Product Information
A complete service kit for when your BMW's 6HP26 transmission Mechatronic unit is removed from the transmission, including required replacement seals, filter/pan assembly, fluid, and hardware to complete the service.
Mechatronic issues are the most common source of performance problems in the 6HP transmission. The most basic issues start with the seals between the Mechatronic unit and the transmission body. Leaks or defects in these seals can cause pressure loss, resulting in shift quality problems.
More advanced issues stem from the Mechatronic unit itself, with solenoid failure and electronic problems being relatively common. Addressing these problems requires removing the Mechatronic unit and replacing all seals.
This kit is designed to handle everything from basic Mechatronic servicing to complete replacement. All hardware, seals, and filter/fluids are included for a comprehensive 6HP26 Mechatronic unit service.
Transmission Service Kit
The transmission oil filter prevents harmful particulate matter from entering the transmission valve body, protecting bores, solenoids, and fluid passages. Contaminants can cause shifting issues like delayed shifts, harsh shifts, or even no gear engagement. A clogged filter can reduce fluid flow, leading to transmission pump starvation, often indicated by an RPM-dependent whine from the bell housing area. The transmission oil filter should be replaced during any fluid service and is critical when major transmission components are replaced, such as the torque converter, transmission pump, or valve body.
Transmission Service Kit Failure Symptoms:
Whining noise from the transmission pump
Driveability and shift quality issues including harsh shifts, delayed shifts, or no gear engagement.
