So I bought a torque converter off a board member a while back that he said was a restalled D5 to 2800. I've had it sitting in my garage for a while now and was going to install it. I looked at the stampings...and it just has a 6 stamped all the way around it. Does that mean there's no way this could be a restalled d5? Is there any way short of installing it and brake testing to find out what the converter actually is?
