The hydraulic pump has to make the directional change. you have a problem with the new pump.

I will have the levers pushed forward it may go 6 ft forward and then it reverses while levers are still forward so you are saying the new hydraulic pump is bad?
Mechanic: Curtis B., Technician replied 9 months ago

The change has to be made in the pump, it directs fluid to each motor, and from what I gather, there are internal problems in the pump, allowing to oil to go to the other direction port.

The only part not new is a block that attaches to top of pump that has 2 switches attached to it one is for temp other is for pressure
Mechanic: Curtis B., Technician replied 9 months ago

The new pump is the problem!  Call your supplier and get another pump.
