Disadvantages of the Ford B6 Plus gearbox
- This is a relatively new transmission, and there’s very little information about its failures yet;
- The only weak point of the transmission so far is the front input shaft bearing;
- There are also complaints on specialized forums about the rapid wear of the first-gear synchronizers;
- It’s very important to monitor for oil leaks, as the oil sump capacity is small;
- These transmissions are also known for their dual-mass flywheel, which isn’t the most durable.
