Automatic Trans Shift Improver Kits

Have you ever wondered why the shift in your car seems "doey"? The answer is simple; the average driver in the average car does not like to feel his car change gears.

The result is that the factory builds in slippage between gears, providing a nice subtle shift. However, when you want your car to launch, this results in wear and heat build up as well increasing your ET.

An APC billet servo upgrade will eliminate that. We fine tune the hydraulic control settings and provide a smooth but firm shift under normal driving conditions and solid, rapid shift under load.

You will increase your gearbox life and reduce your ET accordingly.
