Title: torque converter bolts
Post by: chevn-up on September 25, 2017, 03:45:48 am: hey folks, trying to remove the torque converter from the flex-plate. This is an 85 TH350. My question is are these bolts reverse thread? I haven't been able to bust 'em loose yet.

Put a little more effort into and they will loosen just make sure you are using a six point so you don't round them off.

I think I have the numbers...... flexplate to crankshaft, 60-65 ft lbs. torque converter to flexplate, 35-45 ft lbs. and the transmission to the engine block, 25 ft lbs. Are these numbers ok?
