Fabricating a transmission tunnel for any race car, street machine, classic truck or hot rod can easily be accomplished thanks to new kits from Chris Alston’s Chassisworks. Available for both manual and automatic transmissions, the kits feature pre-formed 18-gauge steel panels that are tack-welded in place.

Designed to accommodate popular transmissions, like the Tremec Magnum T56 or General Motors 4L80E, the 35˝ long tunnels can easily be shortened for tighter fits on other transmissions. The tunnel height is intentionally tall to provide adequate transmission room on vehicles with extremely low ride heights and can be trimmed if necessary.

The bellhousing diameter for both is 22.1˝ and the tunnel can be positioned to fit an existing firewall opening and also trimmed. To carry it further, complete firewall kits are available from Chassisworks, as are floorboards, driveshaft tunnels, wheel tubs and rear flooring.
