I just got my transmission back from the shop. [stock th400-pontiac] Before I loaded it up to take it home I noticed it has a 6 bolt hole torque converter not the normal 3-hole torque converter that I’m used to seeing. When I ask the mech. if he have given me the wrong converter, he tell me "oh that’s a better one- it for a heavy duty trans. and will work-better than the others"
So did I just get sold a bill of goods or is this guy for real?
If this torque converter with 6 bolt holes is ok, and I only install just the normal three bolts (out of six) to the flywheel(3-hole) will this converter knock without having all six bolts installed and tighten?
Will this style converter still be/have the stock stall speed? Is there any why to cheek the stall speed before I install the trans.?
Or do I just wait on the tran's install and get a more familiar and trust worthy converter, like an after market(tci, b&m )? What’s a good stall for a highway cruiser that sees less than 5000 miles a year with 400 motor and stock gears and tires?
I know I have asked a lot of questions, but I really don’t want to reinstall this transmission more than once!
