Most Common ZF6 Transmission Problems/Repair Costs/Fluid Change

Last Updated on November 1, 2022 by Robert Wilson

The ZF6 is a six speed manual transmission that was built by ZF Friedrichshafen. It has been used in a variety of vehicles, including the BMW M5 and the Chevrolet Corvette. The transmission has been known to have some problems, however, which can lead to expensive repairs.

One common issue with the ZF6 is that the input shaft Bearing can fail, causing the transmission to make a grinding noise when it is shifted into gear. This problem can be exacerbated by high mileage or improper maintenance. Another issue that has been reported is that the gears can become stripped, which will cause the transmission to slip out of gear or not engage at all.

This can be very dangerous and is typically caused by excessive wear on the syncro rings. If you are experiencing any of these problems with your ZF6 transmission, it is important to take it to a qualified mechanic for diagnosis and repair.

If you’re having problems with your ZF6 transmission, there are a few things you can do to try and troubleshoot the issue. First, check the fluid level and make sure it’s full. If it is, then the next step is to check the filter and make sure it’s clean.

If both of those things are in order, then you may need to have the transmission flushed and refilled with fresh fluid. Finally, if none of those things seem to be fixing the problem, then you may need to take your car to a mechanic or Transmission specialist for further diagnosis.
