CRP Automotive Pentosin ATF 134 FE Low-Viscosity Automatic Transmission Fluid — Blue, 5L, MB Spec 236.15 OE-Approved

Pentosin ATF 134 FE is a blue, low-viscosity automatic transmission fluid engineered and OE-approved to meet Mercedes-Benz specification 236.15 for 7-speed 7G-Tronic Plus gearboxes produced after June 2010.

This premium 5-liter jug from CRP Automotive contains Pentosin's latest ATF formulation developed to improve gearbox efficiency and low-temperature shifting behavior in compatible Mercedes-Benz transmissions. It is OE-approved (MB OE #001-989-78-03) and is specifically designed for the later-generation 7-speed automatics; note the blue color and noncompatibility with older red Mercedes ATF types.

How does Pentosin ATF 134 FE improve shifting and efficiency?

The fluid's very low viscosity reduces internal friction in the transmission, helping smoother gear changes and supporting potential fuel economy gains under certain driving conditions. Its formulation stabilizes hydraulic control at cold starts, preserving shift precision when temperatures are low.

• Lowest-viscosity ATF available for the approved Mercedes spec
• Engineered to optimize hydraulic control and shift timing
• Improves low-temperature pumpability and initial shift response

Which Mercedes models and years is this approved for?

Pentosin ATF 134 FE is OE-approved for Mercedes-Benz 7-speed 7G-Tronic Plus transmissions built after June 2010 under specification MB 236.15. It is intended for a range of C-, CL-, CLS-, and AMG variants produced across the 2010s where the manufacturer specifies the 236.15 fluid.

Can I mix Pentosin ATF 134 FE with older Mercedes ATFs?

No — Pentosin ATF 134 FE is blue and formulated for newer 7G-Tronic Plus gearboxes; it is not backward compatible with the older red-spec Mercedes transmission fluids. Mixing different-spec ATFs can alter shift quality and potentially affect warranty coverage.

• Do not mix with red-colored older Mercedes ATF formulations
• Follow vehicle manufacturer service documentation for fluid change
• Use the OE-approved fluid when topping or replacing transmission oil
