This is a 2000 Mustang GT 4R70W transmission . It is going into a 1966 Mustang with a 4.6 3V. I rebuilt this with a stage 3 kit. It got high energy discs, a shift kit to repair the factory line pressures, repaired the EPC failure problem, all new seals and bushings. A 2200-2600 stall convertor to handle the loping idle from the Comp Cams. The electronics will be controlled by a US Shift Quick 4 controller. The controller came with a plug and play wiring harness. The shifter is a Lokar unit very good quality.
