stevec Posted May 7, 2004 Report Share Posted May 7, 2004 I need help. The arrow is flashing and I think my 93 850 is in the limp home mode. It starts out like it's in high gear. I believe the S1 solenoid is bad according to the fault code. It says the is an open circuit for that solenoid. Is the solenoid under the transmission oil pan?

jda2000 Posted May 7, 2004 Report Share Posted May 7, 2004 I thought the flashing arrow meant a failing PNP switch. Does the car start fine in P or N? Link to comment Share on other sites More sharing options...
stevec Posted May 8, 2004 Author Report Share Posted May 8, 2004 Yeah the car starts fine in both park and neutral. It seems the car begins in first gear but then flips to the highest gear when it should be going to second gear. Even when manually shifting it does the same thing.

Bay13 Posted May 8, 2004 Report Share Posted May 8, 2004 The flashing arrow means reduced transmission ability, or code stored in the TCM. There are 3 different levels of reduced abiltiy(limp home mode)The solenoids are under the valve body cover. If you look at the transmission lines that go to the radiator the line connected to the bottom of the radiator connects to the top of the valve body cover.

stevec Posted May 8, 2004 Author Report Share Posted May 8, 2004 I'm getting fault codes 114-program selector open circuit or short to supply. Code 122-Solenoid S1 open circuit. Code 211-transmission control module fault. Thanks,Stevec Link to comment Share on other sites More sharing options...
stevec Posted May 8, 2004 Author Report Share Posted May 8, 2004 Oops! I forgot to mention the car will not kick down into passing gear either. I'm not sure if that last tidbit of info helps someone figure out what is wrong. I did do the cycling of the shifter 15 to 20 times to clean off the contacts on the PNP but it didn't help. Maybe I should just pull the PNP and check it out or replace it. Someone else on this forum said AutoZone has it for $38.00 and they call it a neutral safety switch.

Bay13 Posted May 9, 2004 Report Share Posted May 9, 2004 the 114 for the selector mode is common, just clear the code and be on your way. Don't worry about replacing the W,S,E switch unless you have coke or stuff in the switch.the S1 solenoid is more than likely your problem, with the no kick down and such. Don't believe the PNP has anything to do with your trans problem. Link to comment Share on other sites More sharing options...
stevec Posted May 9, 2004 Author Report Share Posted May 9, 2004 Thanks Rich,I'll check out the solenoid and let you know how I made out. Stevec Link to comment Share on other sites More sharing options...
stevec Posted May 10, 2004 Author Report Share Posted May 10, 2004 Rich,I hope you can help me find an S1 solenoid. I went to the dealer in town today and they told me they not only don't have them in stock. They can't even order one for me because they don't ever service an automatic if there's something wrong inside. They simply replace it with a rebuild. Sounds like it's a good way for the dealer to get some extra cash from the customer huh. Okay I'm done slamming them now. Could you direct me to a source where I can buy these solenoids? Thanks for your help in the past.Steve Link to comment Share on other sites More sharing options...
Bay13 Posted May 11, 2004 Report Share Posted May 11, 2004 Slam noted and deserved in this case. There is a part number for the solenoids and they can be ordered. With that said, lots of times the solenoids will be replaced and things will be fine for a while and then they begin to fail. Could be the crud in the trans is causing the seals on them to leak or not work correctly, so often the trans rebuild/replace is done instead of replacing the soleniods.Three solenoids in the valve body. S1 and S2 are part number 6843783 and the SL solenoid is part number 6843784. Link to comment Share on other sites More sharing options...
stevec Posted May 11, 2004 Author Report Share Posted May 11, 2004 Thanks very much Rich I'll be seeing them tomorrow.Steve Link to comment Share on other sites More sharing options...
Chris_R Posted May 11, 2004 Report Share Posted May 11, 2004 Maybe I should just pull the PNP and check it out or replace it. Someone else on this forum said AutoZone has it for $38.00 and they call it a neutral safety switch. StevecThe neutral safety switch that Advance/AutoZone offers is something else. You can order a PNP online for like 128 I think. I paid the extra 5 bucks and got it at my local independant Volvo repair shop so I could get it the same day. You'll probably have to drop the tranny (or at the VERY LEAST the subframe) to get at the valve body. I swear I think Volvo built the car around the tranny!-Chris Link to comment Share on other sites More sharing options...
stevec Posted May 14, 2004 Author Report Share Posted May 14, 2004 Rich,I went to my local volvo dealer yesterday to order the S1 solenoid for the part number you gave me (6843783). A mechanic who was working in the parts dept said no problem that he could get it for me for $98.00. A service manager overheard our conversation and said, to him it sounded like the problem was the PNP. That put just enough doubt in my mind that I bought and installed the PNP since it was at the very least an easier task to replace than the solenoid. Well the PNP apparently was not bad since I still have the flashing arrow. So I went back to the dealer this morning to order the part. A different guy was looking up the part number and he came back to say that this solenoid isn't for my transmission. He also said he's never heard of these things failing. So now I'm back to bugging you. Obviously I don't want to buy this solenoid if it is the wrong part because as you probably know I can't return it. So my question is this. Are you sure this solenoid will work on my AW50-42? Also logic tells me that as long as I'm in the valve body I should replace both solenoids. Now it's only fair to tell you this parts guy didn't have much confidence in my getting info over the net as he said about 80% of information there is wrong. Personally from the advice I've seen so far with you helping others, I feel you know what you're talking about. Let me know as soon as you can what you think about this.Thanks,Steve Link to comment Share on other sites More sharing options...
stevec Posted May 15, 2004 Author Report Share Posted May 15, 2004 Rich, Can you check out the last entry I put in? I had to clear up a question. Thanks,Stevec Link to comment Share on other sites More sharing options...
Bay13 Posted May 16, 2004 Report Share Posted May 16, 2004 I'm about as sure as I can be concerning the part numbers. I looked up a 1993 850, with a AW50-42 transmission. I'm using VADIS version 6.5.2654, 2004 "B". (the latest version off the press, only about 3 weeks old) The S1 and S2 Solenoid are listed as part number 6843783 and the SL is listed as 6843784.A service managerService Managers are not paided to diagnosis cars.Also logic tells me that as long as I'm in the valve body I should replace both solenoids.I'd replace all three, S1, S2, SL.this parts guy didn't have much confidence in my getting info over the net as he said about 80% of information there is wrong.Tell him you got the part numbers off VADIS with 2004 "B" installed. If they haven't up dated lately it's on 2004 "A" and the one before that as well. I do know what he means about net info though.With all this said, remember what I said about solenoids, sometimes it works sometimes it doesn't. When you get ready to do it PM me or give me your phone number and I'll give you a few pointers to get the Valve body cover off and on. Link to comment Share on other sites More sharing options...
