ok! can anyone tell me whats wrong with my car? i have a stock 99 gst auto. when im cruisin ( lets say 60 mph) and i decide to slow down, the car at times feels like i just dropped it into the "LOW" gear. it bogs down until give it more gas. and then on top of that, sometimes when i try to accelerate at what ever speed, i can hear the t-25 spoolin its heart out, but i dont feel the acceleration. whats going on? what could it be?

The tranny might be having some issues. I will let Tony answer those questions since he basically has the same car as you.
