Tiptronic Pressure Regulator.
The Genuine Porsche Tiptronic Pressure Regulator 98632560300 is an electro-hydraulic control component installed inside the valve body of selected Porsche Tiptronic automatic transmissions.
Sold Each.
x3 Required Per Car.
Fits:
Diagram Ref No 8
Its job is to regulate hydraulic transmission-fluid pressure in response to electrical commands from the Tiptronic transmission control system.
Automatic transmissions depend on accurately controlled hydraulic pressure to operate their internal clutches and braking elements. By varying this pressure, the transmission can engage and release the appropriate internal components smoothly and at the correct time.
A worn, sticking or electrically defective pressure regulator can interfere with this process and may contribute to harsh gear changes, delayed engagement, slipping, irregular shift quality or transmission fault warnings.
Replacing a confirmed faulty regulator helps restore proper hydraulic pressure control and allows the Tiptronic transmission to perform gear changes as designed.
What This Product Does:
The Tiptronic Pressure Regulator converts an electrical control signal from the transmission-management system into controlled hydraulic pressure within the automatic transmission.
Its main functions include:
- Regulating automatic transmission fluid pressure.
- Controlling hydraulic pressure within the valve body.
- Supporting smooth clutch and brake-element engagement.
- Helping control gear-change quality.
- Supporting consistent transmission operation.
- Responding to commands from the Tiptronic control system.
- Helping maintain correct hydraulic operation under different loads.
- Replacing a sticking, electrically failed or mechanically worn regulator.
Symptoms Of Wear Or Failure:
Possible symptoms can include:
- Harsh gear changes.
- Jerking during shifts.
- Delayed gear engagement.
- Delayed selection of Drive.
- Delayed selection of Reverse.
- Transmission slipping.
- Engine speed flaring between gears.
- Irregular shift timing.
- Transmission remaining in one gear.
- Limp-home or emergency operating mode.
- Tiptronic warning indication.
- Transmission fault message.
- Stored transmission fault codes.
- Inconsistent shifts when hot.
- Inconsistent shifts when cold.
- Excessively firm engagement.
- Poor low-speed shift quality.
These symptoms are not unique to the pressure regulator and proper diagnosis is essential.
Why Replacement Matters:
Replacing a confirmed faulty Tiptronic Pressure Regulator helps restore:
- Correct hydraulic-pressure control.
- More consistent gear changes.
- Smoother clutch engagement.
- Correct transmission response.
- Reduced slipping.
- Reduced drivetrain shock.
- Proper Tiptronic control.
- Reliable automatic transmission operation.
