millions, yes millions.

teh 4L60E tranny is the best auto tranny on the market for light duty vehicels. It can be found in ALL rear wheel drive 1/2 ton an lighter GM vehicles, yes ALL. That list includes fullszie pick-up turcks, full size SUV's, Corevettes, Camaros, S10's, Astro Vans, Fullszie vans, etc. GM has been putting them in these vehicels since 1980. Yes, 28 years in production and still going strong. Not saying they didn't have some issues with various model years, they did, however it is still the most reliable tranny on the market. To say this tranny is garbage is way off base. It has the best first gear and the highest overdrive gear of most auto trannies on the market. Not too mention it can be swapped from one vehicle to another without too much trouble. It can also be swapped behind a wide variety of engines too. No other vehicle manufacuter can make that claim, NONE.
