This is a Lenco Hi-Gear only transmission. It is not a 2 speed. The transmission case has the big shaft that goes through the case to make it high gear only. The reverser is in good shape. Been sitting so some new seals would be a good idea. Comes with a reverse shifter. Pretty sure this is not the big sprag reverser so no blipping the throttle in reverse! If you are running an altered it is needed to have the front case so that the drive shaft won't be so long. If you were to put the reverser right on the back of the bellhousing and you have a car where the engine is out 60" or more then the driveshaft would be impossible. I decided to go to upgrade to a 2 speed because I won't have enough HP to pull direct drive.
