OPGI is proud to offer these TKO 5-speed conversion kits from American Powertrain. Whether you currently have a 4-speed and are looking to drive your classic A-Body more and maximize fuel economy on the highway, or are looking to do an automatic transmission to manual transmission swap, we have the kit for you. With 3 different transmission kits to offer, we have something that will guarantee to meet your exact needs. American Powertrain has developed these transmissions with maincase streamlining. What this means is that you are minimizing or completely eliminating transmission tunnel modifications but will also allow the use of the original transmission crossmember. This ensures that your vehicle will still retain the original look and feel of your chassis and interior but giving you the convenience of having a modern overdrive transmission. Add your bellhousing, clutch and linkage and your driveshaft and you are ready to slam gears in your brand new 5-speed transmission. Not only do these transmissions give you tire shredding light to light performance, but you can also slide into 5th and cruise down the highway getting noticeably better fuel economy. These modern overdrive transmissions are essentially the best of both worlds! Each TKO transmission is rated up to 600 ft.-lbs. of torque and will handle anything you can throw at it. The TKO500 features a 3.27 1st gear with a .68 OD ratio, the TKO600RR is perfect for those vehicles looking to do some road race events with a 2.87 1st gear and .82 OD ratio, and last but not least the TKO600SS features a 2.87 1st gear with a .64 OD ratio.

Each kit includes: AP Revolution offset shifter mechanism for OE 4-speed shifter position, cryo hardened steel driveshaft slip yoke with 1330 style u-joint, mechanical speedometer conversion, VSS wiring harness for electronic speedometer or fuel injection, reverse light wiring, transmission mount, steel roller pilot bearing, shift knob, hardware, detailed instructions and warranty information.
