Need Help! '01 C320 Transmission Fluid

I bought this car 97K and now it's 141K miles. I have never changed the transmission fluid because I forgot to do it. However, it runs great tho. This week, I bought 6qts Valvoline MaxLife which on the bottle it says compatible with Mercedes. I took them to my mechanic tell him to replace the old fluid. I have an automatic transmission. He put 5.5 qts. I drove out the shop for 5 minutes and at the red light, I was on "D" when release the brake, it just not move forward. I had to try push it for 5-10 seconds. It happened a few times. The power seems low and gear stay 1, sometimes move to 2 very smooth, sometimes not. I drove back to the mechanic immediately. He said the Valvoline MaxLife is not good for my car. He inspected the transmission (Took it apart) and told me to trade-in get a new car but it will cost alot to replace or replace the transmission!!! He said we should have used the Mercedes Specific Fluid. I am so sad now. I cannot decide what to do. My questions are:
1. Should I believe him? I mean it runs great even with the old fluid / even before the fluid change.
2. If it's true, I just cannot beleive that driving for 5 minutes can screw the transmission this bad? Is it too late to put the Mercedes Specific Fluid in....and try again? Will my car be back to normal?
3. Thank you for your help!

Take your car to a Benz dealer, or an indy mechanic that specializes in Mercedes, and have the tranny properly serviced. The tranny fluid level is critical, and it sounds as if your mechanic did not properly fill to the specified level.

+1 to Andrzejek. People have used MaxLife and had no problems with it. But in your case I would first check the level, and then try the real deal 236.10 MB ATF.
