Please help!
I have a 95 f-150 Eddie Bauer with a 5.8l.

I'm having an issue with it shifting while under acceleration. The engine runs smooth while in park and neutral, but when driving and given extra throttle (merging on highway) it will not shift unless I let off of the throttle.

The power seems to be there, just not shifting like it used to!

Any input helps
Thank you all in advance

 

You need to pull the codes, that trans is 100% computer controlled and it thinks there is a problem.
