Bert LMZ Aluminum Transmission

Unlike Bert's linkage-shifted Gen II line, the LMZ builds its clutch right into the case, pairing an internal hydraulic clutch assembly with dog-tooth gears for quick, positive engagement. IMCA accepts it for Modified, Stock Car, and Late Model competition, and this listing is the bare transmission rather than a bolt-in kit. Why racers pick the LMZ over Gen II The compact aluminum housing, shorter than a Muncie case by roughly 2-5/8 inches, can ease fitment in a tight chassis, and the internal clutch removes the need for a separately shifted linkage setup. High gear is still direct drive at a 1.00:1 ratio, and the output end accepts ordinary GM Muncie, Saginaw, or Powerglide slip yokes rather than a one-off style. What you're buying here This listing covers the transmission, its internal hydraulic clutch assembly, a front bearing retainer, and the dog-tooth gear set; a bellhousing, shifter, and slip yoke are each sold separately. Dry weight runs about 48 lbs over roughly 19 inches of overall length, with the same 600 lb-ft torque capacity found across Bert's lineup. Common questions Does it come with a bellhousing? No, that's a separate purchase, along with the shifter and slip yoke. What yokes will fit? Standard GM Muncie, Saginaw, or Powerglide styles. Normal racing use and correct installation are the conditions behind Bert's 1-year limited warranty on materials and workmanship.
