I have the same kind of deal going on! If I'm going over 45 to 50 mph and am accelerating (without "kicking down") it shakes like a mother. I changed the trans fluid, both diff fluids and U-joints and still shaking. If I go over 65 it just shakes constantly if I'm not perfectly level or going downhill. If I press on the brakes (under 65) the torque converter "unlocks" and the shaking goes away, but if I'm over 65 it doesn't do anything. What the F&#% is going on?

 

I can't remember what the code was, but just inside the pan is a selnoid pack and that is it.

Well, I took it to the tranny shop last week and they told me it was the transmission, so after a tranny, different selnoid, different torque converter, they informed me today that all this didn't fix the problem and is still doing what it was doing. SOOOOOOOOOO basically I just blew $1200.00. They are now saying it could be the computer, What the heck. I am at a lost and don't know what to do now. Does anyone have any thoughts????????

 

small claims court...they told you a repair would solve the problem and you spent money....it didn't fix the problem...

If you can show that they failed to use the standard of care that a normal shop would use to determine the problem then they are liable for negligence....

don't ask..I also went to law school after quitting my job as a tranny mechanic..
