RVS · Jan 20, 2016

I have a770A road grader that we are working on in class. Apparently the power shift tranny is the same as used in some tractors of the same timeframe. Anyone have any ideas what tractor would use the same tranny. The information I have is
8 speed forward 4 reverse. power shift Component serial number TOTP848001910X

thanks for information

What issues are you having with it ??

The free online parts book will cross reference any part to any other application where it is also used.

It wont pull itself ahead in any gear Only will start to move and then jump out of gear it seems like. if you feather the clutch it will sometimes hook up for a short distance ,but releases when it hits a grade or any load.

How long since hyd filters were changed & sump screen checked/cleaned? Next thing to do is check trans pressures in all gears.

no idea about filters .this machine was bought at auction. Will check these out Monday. I heard that I needed to check pressures but cannot find out anywhere to get the info from. (I know , get a service manual)I am working on that now just would like to get started on this before it comes. thanks for the Info
