tci-maximizer 4×4 Transmissions 211400

The TCI Maximizer 4x4 Transmissions 211400 is a remanufactured three-speed automatic with a straight automatic valve body rather than the manual-override design used on TCI's StreetFighter line, built on a Chevy bellhousing pattern with a 2.48 first gear and a 30-spline slip-on input.

Fitment and build

Match the Chevy bolt pattern before ordering. The case is OEM-style aluminum finished in black, the pan is steel finished in chrome, and fluid fills through the case. No horsepower rating is published for this model, and TCI does not list it as lockup compatible or trans-brake equipped, which fits its role as a daily-driven rebuild rather than a track-only unit.

What to budget for separately

Source your own torque converter and flexplate, add a controller and wiring harness, and plan for a cooler, dipstick, and fluid, since none of those accompany this case. This is a remanufactured unit sold individually rather than new, built around the same forward shift pattern used across TCI's automatic lineup.

Can this be shifted manually like the StreetFighter line? No, the valve body here is a standard automatic design, without the manual-override feature built into TCI's StreetFighter transmissions.

What bellhousing pattern does it use? Chevy, so confirm your engine and bellhousing combination matches before buying, along with the 30-spline input on the converter side and the stock-style steel pan clearance underneath.
