One of the most overlooked bearings in these 5 and 6 speed Getrag 440 and Getrag 446 transmissions is the input shaft bearing in the end case. This bearing is opposite of the bellhousing bearing that contains the throwout bearing collar.
This bearing is responsible for supporting the input shaft on the end case side and a failure in this bearing can lead to exacerbating the famous “Getrag Rattle” these transmissions are known to do at idle in neutral and also lead to poor shifting and eventually major damage.
This bearing is somewhat hard to obtain as it is not a typical bearing part number that has many crossovers. We have this bearing available as a kit, including new bolts, on our website here.
Bearings in a transmission are not something that should be installed blindly. There are pre-load or endplay settings that must be correct to assure long life, good shifting, and a quiet transmission.
In the following video we will explain what bearing endplay or pre-load is and why its important to set this up correctly. We will walk step by step throughout the process of setting up the bearing endplay and installing your end case input shaft bearing.
We also offer shims for all of the bearing races for these transmissions here.
