TC to flexplate issue

[ont_guy_38]

sounds like your converter has slipped out of the grooves , do not force it , take the engine back out and reset the convertor back in and hopefully the tabs on the tranny pump are not broken already,




K read it again and are the tabs that the bolts go through touching the flywheel?

No, there is a small gap between the tabs and the flexplate (or it looks like there should be, since they actually aren't even lined up. I had just finished bolting the trans to the engine last night and quit for the night without bolting the TC up.). Shining a flashlight between the TC and the flexplate, the only point of contact is at the crankshaft. The TC is seated fully - any further back, and the body of the TC would come into contact with the body of the transmission. There is only an 1/8th of an inch or less free space between the body of the TC and the transmission.

The nose is just too big, as near as I can see. The engine used to be mated to a TH350 before I swapped in the 700R4, so it can't be the crank.

I do recall seeing a yellow number marked on the TC when it was out - perhaps the PO put in a junkyard converter, so who knows what I've got now...

I think you are going to have to pull the engine back out and check your crankshaft hub;could be some corrosion causing a tight fit...is there any possibility there was a pilot bearing for a standard trans in your crank?

Pull the torque converter out and check it on the crank/flexplate;also change the torque converter front pump seal if you have not done so already
