I'm happy to say that I just replaced the a833 18 spline 4 speed in my 70 V-Code Track Pak Roadrunner. I am taking a 90 mile trip tomorrow to a shop to look into going from my 3.54 to a 4.10 gear for my Dana 60. The short ride I've taken so far has me very excited about the a855. The shifts are very solid and precise. The synchros work great. The best thing so far is that I went from 3500 RPMs @ 75 mph to 2250.
Thanks Jamie for all you do for the Mopar community and for your outstanding and one of a kind, unequaled, exceptional a855 transmission. My car isn't numbers matching, if anyone-ANYONE-has a classic numbers matching 3 pedal car and wants a 5 speed, the a855 is the ONLY choice. I chose it for its outstanding specifications, build quality, choice of components and materials. I am very excited about the trip tomorrow. Having a .70 final gear and dropping 1250 RPMs is great and makes driving on the highway a much much more enjoyable experience.
