Way my bmw 2006 525xi is shicking when i drive slow only when the cargets worm

i think this is a rear drive car so the boot might be going inspect the rear boot for grease leaks near the tire

Definitely a trans problem

Seeing as how you have continued to
drive it, even 5 miles,when it wasn't working
correctly, as well as ignoring the fault code
light,I doubt that there will be a fix

Your most likely going to spend north of $3,000
for a reman trans

The air filter housing would have to be almost off
& you would have checked that before asking

If it were loose, it may upset the shift stratagy,as the
MAF Sensor may be part of that

But the slowing down,& slamming into different gears,
just one day of driving like that, you ruin the trans

sounds like the tps sensor ...is there any warning lights on?

Have the transmission checked.

WELL I WOULD MAKE SHERE YOU HAVE NO AIR POCKET AND CHECK WATER PUMP AND COOLING FAN IS IT PUSHING COOLANT OUT WHEN CAR IS WORMING UP MAY HAVE PLOWEN HEAD GASKET ONE WAY TO CHECK FOR HEAD GASKET IS GET CAR WORM AND LET IT SIT AND PULL PLUGS NEXT MORNING AND HAVE SOME ONE TURN MOTOR OVER AND SEE IF YOU SEE MIST COME OUT OF HOLES WITCH MAY BE COOLANT

what type of bmw and the year

This is a classic fuel distribution distributor issue, clean the throttle plate, you may also have to adjust the fuel trim.

you could have a faulty sensor or a loose connection to said sensor. your trans control module needs to be checked by a diagnostic scan tool at a shop there they can check the module and see if there is a fault in you drive train. i doubt it's an internal problem with the trans....please rate this....thanks
