    I took the pan off the auto trans today and I'm not happy Jan...:mad:

    First bad news was finding out that all but 2 of the bolts on the pan could be undone with my fingers... then I found there was no gasket either! That explains why there was fluids leaking all over my floor recently.

    Then I saw the colour of the fluid draining out...

    Finished getting the pan off, etc and here's what lies beneath:

    So what do I do from here?

    The gasket is still stuck to the pan, you can see it in the pics.

    It is not unusual for a trans that is overdue for a service to have that ammount of debris on the magnet. Is it slipping, not shifting or have any vibrations in it?

    Slipping when it's hot/warm. Still has drive if you manually shift down a gear or take your foot off the throttle.

    So is there a difference between a 'service' and a 'rebuild'?

    A service is just a flush, filter and new fluid. A rebuild is just that, rebuilt internals back to factory spec.

    Spend a few dollars on a service kit and fluid, may just be enough to stop it slipping.

    Fluid is dextron 3, it takes about 6-7 litres when doing a service, filter kit is fk1552 for a tt i think.

    Awesome, thanks. Think I'll look at a rebuilt auto or a conversion soon though.

    Doesn't a service also include adjusting bands? I've assisted with a service on a Falcon and part of that service included adjusting bands.

    Doesn't look pretty Keiran :(

    You could try a flush and refill, a pro-job to do properly, but I fear you'll need to invest in a re-build @ ~$2.5k or a 2nd hand tranny @ ~$500.

    Most importantly, fit an aftermarket cooler, as the rad cooling is insufficient and likely to be partially blocked with friction material (a major cause of failure).

    Right - new fluid, new thicker engine oil and filter, took her for a spin... can't tell if it's fixed it till Saturday I guess when I drive up to Sandgate for the dyno day. One thing's for sure, she doesn't slip in 1st ;) ! I'm probably gonna look for someone selling a recently rebuilt trans, otherwise it's a rebuild/conversion I guess :(

    Oh and I heated up the strainer while drying it which dislodged an awful lot of 3-5mm round chips of my precious gearbox :( so I'm guessing she hasn't got much longer to go...

    Well I just gave it a thrashing then and she's holding up fine....
    But if I don't run her, what am I gonna run? My Yaris?

    Hahahaah you're most welcome to, although I'm undecided as to whether to run or not. The drive up there will give me an idea I guess.
