yet ppl still had problem with their engine afterwards tho

God, it's always a tough call on trannys.

^ hence why i would like to find out

since we dont see a dozen of vehicles breaking down on each intersection

actually, from the year i worked there, engine flushes seemed to only cause one problems there:


leaks.


it for sure cleaned out the sludge, which the sludge inturn, was acting like a sealant for old + bad oil pan gaskets. now it was up to the judgement of the tech to sell it.

desperate sellers sell it to old cars, thus causing claims. a not so desperate tech wouldnt sell it. it all depends. not the product's fault. its more the tech's judgement.

sadly i've seen other shops (ie. dealerships and other chains) rip people off as well. i have enough stories to write a book! it's people/places that rip off customers for services/repairs that give the honest techs a bad name.

I work at a real shop, and we do trans flushes. sometimes trannys need new fluid, and the only real way to do it is with a flush.
we'll use whatever fluid the OEM recomends, always, and have never had a complaint. some are drain and fill, some will use a flush, if proper fluid and capacity specs are used, no damage should occur.

maybe lazy kids at poor people shops are doing it wrong, but don't look down on the trans flush.

Tranny flushes are good. But the way I used to do Tranny flush is by the "T-Tech" automatic transmission flush machine. It's basically sucking up the old fluid and dumping fresh ones :) :thumbsup:

so now auto tranny flush is ok now? hmm

it also depends on fluid/and shop.
some trans fluid you can just drain and fill.

long life trans fluid like cvt fluid are questionable too because theres a degredation monitor, but we seem to see a few CVTS that need replacement. the flip side too is that cvt fluid is like $30/l or something and it takes like 10L!

$300 for oil plus labor? wow
