Volvo v70 jerks when slowing down

I have a 2004 Volvo v70 (not turbo) with 150,000 miles. After driving the car 5-10 miles, when I slow down to about 10 mph, the car jerks. Acceleration is fine with no apparent transmission slippage. I avoid the jerking by shifting the auto trans into neutral when slowing. It seems like it might be a mount somewhere. Dealer said that it is the beginning of the end of transmission. Any thoughts out there?

It is very likely that you are feeling a rough downshift to first gear as you slow down to 10 mph. This will tend to happen when the transmission’s fluid level is low, but I have to assume that you have checked the trans fluid and ruled out this simple fix.

But–perhaps even more important is this question:
When was the last time that you had the transmission fluid changed?
If you have not had this done every 30k miles, then it is likely that your transmission is nearing the end of its life. Transmissions that are not serviced on that type of schedule can fail any time after ~100k miles, and failure is pretty much of a sure thing by ~150k miles.

I would suggest that you take the car to an independent transmission shop that has been in business for at least 3 years, in order to get their assessment of the symptoms and the condition of the trans. Whatever you do, DO NOT go to AAMCO, Lee Myles, Cottman, Mr. Transmission, or any other chain operation unless you want to be told that you need a new transmission–whether you really do or not.

My 2005 V70 shifts down at the last minute too, and it also revs before kicking into gear when I’m accelerating. It starts about 10 minutes after driving around town or in stop-and-go traffic, then gets steadily worse until it’s been off for a couple hours. I’ve taken it to 3 independent mechanics and 2 Volvo dealerships - all of whom have done everything imaginable, including flushing the transmission. I’ve also had a bunch of diagnostics done, but the check engine light never comes on so no one can tell me exactly what the problem is except that it seems NOT to be a problem with the transmission. Someone finally suggested that it might be the car’s adaptive learning software. There was an upgrade available, but I was told by one dealership not to bother - that it works only about 50% of the time and the other 50% of the time it makes the problem worse. I stuck it out for another year before I finally got so fed up with it that I had the upgrade done. It was better for about 3 days before it started acting up again. In the end a co-worker had the best advise. If it’s the adaptive learning software, then disconnecting the battery should reset the system. That’s the ONLY thing that has worked! Every few days I have to disconnect the battery again (and reset the clock), but it runs much better for a few days before I eventually have to do it again. It sucks, but it works!
