Missing the 1st to 2nd shift...RID shows 2nd gear ?

Yesterday while tooling around, I happened to miss the 1st to 2nd shift - or so I thought....

 

When I shifted, it felt normal, until I released the clutch and rolled the throttle and the RPMs shot up. I looked at the RID and it showed 2nd gear. I kicked the shifter up again, and it went to 3rd.

 

I'm curious as to what happened - anyone have an idea?

I've missed shifts before, mainly 1st - 2nd and the RID is always quick to show "O". I don't ever recall it being off by one count though.

 

I used to have/find false neutrals all the time on my harleys but haven't experienced that on my BMW yet.

 

Sorry I can't help ya with this problem.

If it's a one time thing, probably not a problem. I've missed many shifts in my time. The indicator usually indicates "O" or is blank. Haven't seen a "2". The shift drum might have moved enough to put the gear indicator switch into 2 without actually shifting far enough to engage 2nd. If it continues to happen it would indicate the start of a problem. Probably worn shift drum/fork.

That is sort of what I was thinking, but wasn't sure of the terminology (shift drum).

 

I only have 10K on it, so I hope it is not a wear thing. I miss the shift from time to time, but this is the 1st time I noticed it said "2" instead of "0" on the missed shift.

 

Thanks for the replies

I have the same thing happen to me all the time. Same scenario, "tooling around". If you just our cruising your make very soft movements and inputs. The shift from 1st - 2nd is larger then 2nd - 6th. You need to be aware to fully bring your foot up the full stroke length of the shifter. Others have said, "Pre-load the shifter, just before disengaging the clutch." Both practices will work. I just never liked the feeling of the pre-load.

If the problem seems like the tranny is actually shifting OK, but the RID is wrong, the most likely culprit is the gear position switch on the rear of the tranny.

+1 on the potentiometer being the culprit

PIA to get to.
