Watch your cruising RPM’s drop by as much as 36% while your driving pleasure goes up! The all new Tremec TKO-500 and TKO-600’s are high performance, true overdrive five speed transmissions. With torque ratings of 500 ft/lbs. and 600 ft/lbs. respectively, these all new Tremec transmissions are among the most versatile transmissions produced! In addition to the all-star line up of parts that we have assembled for our TKO kits, we have a commitment to offering the best, most responsive, and professional customer service & support you will find.

We specialize exclusively in Tremec TKO conversion kits for Classic Mopars and we have “walked the walk” by personally installing TKO’s into classic Mopar cars. Email inquiries are answered by the end of the day, we typically answer phone calls within three rings and you will always speak directly to one of the owners. We do our best to keep every part we offer in stock at all times and orders are usually shipped out within 48 hours.

We look forward to helping you with 5-speed Tremec transmission needs.
