Hi,

I have just bought a 2012 Captiva 4WD. Bought cheap as it had a limp mode problem so took a risk even after reading the horror stories re gear box. Gearbox is fine which is a start also replaced ATF also thanks to this forum. The fault code was PO717 - Speed sensor. Has anyone bought one as I am struggling to find one. Its a 1TOR 6T50 gearbox in 2.2 diesel automatic. I am based in England. Car has 81,000 miles, hope i have put enough details on as I know some people get wrong lol

John You are correct that code P0717 is the turbine speed sensor.

P0717 code definition
The PCM (powertrain control module) will set the P0717 code when it detects no signal from the input/turbine speed sensor. This signal may be interrupted briefly, or it may be erratic or otherwise outside of expected manufacturer settings. The sensor is positioned near the rear of the torque converter (at the transmission input shaft) and is either mounted with a bolt/stud or threaded directly into the transmission case.

The internet probably has it listed somewhere. I found this link under description requested For Captiva but then the page when opened doesnt confirm the vehicle(s) it suits. Turbine Speed Sensor 2 | eBay

Forum Member Scouse-Mafia listed a supplier for GM parts on this link :- Chevrolet Parts Mail Order.

John, whilst you have given your location and vehicle description within the content of your post, successively this becomes 'lost'. It is helpful to complete your World location in your Sign-Up and place vehicle info preferably in your Signature Footer. This way they will always appear automatically with any future posts you make.
Helpful tips for new Forum Members are on this link:- Helpful Guidance Using the Forum

Hope this helps.

ps: it is worth just checking that it is not simply a vibration damaged wire at the sensor or the inline connector with poor connection.

Hi Ed,

Thanks, much appreciated. I have managed to source a new sensor from www.automaticchoice.com (£75.00) which is coming tomorrow and fingers crossed that will work once we put it back together. We have checked wires/Plugs for any bad connections but all are fine. The car has had one owner and full service history and seems to have had everything its needed since new. (Came with all repair bills) so went for it. If its just the sensor its a great buy!

Thanks for the quick reply. Ill drop a line tomorrow to let you know how it went.

John

John, pleased to note you have changed the ATF. Just a 'heads up' that there have been a number of posts concerning the Transfer box over the past two years.
Might be worth considering oil change on this component as well.

Which begs the question: What kind of oil goes in the transfer box for the auto transmission? I believe it's ATF fluid but not 100% sure. Anybody know?

Forum Member Topman changed his transfer case mentioned in a post back in 2018 but he didnt say what the fluid was (Captiva Diff oil, check yours.) post entry #6
Maybe if he reads this he can advise us. :)

Its 75W - 90 that goes into the transfer box. We are doing that too!

I'm not so sure about that JS, there's no hermetic seal between the transfer box and the auto box so there is commonality of fluid between the two and you definitely don't want 75W - 90 gear oil mixing with your ATF.

Oh i better double check.... we were told this by a gearbox specialist yesterday and discussed the transfer box as i mentioned we were doing this too but you have planted the doubt so i will be checking again. Really good to have this forum to check things like this!

Update: so the problem didn’t solve changing sensor, we took it to a gearbox specialist who has said it is the TCM (£1200)however it will need coding has anyone got this done before as I can’t find anyone who can code it? The gearbox place said it needs to be a dealer which of course I don’t have. Any help appreciated.

As I understand it, the Vauxhall Antara uses the 6T50 gearbox (the Antara is in effect a Captiva in a different body shell). I would have thought that it is worth approaching a Vauxhall dealer. Interestingly this seems to be at the discretion of Vauxhall dealers. Some will deal with Chevrolet (after all it is business for them) and others simply adopt an 'it isnt one of ours' attitude.

So what kind of oil goes in the transfer box when it's mated to an automatic transmission?

Ed - yes the dealers have pretty much told us to get lost. Not interested.

Victor - not a clue I think my car will be heading for the scrap yard

Well after a long slog the car has been on the road for a month. It was a snapped wave plate affecting the r-3-5 gears, one part was stuck in the speed sensor which is why it was throwing up the P0717 fault.

gear box repaired and 2 years warranty £2,700.00.

All in all a good end to the issue and not too expensive as i bought the car very cheap.

Sounds like a satisfactory outcome. It is encouraging that you found a suitable repairer who by the sound of it knew what he was doing.
Can you name them. It may be a godsend for other Forum Members to know.
