We do have some real mechanics down under who can think, trouble shoot, adjust and fix rather than just replace regardless.
I cannot believe as I am sure you can't some of the botched transmission overhauls reported from North of the line and the money which changes hands for such poor workmanship is something else. They would get a short shift down this way. N.B. accidental pun!
Regards Harvey and all the best to you Brunette.

Sure Trevor, we down under are progressing in the same direction with our service people. We use to train our mechanics in all aspects of automotive technique, with all the hand skills that called for. Now days because of the economic climate, less tradesman are taking on apprentices, so it has been the motoring organisation that are doing the training. It's not in their interest to teach them skills that are not necessary in their work, eg. "follow the troubleshooting chart and replace the part, see if it fixes the problem, if not try replacing the next bit."
I've been at it for almost 50 years now and I don't get fazed out by what people say, I run my own course.
With Brunette's gear box problem, the first sign of 2nd to 3rd gear flare, points to the band needed adjusting, the band is applied in 2nd and is realised in 3rd and the high clutch is applied, if the band is worn it releases too early and the engine. RPM rise till the high clutch applies.
As James said " A tranny is a tranny is a tranny" (gee wish I had said that). The SVX auto box is the same 4EAT that is in the Liberty and Impressa, sure it has more clutch plates and some other mods, but it is the same. Any good auto tech that can work on them can do a SVX unit.
So why does the SVX have trouble and the others don't have as much? The high diff ratio places more load than the others, Also because of the high ratio, driving in D around town, means that gear box RPM is very low less that 2000RPM, the pump output is low, cooling is reduced, and the torque converter because of the high torque multiplication needed produces a lot of heat. A recipe for failure. Shift back to 3rd the engine RPM rises to around 3000, and the box is happy.
Anyhow rave, rave. I hope Brunette takes it to a auto trans specialist for a service and band adjustment,cost about 200 to 250 and you may get another 145,000kms out of it.
Harvey.
