advantex 0 Report post Posted September 8, 2008 Need someone to enlighten me on auto for the 535iA M-Sport [1989 E34]. It is a four speed (I assume - 1.2.3.D etc) yet there are 5 changes so I take that it has like an overdrive as well? Sorry, dont know what model auto it is.

BreakMyWindow 1874 Report post Posted September 8, 2008 most probably the torque convertor going in to lock up mode - do you feel the "fifth change" at motorway speeds? Quote Share this post Link to post Share on other sites
advantex 0 Report post Posted September 8, 2008 Not sure thats why I posted this [All in E mode] - Around town, no different. Slow accel 50-70k feel change at about 65/70k. Slow accel 70-100k another change at about 100k (that makes 5). 100-90k decelerate, can feel change and engine braking if continuing to decelerate [slow accelerate up from this causes change back again at about 100k] Fast accel 70-120k no change, ease back acceleration and two changes follow.
