Transmission problem? Been driving her every day for the last month with no issues got in today and noticed a whinning sound coming from the auto transmission was fine yesterday does this mean its on its way out or could it be a top up? I know that gearbox oil shouldn't really get low unless theres a leak, this has just happened overnight which I find odd, hoping its something simple and not a gearbox :(

Push the little lever switch down and move the selector at the same time, it will allow you to move the selector without ign on or touching the brake.

 

Its at the base of the selector shaft at the front

is there a way i can post an audio clip on here? id like to post it so you guys can have a listen ......

Upload from your hardrive or via photobucket or youtube link

ok will do, the reason im gonna have to upload this is cos ive spent the last 2 hours trying to get this diagnostic thing to work, i have no A/T light anywhere on the car whatsoever, so i cant read any codes even if i did do the procedure correctly..

The AT light is left panel bottom of dash, maybe bulb is out or removed

Its following the revs and could be either the alternator, AC pulley or power steering pulley. I would disconnect the aux belts, then start up again if the noise has gone then you add one a a time, alternator, ac and then PS pump to determine which one. I could be wrong as its dificult to tell sometimes on a video, but it sounds too close to the engine to be gearbox related.

Thanks for the input groover, at first i thought it was gearbox but when i noticed the noise while idle and it goes after about 2 miles i thought maybe alternator,, ill have a look tomorow. thank you all for your help been fab ;)

Hopefully something simple :thumbup:
