A couple of days ago, I got the A1/222 code (S2 solenoid open circuit) and the check engine light came on, while the car got into the limping mode. After I cleared the code, I drove my car a few miles; the check engine light, the flashing arrow and the A1/222 code came back. Our 1995 850 turbo sedan has 200+k miles, and it has been in my hands for the last ~18 years (i.e., since I bought it new).

After I went through a fair number of related web-info, I went to a neighborhood transmission shop, and he quoted me $400-500 for the solenoid #2 replacement in my car. However, he indicated that there may be other parts that are bad in the transmission, while the same code pops up, i.e., 'S2 solenoid open circuit'. Does that make sense?

Also, it was stated to me that a used replacement transmission will have to be from another 1995 Volvo that may actually have more miles on it. That is, different year volvos have different transmissions. Do you have any feedback on this?

A good job of cleaning and fixing the existing transmission was quoted to be in the $2k+, while a transmission replacement would be more expensive than that. In both these cases, I indicated that I would be inclined to sell or donate my car rather than have it fixed.

I guess part of my question is whether I should go ahead with the $400-500 gamble in just having the S2 solenoid replaced, assuming that there is nothing else wrong with the transmission (please remember that the only code I get is 'S2 solenoid open circuit'). Everything else in the car seems to work perfectly well at this time. I am open to any comments/feedback you may have.

Thank you.

The 222 = open circuit for the S2. This is usually caused by dirt or chafed wiring. In either case, replacement is probably needed. The transmission is not dropped to replace the solenoid, but getting to it is a real pain.

You just flushed your ATF, which did not cause the problem. The build up of sludge was there all of the time.

The mechanic was just covering the bases, will he find other problems? Tell him to replace just the S2 and clean up the surrounding area. Look for a 2nd opinion at another reputable shop (not Ammco or other chain). I suspect a 2 hour bill would be reasonable.

Getting a tranny 'rebuild' is costly, to say the least. Your car can use the 4 speed from any 94-98 850/70. Actually, the 97 850 tranny is a great fit. Replacing the tranny is not a small job, and expect at least $800-900 in labor, plus the tranny cost.

If I lived close by, I would buy it to give me something to do. Donating is a problem these days, you get a receipt for the actual auction price and the Feds let you deduct 1/2 of that for taxes.

Thank you very much for your suggestions and comments.

Upon recommendation of a good friend of mine, I took my 850 to a specific transmission shop/garage in Chicago. After I was talked into having a thorough check up of my volvo's transmission, I reluctantly agreed for $150 (that I paid up front). Well, earlier this week, I got the report: solenoid #2 is fine; one electrical connection between the TCM and the solenoid was corroded and they cleaned it/replaced it. Therefore with a grand total of $150 (the amount I paid for the transmission check up) my car is running beautifully again (at least for the time being). I hope it stays that way! I am wondering whether anybody else had a similar experience over the years.

Nice catch! Worth the money, too. Most shops will not follow wiring.

The solenoid would be the primary suspect I would guess. Your mechanic would probably pay around $50 for the part. If you bought it you'd pay around $125. Charging you $450 to install it seems a little on the high side. I've read that it's not that hard a job. Just remove an access plate on the top of the tranny and all three solenoids are right there. Maybe get another estimate?
