The automatic transmission may develop shifting problems and/or the Check Engine Light may illuminate due to internal component failure and/or software issues. It is always best to be sure the transmission control module has the latest software installed when any major transmission repair is performed.Google+

Volvo S60 Transmission Shifting Issues Due to Internal Failure and Software Issues
Volvo S60 Problem
Drive Trains Affected: AWD, FWD, w/o AWD
Average Mileage: 123,431 mi (10,500 mi - 250,000 mi)
Rough shifting (1st to 2nd and 2nd to 3rd). Revs up and doesn't want to engage and then does with a "clunk" and wheel squeal. Software upgraded, but problem continues. One mechanic says he has replaced his transmission 3 times. Sounds like Volvo needs a recall.

Problem first started with hard downshift from 2nd to 1st. Now it jerks hard when accelerating,usually at 20 mph. Its like the car hesitates and then jerks as I am stepping on the gas. It is more prevelant in stop and go traffic.

I have encountered a problem with my 2002 Volvo S60. The transmission seems to be slipping in the gears at lower speeds and then lurches or jerks when it catches. Don't know the solution yet. Need to take it into the shop later today.

Transmission slips out of 1st and 2nd and engine revs up. Loud clunk if you don't get your foot of the accelerator. Intermittent. Maybe worse when engine is hot after 10 minutes or so.

Delayed harsh engagement between drive and reverse, slipping between gears and other erratic behaviour. Suggested fixes range from rebuilt Volvo transmission 4,500 to rebuild with new valve body and transfer case not much cheaper. Still haven't fixed it, since I paid about that for the damn thing. Best looking lemon, I've ever owned!

Runs fine until warmed up--then shifting is erratic--gears slip going around corner and then trying to accelerate. Car bucks after leaving a stop light or sign. Always feels like gears are late. Never thought I would regret buying a Volvo. Recall is needed.
REVS UP BETWEEN GEARS. SEEMS TO BE SLIPPING
Needed new software in first year, now shifting rough until car warms up...

This is the 2nd transmission in the car, and has only 20,000mi since replacement.
Symptoms are very hard 2nd gear to first gear shifts as the car slows through about 3mph, especially when hot, or in stop-and-go driving.
Some 2/3 and 3/4 flared shifts.
Learned the Valve bodies are known for sticking components, including solenoids.
The solution is possibly a new valve body ($2000 or so) or a new transmission (rebuilt units installed by Volvo $4000-6000).
Had transmission software checked, adaptations deleted, fluid flushed and refilled by dealer, and it worked for a couple of days, then back to sticking and hard downshifts.

I've had this problem since the first three years I've owned the car. Dealership claims they can't pinpoint the issue and sometimes can't repeat the problem for them to experience it. Upgraded software didn't fix the problem.
