Can a clogged filter cause a torque converter to whine?
A restricted or clogged transmission filter makes the same whining noise as a faulty transmission pump. It’s crucial when diagnosing a transmission pump or a torque converter.
Why does my GMC transmission not go into gear?
Transmission will not go into gear when warmed up gears t… I put Lucas in the transmission because it was low on transmission fluid and was slipping in over drive then it stopped working at all after I put Lucas in it but when I first start it will go into gear and work fine until I get up the street then lose all gears how can I fix this
What kind of oil pump does a torque converter use?
Transmission oil pumps provide fluid pressure for the transmission and torque converter. The valve body regulates, controls, and directs the flow of pressurized transmission fluid. Gear and rotor-type are considered fixed displacement pumps. Most pumps today are variable displacement.
What kind of pressure does a transmission use?
The transmission uses fluid pressure to shift the gears, and does so using electronic solenoids. If there is an issue with either of these the vehicle may experience problems shifting or transferring power to the wheels.

Why are the bearings in my torque converter worn out?
A widespread problem is that the bearings in the torque converters are worn. This does not cause slippage or other transmission problems but can cause bearing noises from the transmission. If you hear bearing noises from the transmission, check the transmission fluid, and see if you can see metal parts inside the transmission fluid.
Where does oil come from in a torque converter?
When the torque converter control valve is stroked, oil comes from the manual valve, to the 3-4 shift valve, back to the torque converter control valve, then to the neutral drive accumulator and forward clutches.
Can a slipping torque converter wear out the transmission?
A slipping torque converter will wear out the transmission very quickly. In some cases, you may have temperature sensors that cause the transmission control unit light on your dashboard to flash, which indicates that your torque converter is slipping and overheating the transmission.
How does a torque converter affect a transmission pump?
It saves energy by reducing output without affecting speed. Transmission pumps are driven directly from the engine through the torque converter. The torque converter housing is mechanically attached to the engine’s crankshaft causing the pump to operate whenever the engine is running.
What causes a zero turn hydrostatic transmission problem?
Zero turn hydrostatic transmission problems can start with air in the system, a condition known as cavitation. When the pump is full of air instead of oil, it can’t generate the pressure needed to provide power.
How to diagnose a problem with your transmission?
Diagnosing a transmission is the same as anything else; it often ends up being a process of elimination. Make sure it’s not a problem with the engine before troubleshooting transmission noise or vibration. Begin with the basics, and remember, if something is not moving, it’s not making a noise.
