Aisin makes great transmissions in Toyota and Komatsu forklifts. With all the fwd/rev slamshifting a forklift gets put through, I would trust them in a truck. They are a HUGE Japanese company. Several componets on the Japanese forklifts are made by Aisin, including water pumps, fuel systems (diesel, gasoline, propane), hydraulic controls and of course the transmissions. They have been around a long time and have a good reputation from my aspect of the business.
