This is on a 95 bmw 525i automatic. Car has about 211,000 miles. Now has about 3,000 miles on rebuilt transmission.
Following is a description of the problem
Problem usually happens on first start of day. However it has happened at end of the work-day about 9-10 hours after first start. Problem seems more pronounced if car sits for a couple of days. Also, problem happens randomly but seems to occur more often on a colder day when temperature is below 40 degrees especially when near freezing.
Follows is a typical cold start. Start car, put in reverse and use “moderate” throttle.( problem is less if you let car move with no or very light throttle), car starts moving and engine revs as if in neutral, then gear engages. I have not changed throttle position. This can happen 1 to 3 times (If I reduce throttle, gear engages). Car can die at that point or may operate normally. Puzzling.
Left it with my indy over the weekend. He even drove it home and tried it two cool mornings. Lowest temp was about 22 degrees. As I have said before, my going out of gear in reverse is random and did not happen for him. We relaced the shift cable and rechecked fluid levels. He is most concerned and he is going to contact the rebuilder Precision European Transmission in Ca. They may start with replacing the valve body. Thoughts?
