Rebuilt 904 w/ tf2 shifting woes...

When in doubt; disconnect the trans linkage at the carb, and just tie the KD lever all the way back; then go for a ride. Until you internally adjust something, this will produce the absolute crispest/fastest/hardest shift, and at the highest rpm,that the trans is capable of delivering, in it's current set-up.Make sure you can feel the spring-resistance.
Oh yeah, wind it out some...
