I have a 94 F350 with the e4od. The transmission doesn't shift properly unless I let up on the gas before each gear , then it shifts nice. The trany is totally rebuilt. My tranny guy is confident the trans mechanically sound he even took it back out and went through it again. I am on here just tring to get input to pass on to him .Thanks for any info you can share.

No offense but your on here looking for advice to give your tranny guy, you need a new tranny guy.

Are you getting any codes?

He came up with no codes. He took the old codes off . I do wonder if he is using the right code reader though. Any suggestions?

 

You can scan for codes yourself, look here:
EEC IV Self Test hookup

From what I understand there are three sensors, the Vss, TPS, and MLPS and they are what control what your tranny does, if one sends a bad or no signal it will throw your shifting out of whack. I have a similar problem with my tranny that I've been trying to figure out right now, waiting for parts.

Thanks Scott, If you don't mind I will keep you posted after I give this a try. Thanks again

I noticed the speedometer is irratic (slightly between 35 and 45 mph) how do I start to test it and what voltage am I looking for and do you have to take the dash off?
