2 questions for the mechanics - The 1947 - Present Chevrolet & GMC Truck Message Board Network

#1 My torque convertor to flex plate bolts came loose (not enough for the nuts to fall off) and I tightened them. Now I have transmission fluid pouring from the front of the tranny. What did I break, how do I fix it. (TH350 tranny)

#2 One of the bolt holes on the front of my drivers side head for the alternator bracket is wallowed out, can I put a helicoil in it or do I need to tap it for the next size up bolt? (I also think the back two exhaust manifold bolt holes are in the same shape, I haven't pulled the manifold to see.)

Thanks, Krue

I don't know about your trans, but there is no reason you can't helicoil the bad holes in your head. No pun intended.

It sounds like you may have busted the front pump seal. You will have to pull the trans, take the converter out and then undo all the bolts around the front pump to get to the seal.

You may have pulled the welds on the thread blocks on the converter from being loose ,or used to long of bolts.

The convertor looks fine, and was full of fluid when I pulled the tranny.

Sounds like a front seal on the tranny is leaking.
