    Product Description

    112005 B&M Extreme Performance Off-Road/Race Automatic Transmission - GM TH400

    1965-2003 Chevrolet Small Block, Big Block, LS, and GM 4.3 V6 engine, 2-Wheel/Rear Wheel Drive - SFI Certified Bellhousing. B&M Performance and Off-Road introduces the new Rock/Race GM TH400 Automatic transmission specifically designed and built for Off-Road competition. The foundation starts with a tough and tested Reid Racing Super Hydra 400 Off-road race case and SFI 30.1 certification bellhousing that fits all Chevrolet 90 degree V8's including early and late LS engines and 4.3L V6 engines. Upgrades include a new super tough 300M (Rockwell Hardness) alloy steel 30 spline input shaft, 34 element direct drum and a wide Intermediate band for increased engine braking capability, strength and performance. Other features include a Billet 1045 alloy steel forward hub with bearing, four friction Intermediate clutch pack and a Reid Racing tailhousing with roller bearing providing superior support for the 32 spline output shaft. The forward pattern manual valve body has been re-calibrated to ensure constant pressure, quick shift response and provides engine braking. The transmission is finished off with a B&M Hi-Tek finned aluminum trans pan which both increases fluid capacity and quickly dissipates heat generated by tough off-road race conditions. Handles up to 900 HP/900 LB/FT 1965-2003 Chevrolet Small Block, Big Block, LS, and GM 4.3 V6 engine, 2-Wheel/Rear Wheel Drive - SFI Certified Bellhousing *Can be used with 4wd transfer case with tail-shaft modification
