SMG Solenoid O-Ring Set, MLR - E60 M5, E63 M6

This kit covers all shift solenoids for the SMG transmission in E60 M5 and E63 M6. If you have the transmission removed, and the solenoids are known to be functional - but leaking, this seal kit can help you rebuild them to be leak-free and operating at peak performance. Solenoids are electro-mechanical valves that control the flow of fluid within the transmission system, and over time, the seals on these solenoids can wear out, causing leaks, loss of pressure, and poor performance.

This o-ring set is provided by MLR Engineering - specialists in automotive hydraulics with over 30 years of experience. With vast knowledge of hydraulics, solenoids, pumps, and electric motors, MLR is able to provide solutions to common problems with SMG, DCT, and other systems. Factory repairs often involve replacement instead of improvement and that's the opportunity for MLR to provide better-than-OEM products and service.
