I replaced the filter, powerflushed the trans, checked for debris. Nothing noticeable when I look at it. It sounds like a bad rod knock but its coming from the torque converter. There is also a bare metal stripe around the outside edge like something is rubbing it but the noise only appears when the engine is warm and strain is on the trans. I.E. when driving only. I checked the flexplate bolts and everything is torqued properly. No shimmy or shake or vibration, just that damn noise! If I drive it for more than 20 minutes with the knocking then the truck stalls out when I hit the brakes. Fuel pressure good, timing good, injector pump good too. It's an ex military CUCV M1009. No shop wants to look at it because its ex military and totally different from civilian but a trans is a trans. Motor is different but trans is not.

I take my 85 full size blazer to the Summit area for mud fun about every other weekend. Im tired of pulling puny little jeeps out of the mud. My truck has a 8 inch lift with 44 inch tires and a 3 inch body lift. I want someone who can keep up on their own
