hello, i have a 2008 mazda3i manual with 130,000 and wanting to change the transmission mount but cannot find what is the torque spec.

what is the transmission mount torque for the one under the battery? the four side screw and the one in the center.

Another question: the torque for the motor mount (under the car). Some say 54-66 ft-lb for the 2 bolts for the mount and the 3 bolts for the bracket that mounts to the transmission are 70-85 ft-lb. is this right?

thank you

 

There are two different centre bolts used by Mazda, there may be a "8" or "10" on the bolt head.

"8" 83-113nm
"10" 130-152nm


The four corner bolts are 44-61nm

 

Thank you for the info. What about the one under the car. Is it sound right, 54-66 ft-lb for the 2 bolts for the mount and the 3 bolts for the bracket 70-85 ft-lb and should i use any thread lock blue or red on these as well?

 

The bracket that bolts to the gearbox is 65-75nm

The bolts thru the actual mount can varry between cars, refer to picture.
