The deal is that I assume there is some warranty on their work and if it is still not right, then insist they tear it down again and fix it right, lest you sue them based on the warranty.
The fact that it shifted smoothly for a day after they replaced the motor mounts though sounds fishy. Harsh engagement to reverse or drive can be due to different things including motor mounts. You may want to have a look at the test procedures manual for your trans to see what it says about that. I recall that to reduce that harshness, the trans actually shifts to some intermediate gear before shifting into drive. As well, a high line pressure due to a faulty or misadjusted regulator in the valve body or a problem with the throttle pressure cable can be a cause. Ask them for the line pressure test results for the stall and shifting tests. Is there any harshness in the shifts from 1-2, 2-3?
Also, faulty solenoids does NOT warrant a complete trans teardown. They are all accessible when the pan and valve body are dropped. Did they replace the valve body too? If so, they may have missed a seal or the new valve body could be faulty.
