Hello,
I have an '89 240 series sedan with the 5 spd M47 transmission. Its the eurpoean model, not US. The transmission will not shift into reverse. The ring seemd to lift fine. The prev owner told me that there is a micro switch somewhere on the sifter that is not working. My Haynes manual does not show any type of a switch. Has anyone ever had or heard of this problem? Thanks in advance!

Are you saying that the lever won't move over to the left into the reverse gear plane? If so the guide bolted to the top of the shifter support cage (up under the shifter boot) is likely loose or somehow out of position. When you lift the detent collar, it lifts a block, that is built into the shifter, up and above the guide so that the lever can move over to the left. There is no electrical component, micro switch or otherwise, that would prevent the shifter from moving into position.
If the lever is moving over to the reverse gear plane but when you push forward it won't go in, try putting the shifter into 4th gear, then directly into reverse.
Otherwise it might be failed shift linkage bushing where the shifter can't quite twist the shift rod enough. Or the clutch might be dragging; try putting it in a forward gear on a level road and if the car creeps forward, it is dragging.
