When torque converters first transitioned from the early bolt-together units to the welded/sealed units of the present day, transmission shops were faced with a new challenge. Most customers weren’t willing to pay for a new OEM converter on top of the cost of a transmission overhaul. The only alternative available at that time – reusing the customer’s original converter – seldom saved the customer or the transmission shop any money. More often than not, reusing the original converter created new problems when contamination from the original failure entered the newly overhauled transmission.
