98 GTP tranny slipping?

I havent been around in a while but since i got this car in sept it would slip a little between shifting. what i mean is it would go in first then "slip" before it hit second i would notice it more when i wasnt on the pedal alot when i put the perf shit on it seems a lil better but im not sure witch way to go with this any suggestions? also the car is under used car warrenty from the dealer does anyone know about these warrenties i have a $100 dollar deductable so can i make a list of stuff thats wrong with the car and pay $100 or is it $100 for each thing i want fixed?

Use that warranty ! You do not have to use the dealer,most repair shop's will do extended warranty work.

Hey, um I have the exact same problem with my GTP. Ever since the tranny fluid/filter was changed, my car seems to not wanna shit when its under a heavy load. At little throttle opening, it seems to be fine. But when i floor it, even if im in Performance shift, it doesnt want to shit when it hits redline. It'll just sit there for a second then shift, which is not good! i do have extended warranty, but i would like to know what's wrong before i take it into the shop. Any help would be appreciated!

Do all these GTP's need an EX-LAX in the tank? They all seem to have trouble Sh@#ting! :grinno:
