What does it mean when your transmission is slipping?

If you have a standard transmission, and it’s slipping—the engine revs but it doesn’t transmit power to the wheels—the problem is usually in the clutch. Further down in the article, I discuss how to diagnose this problem.

Can a slipping transmission be a solenoid problem?

Do not confuse a slipping transmission with a solenoid problem. You will hear and feel the difference when you try to shift. A slipping transmission will actually shift, but then not produce any power once in gear, whereas a bad solenoid will prevent the shift from occurring in the first place.

What is the trouble code for transmission control components?

The trouble codes for transmission control components begin at P0700, and the codes specific to the solenoids range from P0751 through P0758.

What causes a transmission to have poor shift quality?

Dirty fluid can cause all kinds of shifting issues because it clogs up small passageways going to the shift solenoids. If the fluid level is low, there’s not enough fluid to fill all these passages, and the transmission lacks pressure internally. This will lead to poor shift quality or no shift at all.

Can a worn transmission pump cause transmission slippage?

Worn transmission pump: The transmission pump supplies pressurized hydraulic fluid to the transmission. A pump that is damaged or worn can result in a lack of internal pressure and transmission slippage. You may hear a whining noise, or notice a fluid leak. Solution: Typically, the transmission must be rebuilt or replaced when the pump fails.

Why does my Buick transmission keep slipping gears?

Since modulators control shift firmness, a bad modulator can result in slipping gears. Buick’s T400 transmissions contain a plastic accumulator piston which often breaks. These pistons can be replaced by aluminum models in rebuilt transmissions. When in proper working order, this mechanism regulates engine braking, allowing for smooth shifting.

What are the problems with the Buick 4L80E transmission?
