AT shudder before gear change

Hi,

What are the signs of a bad transmission mount?

My symptom: Especially when warm, I notice a shudder or shake just before the trans gets to the point where it will change gears. Once the change begins to occur, all is fine and the actual gear change is fine, clean, quick and smooth. Its just that fraction of a second leading up to the gear change, when there is almost always a noticable shudder. It seems to be more noticable in the 1-2 and 2-3 changes.

Transmission actually performs shifts fine, 100%, although sometimes does an immediate 2-3-4 shift. Fluid stays nice and clean red, changed regularly, allmost entirely highway driving.

Fluid used is quaker state, as they claim to have MB acceptance as a correct Dexron fluid for MB auto transmissions. It has maybe 20k, probably a bit less on it at the current time. Filled to the correct level, nice bright red.

Any ideas?

I just got a case of castrol dexron III as it has been certified and licensed by GM (originators of the Dexron standard) as a dexron III fluid with 100% compatibility as dexron IIE, II and standard dexron fluid for all cars made 1983 or later. The first line on the back of the bottle says its specially formulated to meet the new GM Anti-shudder specifications of Dexron III - Thus my temptation to try it.

But would you think this to be a fluid issue or a mechanical/mounting issue. Hopefully its just a trans mount, but I sure dont knwo how to tell.

Any help would be great.

Thanks,

JMH
