Hi, Started Forester this morning and noticed powerlight on dash flashing and only have 1st and reverese.

Disconnected/reconnected battery and this did not help. Trans fluid clear red colour. Gearbox has not played up before.

Any thoughts please

I'm no expert at all on auto transmissions, but found this list of possible causes for being unable to shift from 1st to 2nd in the service manual:

 

• TCM
• Rear vehicle speed sensor
• Front vehicle speed sensor
• Throttle position sensor
• Shift solenoid 1
• Control valve
• 2-4 brake

 

If the light's on it should be producing codes, best to get them read then you'll have an accurate idea.


May the Foz be with you....

Reading fault codes yourself isn't difficult and can save a lot of cash: on newer cars you just need an OBD cable and appropriate software, I use FreeSSM. On older cars you can do it with no more than a screwdriver :P :

I have a hand held scanner (Purchased when I had a Legacy Outback). But does not seem to work on the autobox.

Hi

Drive the 5 miles to auto box specialist ( All in 1st gear kept it under 3500rpm ). They plugged it in but thought it was "D Sensor" but were not

sure, the replacement sensor is around £150 plus fitting etc. But the transmission specialist was not sure, so was a bit worried about spending £500 ( I am sure the bill will be that with vat, labour and new trans fluid etc ). Anyway I started up to get off the forecourt and no fault (ie box changes fine and no flashing gearbox light) I have since stopped and started a few times inc cold start and still fine. So not sure what to do. Would it be worth changing fluid/filter in the box, as maybe a bit of grit got lodged in the sensor and driving at 3500 in 1st cleared it!!!!

Mmmmmm, that's odd, the manual doesn't list a "D sensor " that I can see :fool: The working or not-working intermittency makes me suspect a bad electrical connection - might be worth unplugging, checking for moisture corrosion and then re-plugging the various sensor leads. Meanwhile get a diagnostic lead, download free SSM and if it comes back you'll be ready to find out what's really wrong with it.
