The 420G is a 6-speed manual transmission manufactured by Getrag. It is designed for longitudinal engine applications and is designed for use on engines producing up to of torque. BMW used this transmission with M60 V8 models such as the European manual 840i, European manual 740i, 540i;〔(【引用サイトリンク】 Part 23001222564 (RMFD-6 Speed Gearbox) )〕 as well as the M62 powered 5 series sedans, as well as S62 powered vehicles such as the Z8 and M5.〔(【引用サイトリンク】 Part 23007505869 (RMFD-6 Speed Gearbox) )〕〔(【引用サイトリンク】 Part 23007501757 (RMFD-6 Speed Gearbox) )〕 This gearbox was also used in the E34 M5, E36 M3, and E46 M3s with the S38B38, S50B32, and S54B32 engines respectively.〔(【引用サイトリンク】 Part 23001222697 (RMFD-6 Speed Gearbox) )〕〔(【引用サイトリンク】 Part 23001434507 (RMFD-6 Speed Gearbox) )〕〔(【引用サイトリンク】 Part 23002229721 (RMFD-6 Speed Gearbox) )〕 For the aforementioned applications there are three incompatible bellhousing boltpatterns: one for 8-cylinder engines (540i, 740i, 840i, E39 M5, Z8), one for the 5-series 6-cylinder engines (E34 M5, only for 1995), and one for the 3-series 6-cylinder engines (M3, 330i). It is unknown whether bellhousings can be swapped among them. The bellhousings can be interchanged between the E39 M5, E39 540I and the E46 M3. Among owners and mechanics, the transmission has a reputation for being strong, quiet, and routinely able to handle considerably more torque than its official rating. However, internal shift linkages are its one known failure point, and the real problem is that neither BMW nor Getrag will provide replacement internal parts (except some shift linkage parts), rebuild instructions, or rebuild service. The only solution to a failed gearbox is a replacement transmission.
