Fruita CO | It shouldn't do that in the time it takes to shift gears-all syncro's will do that, the trans pump stops when the clutch is disengaged. If it quits that soon, you have:
1-trans pump is worn out.
2-A line or o-ring is blown off the pump, or other leak in the low-pressure circuit.
3-High-pressure leak to sump in steering, brakes, rockshaft or SCV. If it's a side console tractor it can be in the PTO valve.
4-Plate on the bottom of the rockshaft housing is cracked or loose.
5-possibly an internal leak in the main pump, but not likely. | |
