Hi, about two years ago we purchased a stage 3 (Keisler 4L60E) automatic overdrive for our A body Barracuda to go behind a Keith Black Hemi...the transmission works so good, it should be illegal!!

Mike Joslin 1968 Dart GTS

 021 Mike Joslin, OH, 1968 Dart GTS, 426 HEMI, 5-Speed: This was our third Keisler 5-speed kit, and as usual, it worked flawlessly.  We got Keisler's new carbon fiber pistol grips, and the interior had an awesome look.  We drove this car from Ohio to Niagra Falls, NY, then to Mopar Fest in Canada and back.  It would not have been possible without Keisler's kit.
