Hi! And thank all of you how created and keep updated this discussion!
Yesterday night I installed TransGo Shift Kit on my Buick Terraza 2005 4T65E. Before installation it had hard shifts 1-2-3-4 even and converter lockup when transmission hot! Plus
lot of chatter (shaking the dashboard chatter) at star. Of course I visited local transmission shop (this shop has best review on all websites, at local cars care places and auto parts stores) for quote and diagnostic. The owner of the shop was really nice and gave me range $2250-3000. I spent 120$ (TransGo Kit, Filter, Fluid) to fix almost all issues!! But I still having small problem: Sometime trany give minor kick at start. Guys do you have any suggestion how to fix it?
