Shift mode selector on V70 causing transmission problems V70-XC70

posted by  someone claiming to be bibendum on  Mon Jan 9 16:33 CST 2006 [RELATED]

This is on a 98 V70 GLT (68K miles):

I had the car in with my indy Volvo shop for a transmission inspection since I've lost track of when the fluid was last changed. I've been getting an occasional bump-bump-bump from the tranny either just before or just after stopping as well as some infrequent hard upshifts. The 3 bumps feel like a delayed triple-gear downshift in preparation for acceleration, but that's my own theory.

Turns out the fluid was a little dark and a quart low, but they were not alarmed. I think I've had one flush about 30-40K miles ago. However, they told me that they pulled a fault code in the shift mode selector on my transmission (the 3 buttons that choose sport, economy, and winter modes).

I was quoted $155 for a new switch, but I hardly use the thing, nor have I noticed it misbehaving. Questions for the forum: anyone ever encounter such a transmission symptom? Anyone see a relationship with the mode selector? Can I bypass the switch or, better yet, ignore it without risking tranny damage?

    Did they do the tranny flush? That's what I would do...also the P&N switch could be a culprit. Don't know about the 3 buttons...does it do it in both the E mode and S mode (stay away from W mode unless just starting off or truly in icy conditions).

      They have not done the flush yet - told me I could wait a bit, so I'll combine it with a few other items soon. I don't know what the P&N switch is. I keep the car in E mode almost all the time, so I haven't noticed the triple bump in the other 2 modes. I've never even noticed a problem with the switch, although I have tried using it recently and it seems to function the way it should.

        I had the same problem on my '98. It was identified at 100K and I just sold it at 118K. Never replaced the selector and it never gave me a problem.
