Ford Super Duty (1999-2016) :: Transmission Will Not Go Into Forward Gears
Dec 31, 2012
I have a 1999 F-250 4X4 7.3 lit Diesel engine. My problem is my transmission will go into reverse great no problem but it won't go forward. I have no problem rebuilding the transmission if that's what it needs, I just want to make sure there isn't a electrical issue from the PCM first?

My 2000 SD 7.3 has developed a quirk. For some reason the trans has decided to shift late in all gears. This only happens once, then resumes shifting normally. However the OD indicator on the shifter blinks from that point forward. Once the engine is shut down and restarted. The sequence starts again. Late shift, through the gears, once, then shifts normally with light blinking. Fluids are up and clean.

It seems its the 4R100 tranny non pto of course and 2wd version. I drove down the rd. after bleeding the brakes, new caliper front right, came home let it idle for about 10 min, shut her down. Went to move it about an hour later, it went into reverse no problem, then when put it in Drive it revved like it was in neutral. There was no banging, no clunking, nothing to make it seem like something catastrophic happened.
I then did a line pressure test and Reverse was fine 200 psi for sure, in drive mode however it was low like around 50 but had to rev real high to get it to 150 like 3/4 pedal and it would want to seem to go forward at a crawl but nothing more. Next I did the obvious and cheked the fluid, it was about 1/4 quart low so added a bit. The fluid did not stink and was beautiful red like new.
I then tried again... no dice same scenario. Then took off the pan, no metal chunks and virtually no dust on the magnet??? Ok so I figure maybe something with the shift valves? Took them all off and the accumulators as well, all check ***** were in place and all valves moved freely.
Now onto the the solenoid pack, checked all per manual for ohms and all were perfect reads at about 27 Ohms, except the EPC solenoid that is the big one on the pack, it should read about 3-5 ohms but this guy is about 12.5 ohms.
I spoke to a tranny shop in town and they said it would not be the EPC and that I could "unplug" the solenoid pack and It would still move forward without it but not to drive like this as line pressure would skyrocket?
Why this thing would have 200 lbs pressure for reverse and so little for forward I mean? that should mean that the pump is working great, if there was a broken something metal I figured I would hear something rubbing or banging or see some shavings? Can this be a "worn out" valve? or gasket issue?

I have a 1999 ford f250 5.4 2 wheel drive i believe its a 4r100 transmission. auto. I have reverse but no forward gears. Ive heard this is a common problem , and on my reverse it has to hit 3000 rpm before it even tries to move and D 1 2 i have nothing only thing i hear is the engine sound changes gets deeper. Do i need a whole new transmission or is this fixable.

I was driving on the highway last night when it was like somebody dropped my transmission into neutral. I was cruising at 50mph slight hill. There was no noise or any thing. Now I have nothing.
It's a 2005 f350 4x4 automatic
I can only assume I'll be needing a new transmission but I am hopeful of a small problem...

This is an early 99 f250 powerstroke 6spd manual 4wd, is it common or normal to hear a lot of transmission rattle at low rpm especially in lower gears under a load. Starting off from a dead stop it sounds awful until about 1500 rpm where it clears up (or load is reduced). I'm hoping it's just the power pulses going through splined shafts, gears, etc.
210k on the truck, just changed every fluid in it.
I've been a honda owner and mechanic for all of my driving years where shifting at 8500 rpm is common and now I'm having a hard time learning what this thing likes, rpm ranges to avoid, ect; even shifting I find difficult. At least you can heel toe with the pedal arrangement...

My buddy's 2001 7.3L F350 has had 3 transmissions. Rebuilt and used. Once the new trans is in he goes like 15 miles and then is starts shifting hard and grinding gears. What this could be?

I have a F150, 2nd 4.6, 122,000 miles. No forward gears. When put in drive, you can feel it trying to engage, but doesn't engage completely. Reverse is a solid engagement. Replaced filter and fluid, same issue.

I recently bought a decent looking 1999 f250 4x4 5.4 auto. It has no forward gears and will only move in reverse. I topped off the fluids and have found no leaks so far the cooler lines are crusty but dry. I am gonna need to swap this thing out or do some more trouble shooting if there may be a non rebuild issue to solve.

My 1999 7.3l Disel 4x4 transmission quit on me the other day. No forward or reverse. Got towed to my regular repair shop, and they are treating the transmission as a black box and recommending total replacement. The diagnostics they performed were to make sure it was shifting, and that indeed it wasn't going forward or reverse. They drained the fluid and said "it's pitch black" and said it had to be completely replaced.
Fluid level was OK, and it wasn't hot. I was driving along, and merging onto the highway. It downshifted, shuddred, and nadda. Free rev. I coasted to the next exit and into a parking lot. Verified that it was shifting, checked Rev and all forwards. It wouldn't shift into 4W, and 1-2 also wouldn't move.
I'm trying to figure out what might have happened... and if it's worth trying to have the truck towed to a transmission shop and have them diagnose and rebuild, vs just getting a remanufactured transmission. None of the local wreckers have any used transmissions, and the cost between a reman and a used is pretty negligible...
Not sure what the symptoms points to for exact failure mode, be it the torque converter, pump, input shaft, etc... I've never had an automatic transmission apart before, but built plenty of motors and am a machinist by trade. My preference is to try and root cause the failure...

