I am putting a 4L80E into a 1986 K30 4x4 6.2 NA diesel with a TH400/NP205. I am looking for a stock GM computer for a 91-93 6.5 turbo diesel in order to control the 4L80E. Does anyone have any insight on this swap? Any spare controllers out there? I have the 4L80E from a 94 Suburban 454 4x4 and pieces of the wiring harness. Does anyone know if the torque convertor from the 94 Gas Suburban will work acceptably on the diesel? Is the flexplate that's on the diesel going to work for the 4L80E? I know that I have to put a TPS on and get a 40pulse VSS signal from the Trany or transfer case. Any help would be greatly appreciated. I know that I can buy transmission controllers from aftermarket sources but I don't have the money to go that way.
