Hello guys,
I was visiting with JohnnyB the other day and we had a conversation that was about fuel mileage and that you could get a little more if you had a lockup torque converter. Last night we were trying to narrow down which year vehicle has these T.C. but could determine it.

Does anyone here know what year donor vehicle I should be looking at to get a lockup torque converter?
