Not sure of builder, JW told me when they went thru it, I remember it was a company out of Kansas. They said it was a very good converter. I took car into parking lot and was able to do 1st and 2nd gear burnouts while holding brake to add drag, everything seems to work correctly. Spoke to builder again and he assured me that auto trans don't work on chassis dyno's. Just looking for advice/confirmation.
Thx
