Steptronic transmission problems
Hi all. Got my 2001318i up to 295000kms and still running ok generally speaking. However for the last 50k we have been having a weird problem with the tranny. When going up an incline at about 60-70ks an hour the transmission seems to slip from 3rd to 4th. You can hear a whistle like noise and then it goes in to limp mode. Switch it off for a few seconds and it is fine. Drive it in manual and it is also fine as long as you keep it in 3rd until you hit around 80kms. Any one else have any knowledge of this problem. All suggestions greatly appreciated.
