U asked and i quote, "what is the best mod to get for a 4R100?" So i gave you the best mod. Nowif you would have asked how would a Valve body work, then i would have given a positive opinion on that as well. A built transmission would be the BEST mod, but a valve body would work fine too.WHAT ABOUT A VALVE BODY??? What's that all about. i'm looking for mileage and pulling power when i'm not worried about the fuel mileage
Regardless of what you say...FUNNY. These transmissions are seemingly hit or miss. Yours will fail shortly, mark my words. Its an unfortunate truth we must all accept.not funny. I don't abuse it and I haul tractors with it all the time. I do actually change the oil & filter on a regular basis. I have no problem with it.
