Getrag 260
Overview
Manufacturer	Getrag
Production	1984–2005
Body and chassis
Class	5-speed longitudinal manual transmission

The Getrag 260 (RPO M35) was a 5-speed manual transmission incorporated in BMW and General Motors vehicles between 1984 and 2005. It coexisted in the market with the lighter-duty Getrag 240, and more expensive Getrag 265 models.

Note: While some of the internal components may be interchangeable, GM units (transmissions from Holden and Cadillac cars) are not interchangeable with those from BMW cars. Two distinct versions of the integral bellhousing were used by BMW, depending on the associated engine (either a BMW M20 or BMW M30), with additional minor variations to accommodate different flywheels and engine management systems.

The Bentley BMW 5-series E34 Service manual declares the oil capacity of the 260/5 and 260/6 transmissions to be 1.25 litres. Manual transmissions installed on the E34 are normally filled with Dexron III Automatic Transmission Fluid (DX3 ATF), though alternative fluids may be used depending on shifting effort and gear noise.

Some 80W-140 oils promote themselves as a suitable alternative where DX3 ATF is specified by the manufacturer.
