93 740il no reverse
When cold weather hit. the trans started to either hard shift or delayed shift from park to reverse or neutral to reverse. then after a week of this, it would not go into reverse at all. Forward works fine thru all gears. I tried 1 test drive to see if it would work once warmed up. no change. I haven't tried anything else since. I have been searching sites for 740s with similar problems, and I have heard that it might be a plastic check valve inside the tranny. Does anyone know which valve it is? where to get the part? and is this something that can be replaced with out major Z5 540 transmission knowledge
I haven't put it on the rack yet so checking fluid level, shifter linkage. fluid and filter service and the checking the A/M switch have not been ruled out yet.
I'm in rural Montana with limited BMW mechanic access. so I am learning everthing I can before I start to do this repair myself.
