or kit is the best for my truck. I pull my 5er 10-15 times a year mostly up and down the east coast. We are looking to get a new 5er with a bunk house, my goal is to stay in the same weight neighborhood, I run 13-13,500 now depending on where we are going. The goal is to be able to get maybe another 3-5 years of use from the truck, maybe more, and then upgrade to a newer truck. So let me hear what you all recommend as I'm going crazy and probably over researching what I'm gonna do...as usual.
Ford 6.7L Power Stroke Diesel :: Intermittent Transmission Shifting Stutter When Truck Is Cold
For those of you tuned and deleted......intermittent transmission shifting stutter is gone now? Mine sure is. Never once since the mods have I had that annoying stutter when the truck is cold and I'm easy on throttle between 2nd and 3rd gears. What a relief it is to have it shift NORMAL ALL THE TIME!!! Stutter no more after H&S Tune and Delete, for about two months now.

Can't figure out how to turn on dome light, so I broke down and did the un-thinkable, I read the manual.... from page 66
Press and hold the top of the control to the full on position to activate the "dome on" feature. This will turn on the interior courtesy lights. The lights will remain on until the bottom of the control is pressed.

And no luck. Can hold the button down for a long, long time. The dimmer function works OK so the buttons are working. I would like to be able to turn on the rear light so my kids can buckle themselves.
Ford 6.7L Power Stroke Diesel :: Auto Transmission - When Shifting Truck Will Go Into Neutral State For 2 - 5 Seconds
When taking off the 1-2 shift and the 2-3 shift the truck will go into a neutral state for 2-5 seconds. when this occurs, the rpms will rev since your foot is on the accelerator. Once you let off the accelerator the rpms come down and the gear will catch. I have had the truck in the shop a few times without any luck. part of the problem is no codes are thrown so the dealer has no clue what to look for. This is extremely dangerous when in my case i pull out on a 6 lane hwy with 55mph speed limit. Ford more or less said to pound salt until a code is thrown or until something else happens. this nearly caused a nasty wreck 2 weeks ago.
View 14 RepliesFord 6.0L Power Stroke Diesel :: Transmission Started Shifting Badly - Codes P0976 And P0755
Recently picked up a 2004 Ex 6.0L. Drove great for a bit, then it started shift badly, then finally the Tow/Haul light came on. The original codes were P0976 and P0755.
P0755 being shift solenoid B, and the P0976 being SSB Control Circuit low. I replaced Solenoid B and that code went away.
P0976 stayed with no change in how the truck drives. Replaced the internal harness today, and again no change.
At this point I'm at a loss. I'm wondering if it's something between the PCM and the transmission?
Ford Ranger / B-Series :: 1997 - Transmission Not Shifting Down Into First Gear Not Even Manually

When I'm at 60 mph and go full throttle, it doesn't seem to down shift enough and the torque seems low. But when I go 1/2-3/4 throttle, I get the power I'm looking for. I'll test it later today and see what gear it shifts to with both.
View 4 RepliesFord 6.0L Power Stroke Diesel :: 4x4 LOW Light Stays On / TC Not Shifting
2003 F250 6.0 ESOF - 4x4 and LOW lights on, TC not shifting
About the truck: 2003 F250 CCLB 6.0L 210k Miles
Heavy Duty Bulletproof Diesel Kit
Warn Front Manual Hubs (vac lines clamped/blocked)
Transfer Case Shift Motor/TCSM is off (I personally have not tested it and am still looking for what to test on it) or I will purchase a new one.
From seller: "What happened is, I accidently put it in 4x4 and when I turned the switch it would not go out. I had to limp it home slowly. When I got home I messed around with it, and could not get it to go back into 2x4. I removed the shift motor, and tested it. It tested ok. I shifted to back to 2x4 with a wrench and left it."
CURRENTLY the TCSM is off the transfer case and is in 2WD. Warn hubs are set to "FREE," seller also noted that this is how he has been driving it for quite sometime. TCSM is in 4x4 LOW, that is what I have to manually shift the transfer case to if I want to mount it up. I have been shifting it using a 14mm open end wrench and with the transmission in neutral. I have not tried turning the TCSM position manually.
Scanning using AE brings up different codes depending on transmission position and which scan is used:
P1812 4-Wheel Drive Mode Select Circuit Failure
P1819 Transmission Neutral Safety Switch Short Circuit To Ground
P1832 Transfer Case Differential Lock-Up Solenoid Circuit Failure
P1876 Transfer Case 2 Wheel Drive Solenoid Circuit Failure
P1865 Transfer Case Contact Plate Power Short to Ground
AE scanning for DTCs: P1832 and P1876
AE scanning using OnBoard System " SYSTEM SELF TEST" with transmission in PARK: P1812, P1832, P1876
AE scanning using OnBoard System " SYSTEM SELF TEST" with transmission in NEUTRAL: P1812, P1819, P1876
AE scanning with TCSM off: P1865, P1832, P1876
P1865 seems to be solved by simply installing the TCSM.
AE Live Data shows correct indicators for 4WD switch, showing corresponding drive mode in AE as the switch setting but nothing happens. No clunk/thud/movement. I have tried resetting the codes but the 4x4 and LOW lights both stay on. I tried it in park, neutral, engine off and engine on. I tried driving 5-10 mph to relieve any driveline wind up, I tried driving in reverse with front hubs free and locked, gave the same results in AE and no transfer case shifting.
Section 308-07A Four Wheel Drive Systems Pinpoint Test I
Found a thread with some fuses to check, I have checked fuses #19, 27, 31, 33, 34, 45 and 111 (with a multimeter for continuity),
Relays (first swapping the old ones, then trying new ones), I did the pinpoints from test I, and installed another GEM (same part number as mine but from a 2005 F-350)
Section 308-07A Four Wheel Drive Systems Pinpoint Test I led to my purchase of a used GEM, not knowing if it is good or bad, I have determined that I get the exact same codes for each AE Scan as the GEM that came with my truck.
I included a photo of my relay box, have any of you seen this type before? There is no other box in the engine bay with twin relays.
Air/Defrost switch works and routes air to switch setting. AC works, DEFROST works.
Could PVHS be causing a code from the manual hubs?
Could the MSS be causing a code even if it is showing correct in AE?
Should I try a new TCSM? Should I try turning the TCSM manually? How do I test, what do I test for on the TCSM?
I want to avoid taking this to the dealer if their own service manual and diagnosis is going to have the same results as my testing.
Where do I go from here?

