PerfectFit™ has many benefits and addresses many concerns regarding the installation of a Tremec TKO into your classic car, street rod or classic truck.

PerfectFit

  • Shifter location
  • Shifter stub angle and height
  • Driveline angle
  • Transmission tunnel clearance
  • Additional required parts for installation

Shifter location - not all cars have the shifter in the same place inside the car.  PerfectFit™ provides over 15 unique shifter positions that will satisfy any requirement of your build. Custom variations are also possible with your supplied measurements.

The PerfectFit™ shifter mechanism is compact and requires little clearance to fit. The shifter action is tight, crisp and has a short throw.  It detaches easily for transmission installation and re-attaches without the need for re-sealing. 

Shifter stub angle and height - no knuckle busters here. Every shifter stub has been engineered to duplicate the factory shifter handle angle and height for a clean installation.

Driveline angle - Each package has been engineered to maintain the driveline angle specifications. You'll enjoy smooth highway driving with no vibrations.

Transmission tunnel clearance - Every PerfectFit™ model receives custom case machining to eliminate or greatly reduce tunnel modifications. If tunnel mods cannot be eliminated, we supply you with a guide on how to modify your tunnel along with a pre-engineered and ready-to-use patch panel that can be welded or riveted into place.

Additional parts required for the installation - this covers other items that you probably already have but will not be compatible with the Tremec TKO. This is referred to as an installation kit.
