I have an 01 GTP it has a 3.5 pulley and a CAI, thats it. The trans started spewing fluid, come to find out the bearing on the end of the diff was wasted, so I bought a used trans threw the diff and cover in the car and am back driving.
When taking apart the used trans it seems that it was just rebuilt. everything looks good, so im just going to put it back together install it and have the one in the car as a backup. My question is what are some good upgrades that i should put in this trans since its out and apart? I dont want to spend much over 500 for upgrades, I dont race the car, just beat it as a daily driver. I just wonder what are some common fail parts that I should replace now.
Thanks
