My car is starting to vibrate pretty good on heavy acceleration usually above 3500 rpm. I could feel it vibrate in the rear and also through the shifter.

My car has 89k miles now. The motor mounts were changed with a major tune up at 85k.

Has anyone here have problems with transmission mount??

Please share any diagnosis... TIA

The weird thing is, it seems to only happen when the weather is hot.

At nights, it hasn't been happening.

I've ordered the transmission mount. So we will see if this get rid of the shake.

Anyone care to comment what transmission mount failure is like???

may be your suspension or the brushings. You may go through a little trial and error, but I'm far from an expert. I had a similar problem and the brushings cleared up 90% of the vibrations. Good Luck
