High Quality rebuilt transmissions are now available at Spotts Performance. All units are rebuilt on a one on one basis and tailored to your specific needs. I am only carrying Th400's and Powerglides for warranty reasons. We can also service your transmission .

My Th400 has performed flawlessly in the past 10 years, so I am confident supplying Pontiac owners with a strong and dependable transmission.

New! Super StreetFighter™ Transmissions

The TCI® Super StreetFighter™ transmission bridges the gap between our StreetFighter® series and our full Competition series transmissions. It is intended for normally aspirated vehicles powered by engines producing up to 600 horsepower. Like our StreetFighter® units, these are equipped with our 100% tested, Manual/Automatic valve body. That means that most units allow you to manually shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. In either mode, you get a racetrack shift that bangs through the gears and shaves time off your ET's. When you use the manual gear selection feature, the Super StreetFighterupshifts and downshifts right when you move the lever, with no lag or governor override. When you select the normal drive position, the transmission retains positive, automatic shifts for the ease of driving you look for in an automatic transmission.

Typical TCI® Super StreetFighter™ transmission features are Red Eagle® clutches, Kolene® treated steel plates, Red Eagle®-lined, extra-wide Powerbands™, larger diameter servo assemblies, an improved lubrication system, new sprags/roller clutches (upgraded in certain models), enhanced hard parts where applicable, chrome-plated, TCI®-logo transmission pan, increased thrust capacity, higher line pressure for extra firm shifts & greater torque capacity with less slippage, as well as being TCI® factory blueprinted, inspected and dyno tested.

Triple Tested Quality

TCI® strives to produce the best torque converters in the industry. Part of the process involves ensuring that each unit is built to spec. Triple TestedRegardless of what category or price level it may fall into, every TCI® torque converter is Triple Tested during assembly.

Once all the prep work on the component parts has been completed, the impeller is welded to the front cover. Immediately following this process, a pair of dial indicators are employed on a rotating table to verify that the impeller body and pump drive hub remain true.

Each unit is then pressurized and subjected to a leak test to confirm the integrity of all the weld seams. Lastly, each unit is computer balanced to reduce annoying and potentially damaging drivetrain vibrations that would occur from an unbalanced torque converter. That's Triple Tested so you can be confident you're getting a torque converter that's ready to roll.
