ThugPug98 Posted January 28, 2021 Share Posted January 28, 2021 I have a "new" C6 tranny that came with what I was told was a high stall converter. I removed my current believed stock converter and I can't find any Identification on the outsides of either one. They look similar but there is a difference in weight after I drained them. Could I get a little help please? I found codes inside on one of the gears that was the same in both which was "cpmpc c5tp-7926-B2" The "new" converter came with a orange ish red mark on it while my current one has a black and a separate green mark. I have found a PDF that shows torque converters of all kinds for all kinds of cars but I can't really find any that fit my situation Link to comment Share on other sites More sharing options...
Oldtech Posted January 28, 2021 Share Posted January 28, 2021 Can you tell if the converter in question has been cut apart and re-welded. Compare the welds around the outside. If it is a high stall it will have been cut apart and modified. if it looks factory... probably not. Link to comment Share on other sites More sharing options...
ThugPug98 Posted January 28, 2021 Author Share Posted January 28, 2021 I noticed the weld around the part that slides into the tranny on my OG T.C. has a more apparent weld around it and cleaner but that isn't much to go on. In the first picture, the top one is the OG Link to comment Share on other sites More sharing options...
Oldtech Posted January 29, 2021 Share Posted January 29, 2021 (edited) The weld in question is the one around the outside rim. Probably just behind the "step:" They cut them apart in a lathe to modify, then reweld in the lathe so looks pretty pro.

If it's never been apart it's not likely. There are of course different ones for different stock applications but none are what I consider " high stall" Link to comment Share on other sites More sharing options...

Oldtech Posted January 30, 2021 Share Posted January 30, 2021 I agree with father! Look closely at the outside weld. You may be able to tell if it has been cut and redone, or possibly a second weld where there isn't one on the stock TC. Link to comment Share on other sites More sharing options...
