Does it seem to matter if its very light throttle, or moderate to heavy acceleration?

No shift kit, I don't THINK the modulator is adjustable (I didn't know you could even get one!). My son will be home tomorrow and I'll check. Cats? we gutted them. It was down on power and just seemed choked, so we gutted them. We will replace them with a high flow soon, when we add a Flowmaster. Moderate to heavy. Under light throttle it seems to shift just fine.

Thanks brotherman...

My situation is I was driving doing 55 mph and all of a sudden the engine revs freely like it is in neutral. I am in gear, but no forward movement. As the truck is slowing down I start shifting it into different gears to see if anything works. Nothing. As I almost come to a stop, it all of a sudden catches and I am able to accelerate. I manually shift back up through the gears, but when I put it into OD the engine revs freely again. So I leave it in Drive and limp it home.

I park it in the driveway and check the trans fluid. Fluid is full, red, and doesn't smell burnt. I jump back in and I have no forward gears, but I do have reverse. Don't have time to mess with it so I leave it for a couple of days.

Find time to do some more checking. No leaking fluid, no forward gears, but still have reverse. I decide to try the transfer case. 4-hi, still nothing. 4-low and I have forward movement except for in OD. I put it back into 2WD and I still have forward movement in all gears except for OD.

So what does this mean and how do I fix it?

The pressure controller is easy, pull the pan and there it is.

I really dont know if the machining is the same, but I suspect no.

Or can the two solenoid valve body be converted to a single solenoid valve body?

First guess, overdrive clutch and/or od overunning roller clutch.

Can you direct me to a resource on how to fix that?

Thanks for quick reply Fordman.

First, I,d verify the shifter is adjusted properly, it could cause it, but I suspect its internal. Basically, youll need to pull the tranny and tear it down. The ATSG manual is the most informative for the job, and I believe it is on file on this site.

Thanks Fordman. Wish it was the shifter, but it is not. It is definitely internal to the trans. So I have some work ahead of me. Thanks again.

Default woops...

Somewhere I stated that the 4.0 had a heaftier od clutch, but that was wrong. It has a heaftier forward clutch. I am going to put a list of clutch specs together from 85 to 91, and assume 92 to 94 are same. The year Ford changed the clutch thickness was 1990, and if you use pre 90 clutches in a post 90 tranny, and visa versa it will fail.

Short update. I tore the spare A4LD apart, all the clutches and bands look new. The clutch frictions still have the writing on them. It has the snap together sunshell, and the center support with the needle bearings. Not sure why it was tossed. Will pressure check everything before reassembly.

Also took the trans (A4LD) out of my truck and found the overdrive band burnt. (again) but the frictions and steels still with the printing still on it. When I adjusted the overdrive band, I torqued to 10foot pounds, then backed out 1 1/2 turns. Still too tight? No other damage found in the trans out of the pickup.

Any tips to keep the over drive band from burning again? Am I not adjusting it correctly? Could I have a valve on the valve body leaking or a bad servo?
