TCI Full Manual Valve Bodies

Get maximum performance and quicker ETs with these TCI full manual valve bodies. They're engineered to allow full manual control of the valve body, for quicker shift timing and higher line pressures. You get less clutch slippage under high load, so that more power gets to the ground. They're a great choice for bracket cars, monster trucks, and virtually any off-road competition vehicle where a transbrake is either illegal or undesirable.

TCI Trans-Brake Valve Body Kits

TCI trans-brake kits allow you to achieve maximum torque converter stall for quicker and more consistent reaction and 60 ft. times. They work like this: When the trans-brake is engaged, the vehicle can roll neither forward nor backward, and as you press on the accelerator, the engine can rev as high as the torque converter stall. Once the brake is released, power is immediately transferred to the rear tires, with less parts breakage than with a manual transmission.

TCI Replacement Steel Transmission Pans

TCI steel transmission pans are the perfect replacement for performance and appearance beneath your vehicle. These steel reservoirs are thicker than stock for longevity, and some models are beautifully chrome plated to further prevent rust—in addition to including a drain plug to facilitate fluid maintenance. Over time, many transmission pans develop a warped, leaky gasket flange, or become damaged by road debris. Protect your transmission by bolting on one of these economical replacement upgrades from TCI.

TCI Extreme Racing Starters

TCI Extreme Racing starters are engineered for racing and tight engine swaps where a smaller, lighter weight starter is desired. These starters are new, not rebuilt. They not only reduce front-end pounds for better weight distribution, but they will also provide extra room for headers, oil pans, and increased ground clearance as well. TCI Extreme Racing starters are built with full ball bearings for less friction and more torque, a heavy-duty contact disc solenoid for more consistent starts, and a high-temperature, epoxy-encapsulated armature to resist heat and vibration. Their efficient design draws less amperage, leaving more power for your ignition system to keep you in the race.

TCI PRO-X TH400 Aluminum Tailhousings

These TCI PRO-X TH400 aluminum tailhousings feature light weight and improved strength, while using a tailshaft roller bearing rather than the factory bushing for superior lubrication and durability. The OEM bushing is a common failure point with TH400 transmissions, as it can run dry in high-speed TH400 applications. The TCI PRO-X TH400 aluminum tailhousings are more rigid than other factory or aftermarket tailhousings, with increased structure for added support and durability. The use of the roller bearing provides added lubrication, and the usually unreliable paper gasket used to seal the housing to the transmission is replaced with a precision-machined surface that incorporates an O-ring for a solid, drip-free connection. Build a stronger transmission and have better reliability with one of the TCI PRO-X TH400 aluminum tailhousings.
