New member here. My Dad is giving me his 04 mini with 150k miles. It had a used tranny replaced Round 100k miles. But I don't believe he's ever replaced AT fluid. So before I other having tranny rebuilt for $3500, do you think it maybe something simple? It drives fine for first 5 minutes after cold start but will not shift out of gear. Anyone ever heard of this problem and possible fix? Thanks for your help.
