- Harsh, erratic or slipping shifts
- Transmission pressure alarms
- Gear remains engaged or will not engage
- Contamination, internal leakage or sticking valve spool
🛠️ Service Notes
- Work clean and cap ports and pipes as they come off — a control valve is a close-fitting part and grit is what kills it
- Find out why the old valve failed: contamination, water or degraded fluid will take the new one out just as fast, so check the fluid and the filters at the same time
- Renew the O-rings, seals and gaskets that come with the valve, lightly lubricated with the system fluid, and make sure the ports and seal faces are clean
- Tighten the valve and its unions evenly to the figures in the workshop manual for your engine or drive; overtightening distorts the body and can make the spool stick
- Refill and bleed the system to the manual's procedure, then test function at low load first and check for leaks and correct operation before normal use
