97 Camry Shakes When Accelerating

My 97 Camry shakes when accelerating.

First thing i did was check the trans fluid (automatic). The drip stick showed itself to be very well high above the max fill line for running hot. So i drained the pan, and replaced the fluid with 2.6 QTs as recommended by Haynes auto manual. The dip stick still shows itself to be high and at the same spot as previously. The problem still persist.

I recently have changed the front rotors and brakes how ever i do not feel that would be the cause to the below symptoms.

-Shakes on and off when accelerating while O/D is on.
-When O/D is off occasionally shakes.
-Rarely shakes when manually shifting.
-Shakes often when driving up hills.
-With O/D on, acceleration beyond 60 km is near impossible as it constantly shakes.

Any advice would be helpful, thank you.

is engine running rough? if its missing that could cause your shake. put it in neutral while your parked and rev it up a ways and see if you get a vibration that way. to get your transmission back to right level you can pull one of your transmission cooler line and start and run engine with line in a bucket to get some of the fluid out. then with car running in park slowly add it till its on the full mark. some cars have a full cold and full hot line as trasmission fluid does expand when hot
