lolol. they invited the clutch for a reason. just kidin. i've been through 2 and then i bought a t-45 and sent it out and had it proshifted. its costly but they tranny is less likly to go out. you can get a Brand new, not rebuilt t-45 for your car for 1000$ from a place up in michigan. let me know if your interested and i can get you the number and shit.if you do change it, put an alum. flywheel and drive shaft in it. it will rev lots faster and you'll notice a difference. probably get about .30 off your times but you have to stay with a low gear, such as 4.10 4.30 or 4.56.
