The manual transmission line of Borg Warner is now owned (since 1998) by Transmission Technologies Corporation (TTC), however, the design remains unchanged between the two transmission lines. Borg Warner transmissions, for the most part, use a single rail gear selector and carbon fiber lined steel synchro rings, where the\u00a0TREMEC<\/i>\u00a0transmissions have a single rail that selects and moves three shift rods internally. These three rods have spring loaded detents that make the transmission feel notchy during shifting. Instead of carbon lined steel synchro rings, the\u00a0TREMEC<\/i>\u00a0TKO line is built with solid bronze synchros with no linings. It is for these reasons that the\u00a0TREMEC TKO\u00a0<\/i>does not like to shift well above ~6,000rpms unless modified.\u00a0 Carbon fiber rings are now available as well as several other modifications to improve shifting and durability.\u00a0 Contact us for details.<\/p>\n

New in 2004<\/h3>\n

TREMEC<\/i>\u00a0changed its line of TR-3550 and TKO in 2004. (TKO-500\/600 Press Release<\/a>)\u00a0 The TR-3550 was replaced by the TKO-500 and the TKO is now called the TKO-600.\u00a0 There were several changes in the new line up.The all new line of\u00a0TREMEC TKO<\/i>\u00a05 speed transmission are the most versatile, strongest transmission of the series.\u00a0 With eight available shift positions, three unique cross member mounting configurations, three available input shafts, optional gear ratios, dual electronic and mechanical speedometer pick-ups, neutral safety switch, and back-up light switch, this transmission does it all!How was this transmission improved?\u00a0 The 83mm center distance was maintained, and upgraded the counter shaft from a 3 piece to a one piece design.\u00a0 All the gears and shafts were upgraded to a higher alloy steel, while the aluminum shift forks were replaced with steel forgings and completely redesigned.The shifter has been upgraded to performance status with a unique adjustable biasing system to tune to your exact preference.\u00a0 Eight different shift locations means the shifter will likely fit in your stock console.The TKO-500\/600 features dual speedometer pick-ups, with both mechanical and electronic speed pickups.All cast iron shift forks for improved durability reducing failures with non-adjustable positive shift stops so it can not be over-shifted.<\/p>\n

New TKO-500<\/h3>\n

Ford TKO-500<\/b>\u00a0is torque rated at 500ft\/lbs. 10 spline input shaft with a 31 spline output shaft. 3.27 first gear with a .68od. Standard shift location is the rear “Mustang” shift point. Mid and front shift kits available. Main case bolt pattern remains the “toploader” pattern.<\/p>\n

\n

GM TKO-500<\/b>\u00a0has a 3.27 first gear with a .68od. Torque rating 500ft\/lbs. Standard shift location is the rear “vintage Camaro” shift point but can be changed to several other shift locations. Main case bolt pattern is a “Muncie” 4 speed pattern. Call for details.<\/p>\n

\n

New TKO-600\u00a0\u00a0<\/h3>\n

Ford TKO-600<\/b>\u00a0is torque rated at 600ft\/lbs. 26 spline input shaft with a 31 spline output shaft.\u00a0 Comes in two standard over drive configurations 1) 2.87 first gear .82od and 2) 2.87 first gear with .64od.\u00a0 Standard shift location is the rear “Mustang” shift point.\u00a0 Mid and front shift kits available.\u00a0 Main case bolt pattern remains the “toploader” pattern.<\/p>\n

Custom Configurations<\/h3>\n

TREMEC<\/i>\u00a0TKO transmissions can be shifted from three different locations. Front, Mid, and Rear. From the factory they are configured as a rear shift. To change the location, a mid\u00a0or front shift kit<\/span><\/span>\u00a0(front shifter is obsolete) are install and the rear shifter location is capped off with a provided plate.TREMEC<\/i>\u00a0TKO transmissions are a great replacement for Ford toploader four speeds or GM Muncie fours as they have been configured to bolt up to the stock bellhousings.\u00a0 Keep in mind that\u00a0TREMEC<\/i>\u00a0TKO’s are larger and taller then their 4 speed counter parts.\u00a0 We offer\u00a0TREMEC<\/i>TKO’s with a shortened input shaft that will bolt right in or if you only need the input shaft and bearing retainer give us a call. The only parts needed to convert from a three or four speed is a cross member, shift lever, shift ball, and shorter speedometer cable. The drive shaft length is not affected for the Ford conversion as the transmissions are the same length. The slip yoke may have to be changed to match the output shaft.<\/p>\n

Ford 3550<\/h3>\n

The Ford 3550 is a step up from a T-5z with 3.27 first gear and a .68od.\u00a0 Torque rate increased to 37
\n5ft\/lbs.\u00a0 The input shaft has the same 10 spline input shaft as that of a 93 and earlier T-5.\u00a0 The\u00a0TKO<\/i>\u00a0main case bolt pattern is different than the T-5 so a\u00a0TKO<\/i>\u00a0bellhousing is needed when switching out a T-5.\u00a0 The output shaft is a standard Ford 28 spline that has been used since the C4 automatic and toploader 4 speed days.\u00a0 Since the\u00a0TKO’s<\/i>\u00a0have the same bolt main case pattern as the early 3 or 4 speeds, it can be bolted directly to the 3 or 4 speed bellhousing when the input shaft is shortened to match.\u00a0 We offer both the shortened input shaft and bearing retainer as well as ready to install new shortened input\u00a0TKO’s<\/i>.\u00a0 Call us for details and\/or check our product catalog on-line.The 3550 has been replaced by the new TKO 500. See\u00a0New for 2004<\/i>\u00a0(above) for further details.<\/p>\n

GM 3550<\/h3>\n

The GM 3550 is designed to provide a five speed replacement to the Muncie four speed transmission.\u00a0 The input shaft and main case are ready to bolt to a four speed bellhousing.\u00a0 Input shaft is a 26 spline with a GM pilot. Output shaft remains a 28 spline so the slip yoke will have to be changed.<\/p>\n

Ford 3550-II<\/h3>\n

The Ford 3550-II is the same as the 3550 with a .83 overdrive.\u00a0 Great for road racing when the 1:1 ratio of a four speed is not enough and a .68 over drive is too tall.\u00a0 Works well for off roading as well in 2×4 trucks and SUV’s.<\/p>\n

Ford TKO<\/h3>\n

The Ford TKO transmission has the same layout and gear ratio as the 3550 but with stronger 26 spline input shaft and 31 spline output shaft and stronger 3rd gear. It is torque rated to 450ft\/lbs.<\/p>\n

GM TKO<\/h3>\n

The GM TKO is designed to be a replacement five speed transmission.\u00a0 However this time the output shaft is a 31 spline with the stronger 3rd<\/sup>\u00a0gear.<\/p>\n

TKO-II<\/h3>\n

The TKO-II is the same as the TKO but is equipped with a .83 overdrive instead of a .63 overdrive.\u00a0 Again great for road racing or off roading. Torque rating increase to 475ft\/lbs but has been known to handle much more.All four models have the same overall dimensions. The 3550-II and TKO-II are best suited for road racing where the .83 overdrive comes in handy on the long straight-a-ways. <\/p>\n
