Today I had the BMW Dealer perform this update. It corrected the problem but created another one. Now I have a hard shift on the 1-2 upshift on medium to heavy acceleration. I am very disappointed to say the least. I welcome any suggestions. Thanks.

On the hard shift from 1-2 what rpm is the engine at? If the engine is at 5000 or more rpm the shift will always be hard. Driving aggressively will cause the engine to shift at a later point on the rpm scale.

upshift 1-2 gives a blow and stop at traffic lights slams.
The car has 58000 km, someone can tell me if it has been fixed.
The first morning shift 1-2 is smooth.
thanks

Why don't you bring it to a specialist before you cause more damage to the trans by ignoring the symptoms and keep driving the truck. At the very least get it scan for fault code. Can't afford to bring it to a specialist, then a used BMW is not the right car for you.
