Shell ATF 134 Automatic Transmission Fluid for Mercedes-Benz — 6 Qt Pack (MB 236.14 / 236.12) — OEM‑spec shift stability

Shell ATF 134 is a fully formulated automatic transmission fluid engineered to meet Mercedes‑Benz MB 236.14 and MB 236.12 specifications, supplied here as a convenient six‑quart pack for routine service.

Designed by Shell—an established name in engine and driveline lubricants—this ATF 134 formulation is tailored to the needs of many Mercedes‑Benz automatic transmissions that call for MB 236.14 or MB 236.12 fluids. Each bottle holds 946 ml (32 fl oz), and the six‑count pack brings enough fluid for multiple drains or a multi‑vehicle shop, making it practical for owners and mechanics who prefer OEM‑compatible fluids.

Which Mercedes transmissions accept this Shell ATF 134?

This fluid is suitable for Mercedes automatic transmissions that specify ATF 134 or list MB 236.14 or MB 236.12 approvals. It is intended to match the friction and hydraulic properties those gearboxes require for consistent shifting behavior.

• Compatible with transmissions citing ATF 134, MB 236.14, or MB 236.12.
• Meets viscosity and friction characteristics needed by specified Mercedes units.
• Useful for owners following Mercedes service intervals and fluid specifications.

How much fluid comes in the pack and how should I use it?

The package contains six individual 1‑quart (946 ml) bottles, providing 5.676 liters total—enough for many routine services or partial refills. Use one bottle per fill point as directed by your vehicle manual; always verify capacity for your specific transmission before topping off.

• Six bottles × 946 ml each, total ≈5.676 liters.
• Pour from the bottle into the transmission fill or service port according to manufacturer procedures.
• Check dipstick/level indicator and follow recommended warm‑up checks to avoid overfill.

What performance attributes should I expect from this Shell ATF?

Shell formulates this ATF to provide stable viscosity and controlled friction characteristics under a wide range of operating temperatures. That helps maintain consistent shift feel and hydraulic function in transmissions designed for these specifications.

• Stable viscosity over temperature ranges typical for automatic transmissions.
• Designed to preserve intended clutch friction behavior and shift quality.
• Packaged in accurately measured 32 fl oz bottles for clean, controlled pours.

Can this fluid be used in other vehicles or mixed with other ATFs?

Use this Shell ATF 134 where Mercedes‑Benz MB 236.14/236.12 approvals are specified. If you consider mixing with another fluid, consult vehicle manufacturer guidance—mixing different formulations can affect friction characteristics and is not recommended unless explicitly allowed.

• Intended for transmissions listing ATF 134 or MB 236.14/236.12 approvals.
• Avoid mixing unless vehicle documentation permits compatible ATF blends.
• When in doubt, perform a full fluid change to a single approved product to ensure consistency.

Who is this for: This six‑quart pack of Shell ATF 134 is aimed at Mercedes owners, independent mechanics, and small workshops that service Mercedes‑Benz models requiring MB 236.14 or MB 236.12 fluids. It suits anyone who wants measured, brand‑backed transmission fluid in convenient single‑quart bottles for accurate pouring and multiple service intervals.
