Good Evening Friends!

I have good news. After your suggestions I purchased an iCarsoft MBll scanner specific for Mercedes. I received it today, registered the scanner online and downloaded the updated software. I hooked it up to my car, ran the diagnostics and cleared the codes. Took it for a test drive and hallelujah it shifted like it was new. I am very grateful for your help, otherwise, I'd would have probably taken it to the dealership and paid much more than what the scanner cost. This is a great forum.

Hopefully, this specific post will benefit others.

Thanks again friends!!
