I noticed it pushed some fluid out the filler hole and then it would not go into gear, nor would it take fluid. I found the pump shaft twisted and broken. I have gotten another one but would like to know what caused this. If anyone could advise me on this i would appreciate it. I don't have alot of experience with automatic trannys. The transmission is a 4t80e.
you put the studded bolt for the trans mount bracket in backwards. short end goes into the casting, not the long side. i did this once...
