When putting truck in reverse the wheels lock
Pressure at reverse and forward test ports reading 100 psi each
No brake work was done to suggest them locking up
Acts as if the drive gearbox goes into park
Will studder in reverse if rev engine but not move to far
Checked inching brake and is set correctly
Truck moves slightly forward in neutral position
Removed and replaced gasket on valve body for shift spools
Am at a loss for what to check next
Does anybody have an idea?
