Torque Converter ID


Recommended Posts

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

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.

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

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.

So does that mean it may be high stall modified or?

Yes, A high stall will be a modified one.  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"

My father informed me apparently the C6 never had a "high stall"T.C.  what are some details i should look for if it was modified?

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. Scan_2021_01_23_21_55_50_570_001.thumb.jpg.ca73df5b6b154c1c49018ed41fbbf97a.jpg
