Mazda Premacy automatic transmission forward piston
The forward piston plays an important role in the Mazda Premacy automatic transmission and is responsible for transferring power from the engine to the transmission gears.
Features and Function
*Material: Made of high strength aluminum alloy.
* Shape: It has a cylindrical shape with a head that interacts with the torque converter.
* Function: The forward piston creates fluid pressure in the automatic transmission hydraulic circuit, which activates the clutch pack and engages forward gear.
Design
The forward piston consists of several main components:
* Piston head: Connects to the torque converter and transmits fluid pressure to the clutches.
* Piston housing: The cylindrical part of the piston that moves inside the automatic transmission housing.
* O-rings: Seal the gap between the piston and the body, preventing fluid leakage.
* Piston spring: Returns the piston to its original position after the fluid pressure is released.
Malfunctions and symptoms
Faulty forward piston can result in problems shifting gears or lack of vehicle movement. Common signs of trouble include:
* Difficulty shifting gears to forward gear.
* Slipping or complete loss of movement in forward gear.
* Vibration or noise when shifting into forward gear.
Replacement
Replacing the forward piston is usually required if it is severely worn or damaged. This is a complex task that requires specialized tools and knowledge, so it must be performed by a qualified mechanic.
Service
Regular automatic transmission maintenance, including fluid and filter changes, can help prevent forward piston failure and extend its service life.
