conflicting diagnosis

E4od has been giving me grief again shifting hard. It has been serviced regularly, has good pink fluid but bangs hard occasionally shifting up and down first to second. Aamco diagnosis, rebuild it. A local transmission guy (with shop floor you could eat off of), said pour some lube guard in it to free it up if its just sticking, and if that doesn't work he said when they shift hard he changes the solenoid pack. He said there are three different packs depending on color, but its about $100 for the part and $150 to swap it out. He also said normally he would recommend a shift kit, but since it already has one, that is most likely not the problem. Any opinions? (oh and the code was shift solenoid malfunction)

Re: conflicting diagnosis

If you have a code for a shift solenoid malfunction you need to correct that. It might take a new solenoid pack, or it might be a wiring problem. Rebuilding the trans is only the answer if you are an AAMCO franchise. That is their answer for EVERY problem.

This is the same behavior it did before another rebuild which leads me toward the wiring. I found the plug right on top of the shift selector was about half way undone, but plugging it all the way back in didn't cure anything. I looked at it for a burned connector or something from arcing but its covered in dielectric grease so a little hard to tell.

Re: conflicting diagnosis

I have had a similar problem with my e4od. It found that my icp sensor was slightly off one way. I replaced it with a none ford one , and now it shifts too soft. I will be getting a international one soon.
This may help you.

you mean off like crooked or off like wrong pressure?

Re: conflicting diagnosis

The signal from the sensor to the computer and how it is interpreted by the computer. It gives me a good pressure but I have tried other and the trans shifts different with each one. Not too sure why, I need a dyno to see why.

Re: conflicting diagnosis

This thing is driving me whacko, or more whacko anyway. After finding the slightly ajar plug on the trans and plugging it all the way in, and adding the lube gard. The next day it starting working perfect. Did so for about a week. Then after sitting 3 or 4 days, it started doing it again. It did it most of the day yesterday until last night and starting working good again. I know that doing it after sitting should be a clue, but I just don't know what the clue is.

Re: conflicting diagnosis

The clue is that there is a wiring problem. If you don't have the experience and the tools to find it you may need to take it to a good independent shop to find the problem. I've found that too many Ford dealers have parts replacers, not good technicians.

Re: conflicting diagnosis

is the harness part of the transmission replaceable? meaning is there a plug on both ends and I can just swap it out?

Re: conflicting diagnosis

There isn't a harness inside the trans. The connector for the solenoid body pokes through the case and that's what the harness plugs into.
