Hey Guys, I'm currently working on a 57 Dayton Brown van w/ a four speed Hydro. This one is water cooled/heated via a heat exchanger located in the fluid pan. wow... I'd like to find the specs on this tranny w/ fluid type and amount as well as any filters etc that may be involved in changing the fluid. The owner tells me that the tranny wants to go into 3rd to early and I'm thinking that the fluid is bad in that it does not slip just shifts early. Do these trannys use vacumn anywhere? I don't see any vac lines. Also do the clutches work like motorcyle clutches in that there is no torque converter. Lots of questions about these guys. Thanks Doug
