for the past two year's 340 has had a multiple speed transmission. last year we worked on the
Dr. Joe DeWalt XRP transmission (read
this for suggestions on how we suggest how do it) while this year we went with the Andy Mark two speed. we find them very useful to the games an love having them. if you need help with the design or anything like that let me know. i have helped out the students with the designs for mounting, custom plates, and other components during both of the years.
