Custom transmissions for improved serviceability


Are you looking for driveline components for your custom built hot-rod or classic vehicle?  Consider Modern Driveline’s complete range of options for adding a five or six speed as your solution.  All parts from the back of the engine to the differential are available.  Many different clutch configurations optimize driving style and power level to your needs.


Our custom shortened input shaft TREMEC TKO-500/600 5 speed transmissions are direct coupled to the bellhousing/scattershield.  No spacer plate required.  Whether your engine is a y-block, big block, flathead, small block, Ford, GM, or Mopar we probably have a solution to connect the motor to the transmission.


Light Weight

Our recommendation for small block, light weight roadsters is the lightweight of the TREMEC T5z super duty transmission.  It is 25% lighter then the TKO’s, shifts smoother and also comes with the traditional shift location or a front shift position for a better experience.

High Performance Clutch

Our Dual Friction and Kevlar clutches are manufactured and tested to withstand the power of the engine and your driving style.  Our Kevlar clutch is the recommended solution for lightweight cars as the smooth engagement will eliminate chatter problems and the high wear factor means 2 to 3 times longer before a clutch change.
