I found out i was getting knock due to my alcohol pump leaking FML. i fixed it now i did a couple knock free passes then my motor started to knock or thump in the lower back of the motor. the motor was a new block with all new parts. can it be tranny? any tips to try to diagnose whats wrong. hope its not bonn be a expensive fix

Loose converter bolts. I would check that first. Don't panic yet.

Once you do the check John suggests, cut the oil filter open.

I just spent like 6,000 fixing it. And my ally pump was leaking which was causing my knock now I have to tear it back out again.
