Hey Y'all, New to the thread. Anyway, straight to business. I have a 1991 F150 XLT Larriat RWD with the AOD transmission. I havent been having any transmission problems but my u-joints went bad. After I replaced them my transmission now shifts at high RPMs. 1st to 2nd at about 2000 rpm, 2nd to 3rd about 3000 to 3500 rpms, and wont shift into 4th with a stomp on the gas with a quick release. Any ideas? I'm about to give up and just rebuild the tranny.

 

Have you tried adjusting the TV cable?

 

I've tried, its properly adjusted, ive also changed fluid and filter
