Thanks for the reply John

I have taken the overdrive section apart and cleaned the whole thing out. It looks to be in real good shape. The person I bought the tranny from said it had been removed from a truck back in the late 50's and just sat around for all these years. It was missing the speedo gear and when I took it apart there was sand in it, mostly in the overdrive area, no wear to speak of all gears look to be in excelent shape. I have been driving this truck for the past three weeks with this tranny and it is real tight. I will set up a cable, I purchased one on ebay but to short to use. I will set up a switch and see how the overdrive works. If I like it as much as I think I am going to, then I will look at other options of setting it up. Drive train wise the only other thing i will need is to change is the rear end gears. I currently have the original 3/4 ton 4:57 would like to find the 4:10 out of the 67 to 72 3/4 ton with automatic. Then the drive train will be trully ready for any type of driving.

Thanks again
Steve
