46re torque convertor and flexplate question
This is my first post!
I have a 97 dodge SST project truck. My issue is it came with a rebuilt trans in it, but had a vibration.
long story short is the flexplate had no weights on it...
The torque convertor bolt circle matches the original flex plate but is diffrent from the 5.9 flexplate that I purchased.
Do I need to change the torque convertor? Or can I open up one of the holes?
thanks for the help. MB

Yep. The 5.9 is externally balanced, prior to 96, the balance weights were on the torque converter, always struck me as passing strange..... For the 96 model year, the torque converter was neutral balance, and the weights moved to the flex plate. If you can get a part number off the torque converter, wouldn't hurt to look it up, and see what year truck it was designed for.
The bolt spacing also change, along with the location of the weights. With weights on the TC, it was important that it was properly indexed.... 96 and up, it didn't matter any more, so the bolts are equally spaced. It's possible that you got a flexplate on there for a 5.2 liter, and not the 5.9.....

Cant' read 'em that well, 'cause of the glare.... (and my vision ain't the best anyway.... )
But, if it bolts to the 5.9 gas, it is highly likely to be the correct trans.
If you like the stall speed of the tc you have, just get the right flexplate, with the weights, and stick it back together. So far as I know, the plate with the weights on it, *should* have equally spaced bolt holes for the tc...... as there is no reason for it to be indexed, since it doesn't play role in engine balance any more.
