<VV> too much trans fluid causing an ominous knock?

[Shaun McGarvey]

Hi Jedd, the transmission thing is normal, the engine thing is not.
The "knock" could be a number of things, but with the accompanying loss of 
power, a lot fewer things. When you did your rebuild did you reuse the 
original pistons? They have a habit of breaking at the oil ring groove 
causing the top to come right off. If it's not that, I'd bet on a dropped 
valve seat.
So do a compression test before you pull the engine. My guess is you'll find 
one hole with zero and only have to pull one head off.

yea, Vairily ... Shaun
