It was done because the truck had gone through three 4L65E's and kept breaking tail shafts and the owner wanted a real transmission

Note smoke from the back tires only and how the truck is starts to rotate and then straightens out







and yes that is how clean the truck was after we worked on it.

Clutch Pedal and Manual Transmission Brake Pedal



Shifter - a short shifter was made using part of the stock manual transmission shifter and a tie rod end to provide the correct geometry to shorten up the shifts. He hasn't finished up the custom console yet, but the cupholders willsitill fit and it will look stock when it is all done







Transfer case shifter. The handle needs to be modified so that it comes out on the outside of the center stack, but that is a no-brainer



The NV4500
