Years back I bought a PATC Raptor 200R-4 to replace the transmission in my 1986 GN. Before I bought it I had asked them multiple times if this was an exact replacement with no modifications necessary and they said it was. After being installed the mechanic said that there was an extra wire with no where to hook it up (auto OD) so right away being manual OD this was NOT a direct fit. To make matters worse the transmission would short shift at only about 3500 - 4000 RPM under full throttle. Under part throttle it would shift through the gears and be in drive by 35 MPH. PATC sent me a new governor and it made no change. My mechanic also adjusted the TV cable which only made a minor improvement. Due to other problems with the car and health problems the car has sat with limited use. I'm trying to get it ready for this summer but I have no clue how to go about getting a new auto OD valve body and governor that will match up with PATC's set up. PATC has been no help saying they don't carry these valve bodies.
