#3 bearing thrust for lunch.

ok, the long and the short of it.

i have gone through 3 engines and two trans rebuilds.

the same thing continues to happen. my #3 main bearing thrust is being eaten away. the first time i didnt know it was happening until it scattered the engine. the second time i caught it and had different shop rebuild my tranz. now its happening again and the tranz shop says they have never seen this happen before. i need help to get this identifide and resolved i cant keep doing this.

at this point the only thing not changed out is the "heavy" tranz parts. the converter is different and the engine is different.

i did a test and found that as soon as i turn on the car the crank is moved to the forward position. neutral park makes no difference. next step is to unbolt the converter and see if the engine still moves forward.
