Default 1993 automatic trans delayed shifting issue

Recently drove car and it would not shift out of 1st gear, immediately turn back home, checked trans fluid level and found it low, i recently discovered the trans pan bolts were loose and tightened them. I added fluid, which improved the shifting but was still shifting at higher rpm than normal, shifting seemed to return to normal on a subsequent drive a couple days later and I thought all was well but now the delayed shifting has returned, it shifts between 3 and 4K rpm. The service engine soon light would come on intermittently also. I had over filled the fluid so I have performed a drain and filter replace, the old filter dropped out when in removed the pan without me having to pull it out, I was able to remove O ring and replace with new filter & new O ring and was careful to get fluid level correct
there was a little fine magnetic sludge on the magnet but no chunks of metal
the car still does not shift at normal rpm’s/speeds
could this be related to T.V. Cable or bracket or is this some other issue?
any help is appreciated

Welcome to the forum.

Wait for a moderator to move this thread to the C4 forum for you.

Okay, looks like he's already got it there. Good luck with solving your problem(s).

You may want to try adjusting the TV cable.

Default shifting

my 93 does that too when the trans is cold, shifts from 1st to 2nd about 3500 rpm, 2nd to 3rd a bit faster. when the trans isn’t cold either air temperature or because it’s been running and now is warm it doesn’t do it
