Does the transmission need servicing?

Does the transmission need servicing? No where in my manual could I find info,one article I read on google said Mazda considers this a sealed lifetime component. Your input would be appreciated.

Welcome to the forum.

Just so you know, there are hundreds of discussions on this already which can be surfaced with the search of the forum or the internet more broadly.

Short answer: yes, it is recommended to change the fluid. There is no set interval, but some are using 30k miles.

Any transmission is a unit with metal-on-metal contact. Which is going to cause wear, over time. Under harder loads/conditions, the wear can be accelerated. No way to avoid that wear. Regular fluid changes are about the only way to slow the process.

Irrespective of what Mazda or any of a dozen other "top" car makers claim, there simply isn't a better way to slow metal-on-metal contact damage than to ensure proper lubrication. In addition to proper/reasonable use, proper adjustment, and proper rejuvenation of parts once they do wear to the point of impacting operation. Lubrication's downright inexpensive as compared to the costs of fixing worn transmissions, even if done every 30-50Kmi over the life of a vehicle.

Most owners appreciate that "lifetime" effectively equates to the length of time the manufacturer is on the hook for the warranty's coverage. End of life is the end of the last day of the warranty period, from the manufacturer's perspective.

Most owners "do the math" with those facts and decide accordingly.

My own vehicles: I ensure regular drive train fluid changes. Which on an AWD CX-5 includes the transmission, transfer case, and differential.

Well said.
