Maybe you guys can help me figure out my issues.
Every 2004r that i put into this car I end up cracking the pump rotor. Last time I had the transmission rebuilt I ended up shattering the rotor after about 725 miles. At first we thought it was a problem with the flexplate so we purchased a new one, and it does not seem to be any different from the old one. (As far as warpage) the old one does not have any cracks either. We checked the thrust on the crankshaft, and there is nothing wrong there.
The first transmission that it broke was the original transmission, I got that one rebuilt, and the same thing happened to it. And it happened again a third time. So I purchased a high performance transmission with a non locking converter, and it quickly cracked the pump rotor in that transmission, so I took it to be rebuilt, not long after that I ended up shattering the rotor. Luckily the builder warrantied that rebuild, and now I have the car back on the road. But for how long?
There is sometimes a knock coming from the transmission once it warms up, not always but sometimes. I am completely stumped as to what it could be.
Any ideas no matter how crazy they are will definitely help me out, I have no idea what to check at this point.
Sorry for the long post but I am trying to get as much information as i can on here. Let me know if you need more information to help me diagnose this problem.
Thanks in advance!
