Earlier on today my car a bmw 318ci 2005 got stuck in heavy snow. After having been towed out and having to use a lot of revs ,slipping the clutch etc the engine emission values warning light is now on. Query cause?

How many miles have you done? Is the trans correctly filled with oil? Why do you think its slipping, when it changes up is there some delay in forward pull from the engine that gives similar symptoms to clutch slip? Its not that old and a well maintained trans that hasn't done much towing should do 150k without problems. Towing heavy trailers kills auto trans.

If you tow your car in neutral how come is stuck on one gear. Towing got no problems. That mean it wasnt in neutral it was in gear but the clutch is stuck and seem the gear is in neutral. You should have clutch problem before you think about gear box.

That is a statment not a question

You obviously know that the car has to
come apart & be repaired at the cost
of about $900.00 min for new parts

try here mate it could help.ask around their forum https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=4&cad=rja&uact=8&ved=0ahUKEwiSg9vlk4fXAhXLXRoKHU7GBLYQFgg-MAM&url=http%3A%2F%2Fwww.bimmerfest.com%2Fforums%2Fshowthread.php%3Ft%3D680588&usg=AOvVaw2mf1VDdyWEzytl6ZU9LdSc

Hi nkihima,

If you have both a warning light and the transmission is slipping, I would recommend having it towed to a shop. The transmission in your car is prone to leaking transmission fluid from the mechantronics sleeve, and or the transmission pan. You may or may not notice if you have a fluid leak. Covers under the car catch a lot of oil leaks. If transmission repairs are performed, I would recommend resetting the adaptation values as well.

Excessive wear on clutches is usually from alot of heavy hauling, pulling heavy trailers. 40,000 miles is real excessive. If you can, I would take the access cover off the bottom of the bell housing and check to see if the pressure plate bolts aren't backing out. When the clutch was replaced they should have (or I would have ) used a thread lock on these bolts. There is always a lot of vibration in this area, and I have seen these bolts back out, on manual and automatic transmissions.

sorry to say this trans has to be removed and rebuilt seems like od clutches burnt out-do you tow heavy trailer with truck as you have to tow with od off(push button on shifter)

go on ebay and purchase a repair manual disk it will have an electrical locator schematic on it

Check the transmission release bearing and the gearing of the transmission check if you need to replace the release bearing.

This actually happened to me in my '91 taurus SHO. As they towed it off, the driver looked under the car, and noticed the gearshift linkage had slipped off. He reconnected it right there (no tools required other than we had the front of the car lifted off of the ground) and I drove home.
