I've got a 92 firebird with 700r4 tranny. here recently it's been taking longer to shift from gear to gear (higher rpm's). Now it's to the point that I it needs almost 400 rpm's to shift no matter how much or little gas you give it!!! Anyone have a clue as to what the problem might be? Any advice would be greatly appriciated!!!

 

What is the condition of the fluid? Is the fluid level correct? Have you checked the TV cable to see if is adjusted correctly?
