This is the reverse lock-out unit for the New T-Maxx 2.5, and will also fit the T-Maxx .15. This unit is a forward only conversion for the T-Maxx.
COMMENT: I am utilizing this kit in order to convert old nitro tmaxx to electric. Reverse setup in stock transmission is not necessary with electric setup since rotation of electric motor will determine direction of vehicle which is controlled with Electronic Speed Controller ESC. by Javier I 3/10/2012
