Shell ATF 134 & 134 FE (MB 236.14 / 236.15)

Get the right Shell ATF the first time

Automatic transmission fluid isn’t “close enough.” Mercedes specs matter—especially when you’re dealing with 7G-Tronic / NAG-family transmissions. This collection is focused on the two Shell fluids most commonly required:

Shell ATF 134 — MB-Approval 236.14 (also referenced as the replacement for fluids listed under MB 236.12)

Shell ATF 134 FE — MB-Approval 236.15 for NAG2FE+ fuel-efficient 7-speed applications (distinct blue fluid for quick visual confirmation)
