My 89 GTA seems to be shifting funny all of a sudden..It takes more RPMs to get it to shift gears...Anyone have any ideas?

 

check the fluid and filter, adjust the tv cable

 

Exactly, if you need instructions go to the tranny board, do a search and follow transfixleo's method.

 

is it a 700r-4? if so have you changed the tranny fluid lately?

every single time i change my fluid it starts slipping.everytime!!!i change it every15000-20000miles without delay everytime it will slip for about a week or so! this time when i changed it at 40,000 miles its slipping AGAIN! and this time its saying goodbye im going out!!!!700's suck shlong!!

 

arent 700's just wonderful? I love overdrive and the first gear ratio, but the reliability on the is very iffy, their biggest problems are either going to complete trash, or burning up from heat, check fluid level and pull the pan and look for tiny shiny metal chips

 

Thanks for all the responses guys!
Drove it to work today and it was fine.Shifted normal..
Last night I did a doughnut around the parking lot at work,and thats when it started acting up..May be I stretched the tv cable or something..Tranny fluid is full and only has about 9000 miles on it..
