Ford Transmission :: 1978 F250 - No Reverse Or Neutral
Apr 1, 2017
I got Ford C6 Transmission bolted up to a 460 in a 1978 Ford F250 4x4. I recently had put all new gaskets in it and I change the fluid. The day I put it all back in my reverse was trying to lunge forward, my natural was a 1st gear, and drive was working fine. Now recently my park throws itself into gear. I got no burnt fluid, the clutches were fine when I put it back in???? What could it be, I'm running out of options before I do a manual transmission swap.

I have a 1970 f250 with a factory 390 (vin verified) and a C6, I believe the transmission was rebuilt but have no way to verify. It works fine while cold and mildly warm. Once heat soaked it is very slow to shift (going from neutral to reverse can take almost 30 sec) and leaks profusely from the front. I can not tell exactly where the leak is. Could this be a case of just having too much fluid or is there a more serious concern? The dipstick does read high but level ground in my area is hard to come by so the accuracy can be questioned. If it does have to much fluid, do I just drain the pan, re-install and let it run till hot and replace fluid as needed or should I drain and replace with 3 qrts prior to starting?

I have a '78 F250 4x4 with the 400 engine and C6 automatic tranny in it. All of the sudden, it won't shift as I'm driving. It will go into reverse, drive, 2, 3, when I'm shifting, stays in the same gear all the time while I'm driving.
I was looking around and I found a hose that I think goes from the top of the tranny to...nothing. A friend said it's a vacuum hose that should go from the shift modulator to the carb. Well, I can't figure out where it should connect to the carburetor. There is a hose towards the front of the carb that was cut off and is plugged with a bolt, but that's been like that since I bought the truck 3 years ago. So if that's where the hose SHOULD go, then something else must have caused the tranny to give up on me.
Tranny has been acting fine until now. And I'm sure that hose should go SOMEWHERE!

1986 S10 blazer automatic transmission won't go into reverse OR neutral! It goes fwd in both reverse and neutral. It goes into park just fine. The fluid is full and not burnt. It will drive forward when in reverse and in neutral. I turned the engine off and checked neutral, it was not in gear but tried to go forward as soon as I started the engine.

I just recently picked up a 87 F250 with a 6.9 and a ZF5 trans. The PO replaced the clutch, and mentioned that he replaced the clutch fork too
Since I bought the truck, I've had some nasty rattling noises. It rattles when in neutral, and stops when I put the clutch in. The noise also comes back on occasion when decelerating at highway speeds, in 2nd as soon as I stop accelerating, and at low speeds in 3rd.
What is causing this?

I have a 78 4x4 I has SAT for a few years transmission has not shifted right since I've owned it. When taking off in d it just runs out first until I let off the gas then goes straight to third. Also will not go to second manually...

I have a 78 F350 2wd With a 460. I want to install a 99 E4OD trans. I have the Trans it is rebuilt with all the upgraded parts. I was going to order the converter this week. I am not shure on the best programer to order and shifter to order.

i have a 78' F-250 4x4 4 speed with a straight 6. it has headers and an eldebrock 600 on an offenhouser dual plane intake. The carb just randomly started acting up the other day and what to try now. it will sputter and just about die when i first let off the clutch then it will suddenly start racin. its really annoying and hard to drive. i checked the inline fuel filter and it should be getting plenty of gas. didn't find any vacuum leaks.

I've got a 2002 f250 7.3L 4x4 auto trans and I've done quite a bit of searching and cant seem to find any definite answer. I drove 40 miles today no problem. pulled into a stall at sonic and when I went to leave no reverse. I was even on a downhill slope, but it wouldn't budge. I got a friend to come up there and we tried to pull it, wouldn't budge.... I disconnected the driveshaft and it rolled downhill without us even having to hook onto it again. Once it was out I hopped in and put it in drive and it took right off.
It did feel like maybe I had to give it a little extra gas to get it moving but maybe I'm just paranoid. I know once I got on the road it was cruising 65 no problem in drive. I got it to my job and noticed that when I put it in reverse the OD off light flashes and if I mash the gas with it in reverse it actually acts like its trying to push it forwards. I did jack the rear end up and put it in reverse and the tires make a half rotation but in the wrong direction then come to a dead stop.... with the tires jacked up off the ground Drive would spin them, 2 would spin them, but 1 would stop them like somebody locked up the brakes.

So last weekend I installed a transgo kit for my 4R100 transmission in my 2000 F250 diesel. I didn't really care about getting a shift kit, but I had problems with delayed shifts and figured the accumulator springs had broken. It turns out that was correct, the 2nd gear spring came out in 8 pieces.
Anyway, the transmission shifts great now, but when I put it in reverse it the engine jumps up 200 rpm and then it bogs down as it engages reverse forcefully. It also does this while selecting 1st from Park.
From what I'm reading it's the TC not unlocking and/or a fluid pressure/volume issue. I've also read the filter might have fallen off, I had a hell of a time keeping it in place. I've checked the the fluid level and everything is good there. My question is when I drop the pan, aside from the filter, what should I look for?

