I take my 93 f150 up to 20 mph let off and it skips to 3rd it has an e4od I changed the trans out of a truck that shifted great now it still the same the only thing I didnt change is the tq converter could a bad tq converter let skip a gear? If I pull it down to second it uses second but slips under power?

 

check your speed sensor? not entirely sure on this one but i think i had a friend with a jeep that did this and that was his problem i believe.. will call him tomorrow to verify

 

Pull the DTC codes.. Sounds like you have a code that was causing a problem before and still is...

The E4OD is COMPLETELY computer controlled, any trouble code can and most of the time cause the E4OD to go into limp mode, as it sounds like yours has..

 

Can I disconnect the batt termanal to clear the codes?

 

sometimes your computers don't just clear from disconnecting.. maybe try having your local parts shop clear your codes if you are able to safely drive it to one

 

If you clear them they will just come back again.. You need to find the problem and fix it before you ruin this fresh E4OD..

 

With the new tranny when I put it in reverse it dies feels like its trying to take off in real tall gear?

 

I just tried to drive it after clearing the codes I lost all gears but 1rst

 

2nd gear is limp mode for most electronic transmissions. E4ODs also can have a problem with the filter coming loose and touching the bottom of the pan, causing a stall when engaging drive or reverse.

You could get lucky and have a sensor that went bad on you, or you could have burned up everything you just fixed by not following directions.

 

Read post #3 and #6 again!!!!!

 

My tranny is not in limp mode!! It only has first gear limp mode is when its stuck in second ?

 

So when you swapped out the tranny is it possible that you didn't hook something up correctly?

I'm even more curious to know- what year/model truck did you get the other tranny from? It's possible a different year tranny out of a different model truck could be working improperly in your F150.

 

My truck is a 93 the truck I got the tranny out of was a 95 I drove the 95 it shifted very nice only had 111,000 so I pulled it and put it in my 93

 

Is your truck MAF [Mass Air Flow] or SD [Speed Density]?

I'm no expert but if your truck is MAF or SD, and the replacement tranny came out of a truck that was the other type, it's causing drivability issues.

It's also possible that if your truck is an OBD-I and the 95 is OBD-II that could be causing problems as well.

It's just a theory.

 

Both trucks are sd
