Car Product Specifications      Service_Manual

This five-speed overdrive transmission was developed using state-of-the-art technology and is ideal for specialty sports cars equipped with high torque engines.

Features:

  • Five forward speeds with 5th gear overdrive provides extended ratio coverage, lowering engine RPM's and improving fuel economy. (Available in .68 or .82 overdrive ratio)
  • Tapered roller bearings on input, output and counter shafts increase torque capacity.
  • Massive 83 mm center distance from mainshaft to countershaft allows for the largest most durable gear sizes. 
  • Specially designed aluminum die cast housings provides optimum strength-to-weight ratio.
  • Steel input shaft retainer enhances durability.
  • TKO models are offered with upgraded steel on select gearing, delivering maximum torque capacity.
  • Internal multi-rail shift linkage system provides robust, positive shifting.
  • Fifth speed synchronizer located on countershaft reduces gear rattle and shift effort.
  • Multiple shift lever locations available:
    • Rear - standard on all TR-3550 transmissions - ideal for Mustang applications
    • Mid-shift location - ideal for pick-up truck retrofits
