Transmission is shaking soon after car is started. It slmost stops after about ten minuets.

you need to check your fluids there. You could have run it with out transmission oil and cooked your clitch pack in your transmission. Good luck. You should check all your flids, that means oil too.

possible broken motor or transmission mount

Year make and model ??

Replace the air flow meter.

I have this same car with exactly the same problem. Begins shaking at 40mph and stops shaking as soon as you let off the gas, but then begins again as soon as you press on the gas and smooths out as you get over 50. And the shaking is not felt through the steering wheel. Solution: Replace the transmission mounts. There are two of them, one on each side mounted on the frame right next to the shock strut. There is also a front and rear engine mount, but I replaced the two as described and shaking is gone.

Seems to me the transmission is locking up. Have the tranny oil replaced by a reputable workshop or good friend :-) just remember to replace the filter, located inside the tranny. For this the tranny sump plate need to be removed, and the work area must be very clean.

Holy **** you need a new transmission or check the fluid in it. Cus that shaking means the trans is locking up and doesnt want to move get that checked out soon. Or the mounts could be gone also. But either way thats not safe. Hope that helps
