2005 Acura TL trans problem

I had some clicking in my left front axle and was told it needed to be replaced. I had this done at a local, reputable shop and later that day the axle started to pull out and I lost about 4 quarts of fluid. My car made it home and I brought it back to the shop where they installed a new axle and did a BG flush.
It seemed OK for awhile and then it kept going out of gear and would go into a neutral position and just rev.
Did the installation ruin my transmission. I had it towed.

Thanks,
Danny
