The first thing i would do is check history which would mean talking to the gentleman you bought from. Find out if his brother ever had issues like this. If not, then the other thing to look into is what fluid did the servicing shop use. These transmissions use mercon 5 semi synthetic. The older fluids don't mix with the new ones. Fluid level is also a factor as was previously stated. Did the servicing shop drop the pan and change the filter? If so,they could have bungled a connector for the tcc solenoid,or loosened the connector to the outside of the trans too.The latter is not likely as you would have other issues within the trans as well. Although flushing the trans fluid is good,i always dropped and cleaned the pan and changed the filter. A good trans shop should have a service tool to test the solenoids. They basically put power to them and listen for an audible click. If i remember correctly,the solenoids are a pack and not individual. Might be an expensive venture to repair,parts can be pricey. If it's just the solenoid pack,at least the trans wouldn't have to be removed. Worse case would be the torque converter lock up itself which would mean pulling the trans to replace the torque. I would lean towards a wiring or fluid issue if it just started. Should be a relatively easy fix. And yes,i am an ex transmission man,hence the name. Hope this helps,good luck. Keep us posted. Robin.
