Good Evening Everyone, Two quick questions . I have 1995 Ford F-250 4x4 ,E4OD tranny 5.8L there’s a E4OD out of a 1996 f-250 4x4 in it now with the same matching converter. There’s only 1st gear and reverse going down the road. Won’t shift out of first gear ? Secondly Do I have to stay with a E4OD from a 95 year only? F-150,f250,or f350 series will work?

 

95-97 will work. Truck series doesn't matter the engine that it was bolted to matters, and that it is a 4x4 transmission.

 

The engine makes the difference? Same motor 5.8l are in both trucks. Both are 4x4s. Truck won’t shift out of first gear and it does have reverse? What is it it’s been driving me nuts!

 

Yes. An E4OD from a diesel or 460 won't bolt up.

You could have a bad shift solenoid, a bad wire to the solenoid, a stuck shift valve, or a bad clutch. Are there any codes stored?

 

Thanks for your help Mark ! I appreciate your sound knowledge The solenoid pack was replaced with a fresh rebuild . Testing the wire to the solenoid for faults is easy enough. The other possibility’s stuck shift valve or bad clutch. Are testing for these faults done with a code reader? Keeping in mind that this was a working tranny when pulled from the 96.

 

If the trans worked in another truck the fault is most likely outside of the transmission. Reading the codes is an excellent way to start. It can really narrow down where you need to look.

 

Code reader gave a low voltage fault to the TPS. Would this be the problem.

 

That is a problem, but I don't think it could cause no upshifts. You should fix it and see. Even if that isn't the cause of this problem, it will be a problem shortly.

 

 

There isn't enough information. It could be a lack of vehicle speed signal. It could be a problem with intermediate clutch. It could be a stuck shift valve in the valve body.

 

 

Yes, they do.

 

Are these faults all outside the transmission? Are the selinoid packs compatible for both trucks ? There was a rebuilt pack installed in the 96. I’m not sure if it was order for the 95 or 96 ? I purchased these trucks together and this information is available.

 

1995-1997 had the same solenoid bodies. Earlier years were slightly different.

Lack of vehicle speed signal is outside the transmission. The intermediate clutch is inside the transmission. The valve body is inside the transmission pan.

 

I was surprised to see a Ford transmission engineer talking about talking about a intermediate clutch in an E40D. I thought the E40D was based on the C6 which had an intermediate band. Am I missing something? I have been out of the trans business since the early days of overdrive transmissions but the GM 350 and 400 were the only true intermediate clutches I worked on. The rest had intermediate bands.
