buzzboy said:Not sure if it helps too much but a Jeep AX15 and a Toyota R154 are the same transmission as the AR5.
The AR5 (imho) is a really good transmission. It supposedly can handle big horsepower. It shifts crisply with very positive engagement. Only real mod I had to make to mine (which came out of a Colorado) was to the shift mechanism to bring the shifter forward to work in the tiny Bugeye Sprite cockpit. Very simple mod; basically I scrapped the entire external shifter, and built an adapter to drop straight down into the transmission. Then curved the shifter forward (a'la the old Cobra's). Works great.
