I replaced the rear transmission mount yesterday everything was fine.. Replaced front transmont today and engine shakes bad when In reverse or when AC is turned on...

Any ideas?
I am thinking anchor mount rubber is too hard...might have to get OEM..

 

Double check the torque on all fasteners, it could also be the engine mount is shot!

 

OK thanks I will check torque and engine mounts... Are the anchor/dea mounts bad quality?

 

Depends on what you bought and where, you state not OEM

 

I bought dea a3081 from amazon. Rubber seems really stiff

 

Is it rubber or polyurethane?

 

For the record; there is only one motor mount, it's the one on the top passenger side. It is what normally goes bad.

There is also a solid bracket tat connects the trans to the motor, that is sort of a trans mount.

Are you sure it's the mounts causing the vibration, not the trans?

 

I took out the dea a3081 mount and put back the original OEM mount and the shaking has stopped....

The dea mount is rubber but a lot stiffer than the drive tech mount that I replaced on the rear trans moubt..

I went to another place in the city that sells anchor mounts and its identical to the dea rubber..

So I either find a drive tech or an OEM

The drive tech mount I swapped out on the rear mount was identical in rubber composition and flexibility as the OEM minus the cracks that the old on had....when I changed that it removed about 95% of the shaking that was there before so in figured I would change the front one to remove the other 5%.... Well it all seemed good when I put the car into drive... Then when I put it into reverse it was really shaky.
Now that I put the old front mount back in its back to 95% non shaky....
