Vibration over 40 mph.

[winstoninwisc]

Just a hidden problem cause the slightest vibration and took out my tourqenverter seal ,blew out fluid and smoked my $3000.00 transmission. How would you guess it was paint thickness away from the tourqenverter sitting flush at the back of the crank and some 1 tell me what they see , how would you know ? Or am I missing something . Crank bolts all same thickness heads, no washers , flex plate straight flat, tourqenverter bolts all extremely tight. Read this bolt pattern in the paint and wonder how or y , give me your best theory, then. Be careful, don't know how any1 would ever think this ,but here it was I hope. Can't afford to loose the next tranny on something I can't see

Got pictures of those bolts?
Got a picture of the flexplate?
Got a picture of the washers that were under the head of the bolts?

 

[winstoninwisc]

No I don't but will take , no washers used in the crank or flex plate , don't know why it was cocked on . O did start a new thread to try to find some1 who may also experienced this hidden problem

Was the balancer smooth like a 318 and 340 or was it like the 360s?
