Ford 4R70W Rebuild

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.

4.6 3v is officially installed | Vintage Mustang 4.6 3V engine swap. After fighting with fitments the engine is in the mounts, headers on, oil pan on. H-pipe fits perfectly. Next is the transmission mount and shifter. Then the Vintage Air, power steering pump, and radiator.

Roof in Primer

So the Mustang roof got five heavy coats of urethane filler primer. Most of that will be blocked off to fill in the grinder marks left years ago by somebody that was in a hurry to paint it purple.