Ford 6.7L Power Stroke Diesel :: Jerks When Shifting From 2 To 1 While Slowing Down
Trans has new solenoids in the trans but is shifting too firm sometimes from 1-2 or 2-3.. It is tolerable going up, but when slowing down it jerks really bad from 2-1. Sounds and feels horrible for the trans and miserable during stop and go traffic. Ive had to switch it to Manual and start off in 2nd gear. Im deleted, with intake, and a custom sct x4 tune. My main question is there any way a new tune could have better shift points?

View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Transmission Leaking / Irregular Shifting
Anyway I have a 2001 F250 7.3l 4X4 supercrew 8 foot bed. Have an upgraded turbo, 4" exhaust from turbo back, k&n cold intake. Has 207,000 miles on it, 198k from first owner, the rest from me. Anyway the transmission is a automatic R4100 tranny. Since I have owned it it would shift from 3rd to 4th on slight grade. It would continue to shift up and down till I got back on flat again, rpm's would not vary to much depending on the grade. So that problem continues and now today I was towing a 14' trailer with 3 wheelers on it and I smelled smoke. Pulled over and it was pouring oil from the bellhousing. I had no choice but to drive back home about 20 miles. I first stopped and poured 2qts of ATF fluid in and then babied her home. What are my options here, what I should be looking for to fix?
View 1 RepliesFord 6.7L Power Stroke Diesel :: Shifting Not Smooth From 3rd To 4th / Slight Hesitation
i bought a used 2011 F250 and really like the truck and there is no comparison when towing the trailer.
1.) I've noticed the truck doesn't shift smoothly from 3rd to 4th. Under light acceleration the RPMs climb, then drop slightly, then climb, and finally the truck shifts into 4th gear. It's almost like the truck wants to shift but doesn't. I believe a selenoid was replaced on the truck.
2.) From a dead stop, when pushing slightly on the gas pedal there is a slight hesitation or unresponsiveness with the truck wanting to proceed forward.
Ford 6.7L Power Stroke Diesel :: F350 Shifting At Lower RPMs
Just bought 2 new F-350 with 6.7s for a service truck and feed truck. I have a 2011 6.7 so pretty familiar with it. I noticed both these new trucks shift at a lot lower RPMs. At times if going from pasture to pasture I have noticed the tach at 900 rpm in 6th gear. My 2011 doesn't do that, it shifts at a higher rpm. Both of the trucks have been deleted, and I have a SCTx4 tuner in each truck and have both tuned to the lowest setting, Tow 40HP. Is this a fuel economy thing?

I recently purchased a used 2001 E350 with a 7.3L and the transmission is not shifting properly. It will go into Reverse no problem, put it in "D" and it starts in high gear and will not shift out. If I manually shift from 1 to 2 to "D" it works fine and will even go into OD. It will not down shift on its own either. What should I do to fix this issue?
