Default Not shifting out of 1st Gear

On occasion, after coming to a stop, my 2000 S40 will not shift out of first gear. I can go about 25 MPH with the RPMs at 4500. Sometimes it downshifts prior to coming to a stop and then upon hitting the gas it will not up-shift. I have had it checked (nothing found), flushed the transmission fluid and done all software updates and it still acts up intermittently.

This has never occurred while cruise control is engaged and has never tripped the “check engine” light or “transmission failure” arrow on the dash. Typically after driving with it in 1st for 1-2 minutes it will adjust and shift fine for the rest of the day. It’s really strange as sometimes it will run fine for weeks and then it will act up every day for a week. Seems to occur after about 20 minutes of driving or is triggered by a quick stop (say at the gas station) followed by continued driving.

Tech… others… any ideas? Could it be a bad PNP switch or Transmission Control Module or worse… transmission going out? It just seems strange that no error codes are being tripped. Thank you.

You said no codes at all?
What condition is the fluid in?

Thanks Tech, I really appreciate your response. No... that's the weird part, no codes at all and nothing stored. The Volvo repair shop was perplexed too. The fluid looks fine, but I thinkI'll change it again anyway. Does it sound like a PNP switch or a speed sensor? I know those trip codes, but I just don't know what else to do.

Thanks again,
Justin

I would say maybe a soleniod is sticking and then finally lets go to allow the tranny to shift.

Thanks Tech. I think that there are two shift solenoids on the tranny... how difficult is it to change them? Looks like you remove the valve housing cover.

I believe it isn't all that bad to do. It is pretty much the same tranny as the 850 but in the S40 it is alot easier to get to .
Look for the black cover on the front of the tranny they are in there.
