    Tranny woes

    Today I noticed that Aurora started shifting from 2nd to 3rd later than normal. Upchange could be helped by releasing gas pedal a bit. Upon arriving home I immediatelly checked fluid level and found it wanting It took appr. 0,7 litres to bring the level to max (according the stick 0,4 is the amount needed from low to full).

    On test drive it still seemed to be changing at higher rpm than previously.

    Fluid did not smell burned and colour was normal.

    So, have I cooked it? Is this something others have faced? Sign of tranny failing for good?

    1st, why are you asking about an Aurora in a Allante forum? 2nd, if an Aurora has a TV cable then I would suspect it as being adjusted too short. Given what you've said it sounds like an external issue, not a failing trans.

    Thanks! I still think you have a TV cable issue. They can bind or slip out of adjustment where it anchors to the throttle body.

    Carnut,

    Thank you for your help! Now, a Q from total newbie when it comes to slushboxes: how do I verify and if needed, adjust this TV cable?

    Hard to do via the printed word. A black cable comes from the transmission up to the throttle arm. As the throttle is moved this cable is pulled to alter the shifting points. Where it attaches at the throttle pivot there is a silver D shaped button on the cable. Using a screwdriver, press down firmly on this button. While holding it down slide the threaded black plastic cable housing back towards it. You will see serrations on the black cable much like threads on a bolt. Retract this cable till no threads show. Then release the button. With the engine off, rotate, by hand, the throttle to wide open. As you rotate the throttle, the cable will extend to its correct length. There will be resistance from the cable because its attached to a return spring of sorts in the transmission. Just make sure you go to fully wide open. It will make a plastic ratcheting sound as the threads slip past the cable housing. Now drive the car and report back. This cable if adjusted too short, raises the shift points, adjusted too long, it will shift too early and soft.

    Carnut,

    Thank you for very clear instructions!
    I do owe you a pint!!

    However, when looking under the bonnet, this is what I have:ImageUploadedByAG Free1379164953.031028.jpg

    Under the narrower black cover is normal wire going to d-shaped thingy.

    Only narrations that I can see are here:ImageUploadedByAG Free1379165103.062327.jpg
    and they seem to be part of the cable cover.

    Obviously, I'm missing something here!

    "Serrations". Go to any trans shop and they can adjust the TV cable in about 5 minutes. I said it was hard to explain but simple to do

    Again, thank you for your advice!

    However, solving this problem will have to wait for next spring. Autumn is here and I took Aurora to winter storage today.
