well its not that bad, but under full throttle it has been known to go into neutral..hmm at least neutral is working.
a tale or automotive woe follows... due to badly worn discs i have been using the autogearbox excessively to gear down to avoid shudder..i have now replaced said wonky discs but appear to have developed transmission probs.
I opted for a ATF change hoping it might be a cheap solution- however despite my pleadings my mechanic swayed me to use dex 3.
no improvement in tranny problems (thats the gearbox mind you). i am suspecting that the fluid change only meant removing pan and fitting new 'kit' (whatever that is -im not too bright ) and replacing a few litres.
my question therefore is: 1) do i just bite the bullet and go for a new (old) gearbox fitted for 1100$ 2) have a full recon done (1100-1500$) 3) find someone in sydneys west to flush the full 8 litres (?) and replace with t-IV 4) where might i find such a person in sydney?

If you buy the fluid and take it to your mechanic, he should be able to flush it for you.
If you can get it reconditioned for $1500, I'd get it done. Usually a rebuild runs around the $2000+ mark.
Most places will be able to modify the shift kit and lift the stall speed of the torque converter at no extra charge. Don't let the rebuild use the old torque converter without cutting open, changing the one way clutch and re-lining the lockup band.
If there's metal fragments in the converter, splitting open is the only way to get them out. If not, they will wear out your rebuilt box in no time.

Thanks Anish. The problem has worsened somewhat in that i am now getting the occasional flashing 'TRC' on the dash with an associated blinking of the O/D light on the cluster display. Might this indicate that its an electrical fault or is it a sign of a mechanical problem worsening?
also what does raising the stall speed of the torque converter do?
oh and one other thing, re the quote of 1100-1500, the mechanic did say that he would be sourcing parts from old gearboxes where nec, but that it would be a full recon..is this a prob?

Excellent info so far, much much appreciated oh yep, the parts he was talking about sourcing were if teeth were missing off gears etc. oh and its thru an automotive shop. Mechanic says will include heavy duty clutch etc. He reckons he has been working on these particular boxes since the 80's on cressidas..and could do it 'with his eyes shut' should that inspire me with confidence?. Sorry for all the questions i just cant afford to get ripped off at moment.
Any more info on what lifting the 'stall speed' will achieve?

Lifting the stall speed --> torque converter locks up at a higher rpm. Gives more torque before locking up so you'll get more torque hence acceleration. You might burn a bit more fuel though.
Modifying the valve body --> same as installing a shift kit. Will give firmer shifts.

Thanks Anish, your advice is much appreciated. I dont want to be a bore..but it does appear that my transmission might have fixed itself (drove 2 hours, no probs). Now im in a dilemna...not sure whether to go ahead or ride it out for a few weeks. maybe the minor oil change helped? the transmission guy was of the opinion that no amount of flushing could fix my probs. Any thoughts? Thanks again for your timely advice.

Just wanted to let you know anish that youre right, it did sound too cheap to be true. Found that the bastards only fitted an imported box and did probably no work inside. Cost=1400. On leaving i found that the power steering pump was leaking fluid everywhere which i assume they have somehow inadvertently damaged...
