I understand there is a torque converter lockup conversion available for the C4 or C6 auto trans. I looked a C6 over on the bench and it is possible except for the torque converter. One would have to be found or made with the lockup in it.
Anyone know of such a thing.

 

Moved to proper forum.

 

Never heard of lockup in any of the Cx transmissions. Nor can I think of anyway you could get the trans to apply a locking torque converter.

I think the C5 had a mechanical lockup converter. I have also heard that maybe B&M is making one for the C6. I can't find any info on that tho.
