Bert Transmission 1400 Gen II Aluminum Standard Transmission

Listed under SKU SG-1400, the Bert 1400 is the Muncie-length edition of Bert's Second Generation aluminum circle-track gearbox: its tailhousing runs 3 inches longer than the short case so it sits correctly in a chassis already built around Muncie dimensions. Complete, it weighs 37.9 pounds.

Why the extra length matters

Bert designed the Second Generation line to cut rotating weight by roughly half versus earlier transmissions, and this version's shifting-clutch hardware is meant to speed up getting in and out of gear during a pit stop. Since the tailhousing matches Muncie dimensions rather than Bert's shorter case, measure your current driveshaft and mounting points against that length before buying.

Rounding out the driveline

The gearbox ships on its own; Bert's matching shifter is sold separately and does not come bundled with this listing, so budget for that piece if your current setup does not already have one. Confirm your track's class rules allow a Second Generation unit before racing it, since not every sanctioning body permits the same gearbox styles.

Q: Does this replace a shorter Gen II case directly? Only where the chassis is built around Muncie-length dimensions; a car set up for the shorter housing needs that version instead.

Q: Does a shifter ship with this transmission? No, Bert's own shifter is sold on its own, so budget for it separately when planning the rest of your driveline.

Bert markets this gearbox for circle-track classes including IMCA, UMP, and USMTS modifieds, plus late models and street stocks, wherever a given track allows it.
