Volvo has changed its mantra and now says that the ATF should be flushed at the first 100K mile and every 50K miles after that. Better than the old 'sealed system' so you buy a new car or tranny!

Still, never use a machine that flushes a tranny. Most of them operate at a pressure that is too high and can ruin internals. Flushing at home takes less than 45 minutes and is quite satisfying.

I am sorry you got the tranny rebuilt, actually that it costs so much! There is an internal filter that can get clogged with sludge and could have been the problem. This filter can only be cleaned after tranny disassembly - WHY have a filter if it can not be cleaned? Come on Aisin, think about all of us shade tree mechanics who would be happy to pull off the sump and replace an easy to get to screen.

Of course, when the tranny starts to shift 'hard', the damage is already done and the parts are worn to the point where they need to be replaced. I would still have contacted Erievovo and replaced with a used.
