hello. i need some help please. i have a 2000 gtp. trans fluid was bad, so i flushed the fluid, changed the filter. took about 9 quarts. maybe 9 1/2. the car drove nice when first done. i drove it easy. i ran around the house for a minute, made sure it was full. then i got on the freeway. i knew my fourth gear was stripped already one of the reasons for the flush, i knew metal was in the fluid. i get off the freeway and drove south on gratiot. mind u i was driving easy. i stopped at almost every light, got about 4 miles and i felt the trans shift out way too fast. well it tripped me out. so i prayed lol. my destination was a mile away, i stopped again at a light, took off slow, i saw the tach do sumthin which looked like a slip, also it shifted out way too fast. i got to my destination, it was pouring rain. wasnt sure if it leaked or what.i kno when it get so low i will loose a trans and this was not the case. i let it sit for about two hours, still raining. get in the car and drove all the way home. non express way. it drove fine. the next day i get in the car and of course now i have the windows down. i hear a WHINE only when in gear. reverse, and drive. in nuetral and in park the noise is gone. i checked fluids, it was fine. i checked engine codes, and oops it has a tcc stuck on code. so i figure that the tcc stuck on and the line pressure was increased due to the tcc fault. so i left the pos batt cable off for like 8 hours. hooked it back up and no change, the whine in gear only. so i been driving it and it doesnt miss a beat. so maybe i am thinking a clogged or restricted flow somewhere. if anyone has any help i would apriciate it. sorry it is long, i am just trying to explain it perfect. i even added lucas trans and altho i believe in the stuff and seen it work esp in fords......no change to mine. sometimes it seems like the noise wants to go away but trust me it is not going away. am i resetting it right with the pos batt cable off or? if there is something clogged i drove it high idle, i think it would have cleared. any way to back flush so it uncloggs? do i try to re change the filter maybe its plugged or obstructed?? im lost. it shifts fine, it even shifts smooth not hard. ever. any help? i am desperate befoe i damage this beyond repair. i already know i was tearing it down to replace the fourth gear....i rebuilt the engine like 2000 miles ago, and i didnt find one thing wrong with the engine except for high miles. i just dont like the idea of having to do both the engine and trans. but i feel this trans is still good. if u made it though this i commend u lol. thanks guys in advance. mike.