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.

I have a '95 F-250 7.3 auto 4X4. The transfer case linkage has been floppy and prone to coming apart since I've had it, but that's been fine for me. I let my brother use the truck last weekend, and now it does the following: When you put the transmission in reverse, or when the truck overruns the engine (compression braking) it grinds badly like the transfer case isn't quite engaged. Only does it in 2 or 4 Hi, and everything's normal otherwise.
Could the transfer case have jumped out of gear while he was driving it, and he didn't know to either push it into gear or pull it into neutral before it did damage? I really don't want to pull a transfer case in my driveway in December in New England, but give it to me straight.

We installed a TransGo HD-2 "reprogramming kit" into my friends 96 F-250 460 4x4 E4OD in preparation for future engine modifications. The problem is it didn't work correctly.
All forward gears work (some shifts are harder then stock, but many of the shifts are just as soft as stock, which in itself may be another issue). We drilled the separator plate for the V8, we may try the diesel size next though...1st, 2nd, 3rd, 4th + tq lockup all work however.
Anyways, the major problem is that it no longer has reverse. If you shift from reverse to neutral, the RPM seems to go up a little bit as if it were in gear a bit, but give it some gas and it acts like it is in neutral. Obviously something went very wrong.

I've got a 76 F-250 4x4 C6 and the transmission has been kind of quirky since I've owned it. I'm starting to tow with it occasionally and I'd like to get this sorted out. It only has issues cold. After 5 minutes at most its good to go, probably more like 2-3 minutes. After that it works 100% as it should.
When cold, reverse is really weak. If I fire it up cold and go for reverse it will hardly move. If I put it in neutral and run it at 2000rpm for about 30 seconds it will pull but still weak. And after getting out on the road 1st and 2nd are great but 3rd gear is basically non-existent, all slip. I just hold it in 2nd for a few minutes then its fine. There are absolutely no issues when it warms up. I was towing my Bronco with it and absolutely no slippage at all. I'm dealing with it for now. Don't back up when cold and hold it in 2nd for a bit when cold only. That or rev it before reverse etc.
I have adjusted the band. I have never changed the fluid. I did buy new fluid for it but have not done it. Who knows that kind of fluid is even in it. The fluid is a little dark but its really not that bad and doesn't smell burnt. I'm in the market for a 4 door super duty so I might just have to limp it along until then.

1991 4x4 f250 idi w e4od w 3:55 ratio... The truck is slow to engage in reverse, about 5-10 sec. It also has a very hard shift 1-2. All other shift points are good. Drop down is good, and TC lock up happens at all the right points (feels like anyway).
I've had the truck for about 2 years now, replaced several sensors an harnesses and a full fluid change to solve other problems but this still remains.
Sometimes when I start it in the morning if I let it sit and idle for a few min it will engage reverse much quicker AND shifts way smoother and constant. Shifts smoothly thro all gears, holding a constant 1800-2000 rpms with no drop or lug. Or do I need a rebuild?

I have a 2001 F250 V10,
So the truck drove fine yesterday had zero issues... I used my auto start as I do every morning in this cold weather, get into the truck and shift from park to drive and its like it does nothing. I can free rev in N,D,1,2. Reverse works great.
I tried switching from 4wd to 2wd, no change. Reverse works just fine. No noises, codes or anything, just doesn't want to engage...
I am assuming I have a 4R100. Could something electrical cause this? I am thinking its mechanical, but hoping someone has ran into this before.
Literally no way I would have known the trans was going bad... It's always worked fine. Tranny fluid is full, I tried unplugging the battery waiting and plugging back in, no dice.

I bought late 98 F-250, 5.4 G, 4WD. OHad to replace the steering flange because they messed up the ignition cylinder and flange. Truck didn't run for 4 years. 249K miles, no history available. Got the engine running, no DTCs. D, 3, 2, 1 barely moved the truck forward but, R hauled butt in reverse. Checked transmission fluid it was good and clean.
Came back to it a few days later it threw a P0720 (output speed sensor circuit) and I have no reverse, park feels like it wants to move, R is neutral, N is forward, D is forward, 3 is forward, 2 is forward, 1 is forward. The N is full drive. I cleared the P0720 code after it came up and it has not returned. The instrument gauges work but the odometer display is intermittent. Linkage? Fluid? Sensor? Wires?

I picked up a 2016 F250 Powerstroke in the first of March. I owned a 2011 before and loved it.
The 2016 has been great so far, but I've noticed a sound that wasn't present in my 2011.
When the transmission is warmed up, I get a "cla-click" sound from the transmission area when sifting from park to reverse. It doesn't do it all the time and I can only hear it, not "feel" it.
This AM I heard a similar click sound when I came to a complete stop. I only heard it while stopping, not while taking off. I could repeat it almost every time I stopped. I was in drive the whole time I heard the click sound while stopping.
What it may be? I know sounds are one of the hardest things to communicate/diagnose.
