Whats the odds of the shop installing a New TC thats defective? They had the tranny reinstalled & during the test drive said the TC was bad & has to be pulled again. No extra cost other than the delay.

 

Any part can be defective, but quality/brand, new/rebuilt of part used is most important. Some one on here just recently had a rebuilt TC go bad. Have them put a quality new one in, not a rebuilt unit.

 

There are no new ones, unless you buy a new truck.

Any converter you buy (unless its a completely billet custom made converter ($$$$$)) is going to be "rebuilt".


To answer the op, yep, Ive had freshly installed converters go bad on the test drive.

 

HUH? So if I was to order a new TC from PATC lets say, are you telling me it's a rebuilt unit?

 

Pretty much. They start with the old converter core, cut it open and remove all of the internals.

Depending on who is rebuilding the converter will depend on what they put back in it. A quality stock rebuilder will clean and inspect all of the internal parts, do the necessary updates (converter clutch, return springs,ect), and address the problem areas associated with different converters. Weld them back up and balance it.

The specialty places will go in and may replace the stators, have custom impellers or turbines, replace bearings, and other hard parts. In some cases you may get all new internal parts, and many now have "Billet back" converters. They cut the converter cover out of a solid piece instead of stamped steel, the billet holds the lock up clutch better under severe conditions. Also they will weld new hubs onto them.

Ok, thanks for the info Monte.

 

If the TC was bad should the tranny be rebuilt again? Doesn't a bad TC release metal and other crap into the tranny?

 

Yes, And I only know that from one of MonteC's replies in a different thread.

 

Usually yeah. Unless there is just a problem with the lock up clutch. They would just tell him its a bad converter.

Ive had a couple that we have installed just **** the bed with in a few miles, metal everywhere, pretty much had to re re build it.

 

Welcome back monte !
