The pump, built into the front of the transmission, is driven by the torque converter when the engine is running. When the pump turns, it creates a vacuum that pulls fluid from the pan through the filter.
What causes transmission pump failure?
The presence of debris and dirt in the transmission system causes problems for the pump. Once the pump inlets and outlets are blocked, the transmission will begin to slip. You will notice that after engaging the gears, they will have trouble staying in one or more positions.
Can a transmission pump be replaced?
Automatic transmissions require transmission fluid to power the hydraulic system, and a transmission pump is what moves that fluid around. When the transmission pump becomes clogged or broken it needs to be removed and then repaired or replaced in order to prevent more serious damage to the transmission itself.
What does it cost to replace a transmission pump?
The price range for an automatic transmission front pump is between $110-350 and make sure that all the connections will match up. Visit websites and research on the automatic transmission front pump that needs replacement. Check all the part’s characteristics and model number before making a purchase.
What happens if the transmission oil pump slide spring is broken?
When your pump starts failing, the fluid in the pump will obviously not be circulating into the transmission like it’s supposed to. As a result, the transmission will begin to overheat and the fluid will burn. … This symptom can also happen when your fluid levels are too low, so make sure first that this is not the case.
How long do transmission pumps last?
But generally speaking, you should be able to get at least 150,000 to 200,000 miles of life out of a transmission, if not even more than that. It’s not all that out of the ordinary for some transmissions to last for over 200,000 or even 300,000 miles.
What does a bad transmission pump sound like?
Noise: A failing transmission pump will often make a whining noise. Because the unit is driven by the engine, the sound usually increases as you accelerate. Transmission slippage: Transmission fluid is used to change gears as you drive.
How do you fix a transmission whine?
Whining and/or noise whenever the car is moving. Sometimes the sound is paired with the gears slipping. This usually indicates damaged fluid or a low fluid level, and can be fixed by changing the transmission fluid. If the fluid checks out, the problem may be the pump.

Will a transmission whine in park?
If you hear a whining noise while your vehicle’s transmission is in park or neutral, it could very well be caused by worn needle bearings inside the transmission’s torque converter. If these bearings wear out, the transmission will begin to have trouble shifting.
What type of pump is used in the transmission?
Generally, gear pumps are used in open center hydraulic systems. Gear pumps trap oil in the areas between the teeth of the pump’s two gears and the body of the pump, transport it around the circumference of the gear cavity and then force it through the outlet port as the gears mesh.
How do you know if your transmission cooler is bad?
You hear odd noises coming from the transmission: Your transmission may have difficulty shifting between gears, or there may be clunking or grinding noises during shifts.
