Unhappy Car shakes when downshift from 2nd to 1st

I have a 98 CL 3.0 152000+ with original Auto transmission

My car shakes when downshifting from 2nd to 1st if I foot off the gas fast sometime
and acceleration is slow in the first two gear while I am using D4


With D3, there is no shaking and acceleration is great

I have changed the spare plug and transmission fluid

Also, the gas mileage is bad; I got only 15 per gallon

Any suggestion?

Tranny mounts. At that speed you have a lot of kinetic energy moving forward and along with the weight or mass of the tranny the mounts have a tendancy to flex.

Change em out.


Good luck.

D3 is great,

With D4, the car is not smooth while the gear is changing, especially gear down at the speed 36-39 miles/hrs

Except the tranny mount, anything wrong with my tranny?
