I may need a new transmission soon so I have been doing some research. There are two different NV4500's. They go from 1991 to 1996 and then 1997 and up. Does anyone know what the difference is. Does one have a better input or output shaft and would I be wise to put a newer style NV4500 in my truck.
Thanks,
Justin

 

That one I would like answered also. I love the throw on the 98 5 speed.
