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.

It had just rained a little so you will notice a few drops on the hood scoop
After many months of anticipation I finally took the 66 Mustang on it’s maiden voyage. about a 3 mile round trip. I never got over 3 grand or out of 3rd gear about 60 miles an hour at one spot. The car was never more than 1/4 throttle. I got some grabbing of the clutches in the posi the last part of my journey. I also had some chatter from a tailpipe tapping on the fuel tank. Other than that I think it went very well for the fact that the car is pretty much completely re-engineered. I will figure out the rear differential problem I am hoping Heidt’s didn’t assemble it wrong and change up my tailpipe hangers. Then I will take it to the next level on a test drive.
