Hello I would like to discuss today what it means when you get a fault code for transmission gear monitoring faults. For example a common one is 4f85 or a 4f8C. These are common in the ZF HP 6 19,21 and 26. for the E-clutch failure.

The transmission will go into fail safe, that will put the transmission into limp home mode and keeps it in 5th gear which ends up burning up the E- clutch and you will get a gear monitoring fault. This means that the input shaft and the out put shaft have a difference in ratio. Most BMW or German repair shops will just replace the transmission with a rebuild or a junk yard trans.

We here at Cooper & Bimmer Experts will rebuild your transmission for usually half the price and will give it a two year unlimited mile warranty.

So if your in the Los Angeles area come give us a visit, you won’t be disappointed¬† 626.963.6333