I have a 99 v8 with a 8" lift. I just added a front leveling (mini spring pack) to replace the lifting block (death trap). Anyways after I installed the 2" spring pack and removed the 1.5" block the truck will not go into 4wd. Did I do something wrong? I did not unhook anything. I just unbolted the spring and shocks, lowered the axle down, then installed the new springs. By the way it has the warren aftermarket manual hubs (lock or free). I can hear the t-case engaging and the light says its in 4wd.

I have a 1999 F450 that was bought new as a cab and chassis. The truck belonged to my dad who passed away two years ago and now I have it. I am wondering if it has 4.30 or 4.88 gears. The rear end is huge! It has an aluminum cover with cooling fins on it, not sure if they both had that or not. I looked online and I think it said all cab and chassis had 4.88?

Have 2001 F-250 7.3 PSD, automatic, ESOF (had to replace the original hubs with Warns)have kept up the maintenance,oil, grease, ATF fluid & filter, truck has been virtually trouble free. About 2 weeks ago I decided to go across an area of the lawn, as I was going (in 2 wheel drive)I felt the tires spin a little so I stopped got out and locked the hubs, got back in truck turned t-case to 4 high. had to rock the truck out of a damp area but nothing really.
So I got back to where I came in at (in reverse about 100') stopped put it back in 2 wheel drive, tried to go forward, very difficult, sluggish, got back in driveway had to back the truck in, will not go forward at all now. Checked all fuses, rapped the the t-case motor, no codes. So I thought I'd move the ruck, have a winch that will pull it out by the barn, I could not even move the truck forward by pulling it with a winch. As I said have never had any problems with truck. Transmission fluid is good, clean no burnt smell.

2003 F250 SC Lariat. 4x4, 6spd manual transmission, Manual hubs and manual 4wd shift. The truck shifts into 4wd perfectly. When I shift back into 2wd the transfer case stays in 4wd. If I back up it will go into 2wd.

2011 F250 6.7L Powerstroke, automatic tranny, Electric Locking Diff
When I engage the On the Fly 4WD switch the indicator panel says "shift to 4x4H in Progress" and everything seems fine but if I am not moving forward when I shift the 4WD doesn't engage. The engine revs up but nothing happens. When I release the accelerator the transfer case bangs like it is going to rip out of the truck. In reverse it is even worse. I am lucky that I didn't gun it or I could have done allot of potential damage. All my other Ford 4WD vehicles engage immediately from a full stopped position. This is quite of troublesome because if you have to shift when your stuck in the mud, your still stuck. If I shift while moving forward it works just fine.
My question is: Does this particular model (2011 F250 6.7L Powerstroke with an automatic tranny) have to be moving forward in order for the 4WD to engage?

I've got a 2003 350 7.3, with the zf6, approx 225000. I've been chasing a vibration that can be felt in the whole truck for quite a while. Feels like a wheel bearing danm near shot. But after replacing both wheel bearings and making over the whole front end it didn't go away. So I replaced the clutch and throw out bearing cause it was getting bad anyway. The vi ration is still there so I checked the harmonic balancer and it was bad so I replaced that. Still no dice. I know that it's coming from the trans, you can hear it in when jacked up and running in gear. Shifts fine in all gears. But the vibration/ clunking is there in all gears and it's getting bad. It feels like a bearing going out. Could it be input shaft bearing or pilot?

Just bought my f250 and trying to diagnose the power seats. Both the drivers and passengers seats will not move forward or backwards. All other functions are working perfectly. The motor is not engaging in either direction. The tracks are not jammed. I'm thinking its a switch issue but what are the chances both have the same issue. Is there a way to test the switches? Looking for a wiring diagram showing pin outs of each wire and their function?

I have a problem. 2002 F-350 4R100 tranny. Put a reman transmission in about 30000kms ago. pulled excellent with no problems. shut it off for night. In the morning it had absolutly no forward and a little bit of slipping reverse for a few minutes now it is totally dead. No movement either way. The OD on off flashed a few times but not anymore. Put a Genisys scanner on and no codes at all. What could be the issue?

02 F250 with 7.3. When I activate the 4WD, my light comes on, the A/C quits blowing out of the forward vents and goes into defrost and no 4WD. If I sit and wait a bit, the air again blows out the front vents and the 4WD engages. I figure I have a vacuum leak somewhere in the 4WD system. Is there a common place for this to happen or do I need to trace the whole system down? Also my manual hubs has never been turned and of course they won't. I know better than use a wrench so is there a easy way to free them up or just go ahead and disassemble and clean?

I have a 2005 F250 King Ranch 4X4 Diesel and now experiencing an issue with the front seat belts
The problem is while being worn sometimes they will not let you lean forward- they act like you have a foot on the brake pedal and are locked-you have to lean back and forth several times to get them to let out if reaching for something on the dash etc..
I have searched the forum and found many issues where the seat belts stopped retracting- but my issue seems to be unique in that the seat belt will at times 'Not Let Out" when you lean forward.
