Trans. problem - HELP?!

I've got a 1993 F250, 460, 4X4, with a E4OD trans.....here's the problem. It was shifting really hard and slipping when it felt like it...no pattern. Took it to the trans shop and they said it's not in the tranny. Suggested a Computer.....Changed it and it shifted normal and no slipping....BUT when the Check engine light comes on it takes longer to shift, no slamming or slipping just winds up tighter. Could it be the sensor in the inst. cluster? Or anything else I am totally unaware of? About ready to pull my hair out.

Why don't you pull the codes? The computer is trying to tell you something is wrong, you should pay attention.

Or maybe something isn't properly plugged, check the connections on both the computer and the trans.

Ford Fuel Injection » How To Run a Self-Test Here is a link on how to check for trouble codes if you don`t have a code reader. Maybe try that first (as suggested by rla)

No trans codes are coming up at all, before I changed the computer it would give me "no communication" when the light would come on. I've got an EGR not opening thats it.

Fair enough. Then fix the EGR problem so that you don`t get a CEL.

Pull the VSS from the rear axle and clean it. Sometimes it gets gunked up with "stuff" from the rear axle. Not very technical terms, but you get my jest. I have seen VSS problems without ever tripping an error code. More often than not there is usually a report of erratic speedometer operation as well, but not always.
