Hi Subi Fans, 

I have a 2005 Outback, 3.0R VDC 5AT w sport shift.  Recently the CEL came on and produced code P0768, which has to do with the Shift Solenoid 'D' electrical. The solenoid is located on the control valve assembly, which is inside the transmission pan. The problem is intermittent, and I have been able to reset the code several times, but within a few miles the CEL comes on again. This last time while pulling a steady hill as it went to shift between 3 and 4. Until my next reset, it is stuck now in one of those gears. The sport shift would not work either. Of course, about half the lights on the dashboard are going wild, and cruise control is dead.

After much investigation I am pretty sure no one is re-manufacturing or rebuilding these valve bodies, and no solenoids can be purchased separately. 1) Does anybody know where I can get a rebuilt valve body with tested solenoids?

I have found a used transmission (131,000 miles) for $485, which includes shipping. 2) Is it a good idea to purchase a used transmission and then remove and reuse the valve body from it?

Subaru still sells the valve body under part #31705AA4309L, and those run $750 to $935. It is a new part and has at least some warranty. This valve body fits a good number of 6 cylinder 5AT Subi models from 2005 to 2007. 3) Is my best bet going to be a new valve body?

Last question. It is kind of a messy PITA job to get inside the tranny case just to look at the wiring and make sure things are plugged in, and replacing all the tranny fluid is not cheap. If I am opening it up I want to replace the valve body (or the D solenoid). 4) After replacement, does the car's computer need to be reset? Or can I just drive away? 5) If so, is that something I can do, or must the dealer (or my good independent garage) do it?

If anyone can help, or has any resources, please let me know - I am OPEN TO IDEAS. The car is great otherwise, but has a salvage title and 208K, so we are getting leery of big expenditures to keep it going. I have had it for eight years.

THANKS !!! Craig

Disclaimer:  I know nothing about ATs; the extent of my experience is replacing the 4EAT in my '99 Forester.  It was suffering from a neck-snapping 4-3 downshift under power - if you stepped on it for passing, to get power on a hill, etc., it felt like you were being rear-ended at speed.  No codes.  Xmission repair shop estimated $2400 (a nonstarter).  Found a matching transmission in a junkyard car; it had body damage (implying it was mechanically sound when taken off the road), so I took a flyer and spent $130 and an afternoon dropping it.  When I bolted it up it worked perfectly.

Having said that, if I were in your situation I'd get my butt to a (preferably self-serve) wrecking yard and pull a valve body.  Around here they charge $50 for them.

J909, thanks for the idea. I have been in contact with several salvage yards, and they are more than willing to sell me a whole tranny. To remove the valve body is basically to remove the heart of the thing, and completely devalues the remaining transaxle - so that has been a non starter. As I mentioned, I am considering buying a used tranny and then removing the control valves for my car. 

Today I spoke with my regular independent garage, the one I use for high level work, and he thought I should buy a new one from Subaru. So, unless someone can suggest a Remanufactured part, that is what I will most likely do. 

I am still not sure about the need to reprogram the computer. Any thoughts, anyone ?  Thanks.

I specified a self-serve yard because they're a completely different animal than a full-service yard.  They're utterly indifferent to the removal of the valve body devaluing the remainder of the tranny.  As far as they're concerned, any money they make on any portion of a car is gravy in advance of the rest going to the crusher for metal weight value.  I didn't pull that $50 (CDN) figure out of my butt; that's what they actually charge around here:

I'm not going to argue the point further - it's your money, spend it as you wish.  I just want you to understand that I'm not blowing smoke here.

On the reprogramming part, I don't know, but my guess is that it wouldn't be necessary.

Thanks again, I asked for advice and I value your response. Certainly not meaning to be argumentative. I used a pick-n-pull yard for a cruise control module for my van, and that worked out just fine.

To be honest, it has been very rainy here, and I don’t look forward to being under a car in a field draining transmission fluid (probably onto myself). In the garage it is not that big a deal. I will make a call or two tomorrow and see if my local yard has one. It is a good idea and a money saver.
