i have a hydro b16 tranny s4c gears are grindless, case is great. only problem is the differential gear is mess'd up. I was limping on this tranny for roughly 2 months until i saved up $$ to buy another tranny. So was planning on gettnig this one rebuilt but I have no time for it no more but not planning on giving it away neither. I was in great running order, but somehow the diff just gave up or something and starts skipping on the teeths on the passenger side axle when theres alot of load on the tranny. Like say going up hill or pedal 2D metal lmk
