Repairing a Broken Stud - Not for the Squeamish

[Jacques Reed]

Hi Lionel,

I have virtually no knowledge of automatic transmissions but the link below may help answer your question. I assume it is an older C4 or C6 transmission in the truck.

I'm thinking replacing it with a rebuilt torque converter might be the safest way to go after reading all the posts.

Hello Jacques,

Thank you for finding the posts Jacques - it is much appreciated.

Having read the word from the technicians I might follow a third option. Sell the engine with the gearbox - without a torque converter - as a free part of a job lot.

For no extra cost, not only do you get the engine; you get the main section of a gearbox too!

In the meantime I will cast a casual eye over different wreckers stock - just in case a second-hand one comes along. If that does not happen - well it is just too bad, how sad.

It was good to read that the nuts on the torque converter studs are finicky and give other people trouble too! I am not Robinson Crusoe with the nuts - which brings a bit of consolation to me

Kind regards
Lionel

Hello All,

After taking advice from this forum I looked at some more alternatives. I found a business that sells re-manufactured torque converters. They accepted my converter with the mangled studs as an exchange - without having to pay any extra. So I now have a factory rebuilt torque converter to fit to the gearbox.

I also bought a set of new nuts to fix the torque converter to the flex plate.

That was an expensive introduction to the area of automatic gearboxes!

Kind regards
Lionel

Lionel, good call. If a torque converter gets out of balance it can create all kinds of havoc with your transmission and even your engine. Not that a couple studs re welded into place would do that but you never know. New or rebuild units come prebalanced so all is well

I would suggest using blue Loctite on the studs and of course torque the nuts with a torque wrench. I cannot count how many loose torque converters I have seen over the years, and the elongated holes they make in the flexplates.
