BillofRights Posted October 18, 2013 Share Posted October 18, 2013 I have a 2005 Legacy Outback, 3.0 L Boxer 6. The cruise control won't operate becasue the CEL comes on and shuts it off. Dealer tells me code is P1844, which means a valve body in the transmission, and their estimate to replace it is $1400. My question is, is this a repair I should only trust to the dealer, or can any worthy repair shop handle it? Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted October 19, 2013 Share Posted October 19, 2013 I would only trust a shop that specializes in Subaru repair. It would be a good idea to find an independent Subaru shop and get a second opinion. Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted October 19, 2013 Share Posted October 19, 2013 Unless the tranny has had meticulous care and/or recent fresh fluid put in, I'd be tempted to try 3 drain/fill/drive/repeat cycles - and maybe some Lucas or CRC trans-max type additives before spending $$$$$. maybe the valve is just gummed-up 1 Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted October 19, 2013 Share Posted October 19, 2013 With an estimate of $1400, is that to replace the tranny? I would bolt in a used tranny for a lot less money. I like Texan's advise about doing 3 drains and refills of ATF with an additive to see if that fixes the problem. However thinking about this................................I always thought that the cruise control system is vacuum operated, and not interactive with the transmission, but maybe that is not true with newer cars. However, if still simply vacuum operated, then I don't see how working on the tranny can fix the cruise control problem. If that is the case, then the CEL for the tranny is a separate problem.

Fairtax4me Posted October 19, 2013 Share Posted October 19, 2013 Newer cars deactivate the cruise control when the CEL is on. Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted October 20, 2013 Share Posted October 20, 2013 another way to proceed would be to post a new thread asking for a shop suggestion near Worthington. maybe someone knows of a soob experienced independent mechanic that could offer a second opinion.

coclimber Posted December 5, 2013 Share Posted December 5, 2013 Newer cars deactivate the cruise control when the CEL is on. Any idea what year they started deactivating cruise on a CEL? Quote Link to comment Share on other sites More sharing options...
luko Posted December 6, 2013 Share Posted December 6, 2013 (edited) If you're going to use an additive use Lubegard, best stuff out there Edited December 6, 2013 by luko Quote Link to comment Share on other sites More sharing options...
fishy Posted December 6, 2013 Share Posted December 6, 2013 Any idea what year they started deactivating cruise on a CEL? I'd guess that started with the new generation in 05. My 05 does it but my friend's 03 doesn't. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted December 6, 2013 Share Posted December 6, 2013 Any idea what year they started deactivating cruise on a CEL? Not sure exactly. I would have to guess most manufacturers started doing that around 2000. Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted December 6, 2013 Share Posted December 6, 2013 It depends on what the CEL is on for. If it's kicking the cruise off, it's because the computer thinks the issue is bad enough to not be able to set it. Looks like you can try a drain and fill on the transmission with a new filter (located in the wheel well in reforming of the driver front tire behind the fog light) but if that doesn't work, probably will need a new valve body or a transmission.

1 Lucky Texan Posted December 7, 2013 Share Posted December 7, 2013 on some cars, cruise and traction control , maybe other stuff, will deactivate. it does seem like around 05 is when this kinda started. Quote Link to comment Share on other sites More sharing options...
