What is a PTU on a Ford Flex?
A PTU, or Power Transfer Unit, is an all-wheel drive (AWD) transfer case used in cars and sport utility vehicles, including the Ford Flex. It allows for power to be distributed to all four wheels either part-time or full-time, and it also varies how much power goes to the front and rear wheels based on specific driving conditions.
The PTU on a Ford Flex has been known to have some issues. It has a tendency to overheat and fail, and once it overheats, it cannot be rebuilt due to the damage that is done to it. Therefore, if the PTU fails, it needs to be replaced. Transtar carries new OEM PTUs from Ford for replacement.
Some Ford Flex owners have reported issues with the PTU, including thickened gear lube and lack of lubrication. To prevent PTU failure, some owners recommend changing the gear fluid frequently.
In terms of maintenance, while Ford does not specify a fluid change interval for the PTU, automotive experts suggest changing the PTU fluid every 30,000 miles for better PTU care. However, it’s important to note that this is not mentioned in the official Ford owner’s manual.
Overall, the PTU is an essential component of the Ford Flex’s AWD system, responsible for distributing power to all four wheels and adapting to different driving conditions. Regular maintenance and monitoring of the PTU’s fluid can help prevent potential issues and ensure optimal performance.

Can you drive with a bad power transfer unit?
That all depends on what is wrong with the transfer case. If low range went out but high range still works then YES you can still drive it. If the gears or chain went out then NO you can’t drive it. If the 4X4 part doesn’t work but the two wheel drive still works then you can still drive it.

The power transfer unit (PTU) is a device used to transfer hydraulic power from one system to another system without sharing fluid between those systems. The PTU consists of two axial-piston rotating groups, housed separately but connected by a common driveshaft and mounting adapter.
