This transmission build service is recommended for the 3S enthusiast wanting THE ultimate gearbox. This Dog Box uses racing gear-engagement style dog teeth instead of conventional synchros, which allow for quick and definite gear shifts. This transmission can easily be driving on the street as well as abused on the track! The gears that are equipped with the dog teeth are 1st thru 4th only. The 5th / 6th / Reverse gears use the stock synchros.

The 1st gear has straight cut teeth. The 2nd gear has a reduced helical teeth. The 3rd and 4tf gears are stock. Unlike most racing Dog Box transmissions, this transmission is absolutely silent in all gears except the 1st. First gear does not whine, but it sounds pleasantly entertaining. The gear box uses the original H-pattern shifting mechanism making this transmission is absolutely streetable.
