sally being norty , any ideas ?

briggie · 15-01-2011, 11:15

coming home late last night after babysitting , sally coughed, spluttered and changed down a couple of gears even though i was on a relatively flat road ... then all of a sudden she changed back up and drove as normal , had no problems since, fuel gauge is showing just over half , temp is about halfway, no lights on dash , no smoke that i can see , could it just have been a bit of crappy tescos fuel or summat else ?

was it raining? perhaps it as just a bit of water in the air filter, but probably nothing to worry about, could have cleared an air lock, dodgy fuel etc etc

wasnt raining ,although it was a bit misty, im hoping its just a bit of crappy fuel , although would that make it change down then back up again once it was ok ?

Yes it would as the automatic gearbox will change down if there is not enough torque coming from the engine.

Any engine misfires etc affect the gearshift on an automatic due to the way the valve block in the gearbox is designed together with electronic overlays on newer gearbox designs.

On the older but more reliable fluid gearshift / valveblock designs this is particularly noticeable.
The later electronic designs tend to lock you into a get you home mode often sticking in an intermediate gear.

see, moisture!

i only mentioned it because a whileback, when i was having "troubles" with mine, i had the exact same thing happen coming up Brighouse road towards Ainly Top. Id driven all the way from Leeds, and hit rain in Fixby, so powering up that hill, i got the equivalent of what you describe, except i just lost power and spluttered. Everythign was fine when the rain stopped. I later found my I/C pipes were not tightened correctly, so figured water/mist/whatever had been sucked in. its never done it again since tightening up those pipes. On yours however, I think its simply as Mac describes.

Perhaps maybe it IS worth checking some of your pipes though? anything with an adjustable clip on it perhaps, and tighten?
