Tremec Parts / Upgrades
The Tremec TKO-500/600 5 speed transmissions are descendants of the Ford 4-speed "top loader" transmission released in 1964. Ford decided to get out of the manual transmission business in 1973 and sold the tooling and manufacturing rights to the top loader and 3.03 3 speed transmission to Tremec in Mexico. Both of these transmissions and their derivatives were built for many years and found in many vehicles around the world. Tremec developed the 3550 by adding a 5th gear, tapered roller bearings and caged needle bearings under the mainshaft speed gears. This unit was originally designed for truck applications but was modified to fit the 5.0 Fox Mustangs in the early 90's. The TKO was introduced in 1994. It has the same gearset and material (8620) as the 3550 but larger input and output shafts. The purchase of BorgWarners manual transmission business in 1996 brought the 4615 technology to Tremec. This material is extremely tough and greatly improves the impact strength of a transmission. The 3550/TKO Road Race units introduced in 2002 used 4615 steel in the cluster and mainshaft 3rd gears. These transmissions were well received in the marketplace but had very limited sales due to the .83 road race 5th gear. For 2004, Tremec is producing a new TKO line with 4615 steel gears (wide and close ratio), cast iron 3 pad shift forks, dual speedo pickups (mechanical and electrical) and high performance shifters. Tremec claims that prototypes have been successfully drag tested at 600 lb-ft engine torque. Existing 3550/TKO units will be phased out of production as the new units come on line (approx. 3/01/04).
