I have a john deere 302-A backhoe and everything works as should but I have no forward movemen. I replaced the main clutch and replaced the forward clutch pack the old one was burnt up. Changed fluid with new and still the same. The hoe won't go forward.I have a parts and service manual for the machine. But can't really figure out where to exactly check the pressure. Some one said that if the power steering is working then the transmission pump is working. But from what I've seen is the power steering works off of the main hydraulic pump not the trans pump. I NEED HELP BAD. The pics in the manual is not the best in some figures. So it's hard to tell.
