I know this has been beaten to death in other forums, some consider and power flush for the transmission to be the best thing since sliced bread, others consider it the mark of the devil. I'd like toe ExPo take of it, particularly as it related to the Isuzu Trooper tranny.
on the good side:
1- It flushes *all* the fluid, as opposed to *most* of the fluid in a pan drop
2- It helps get those lil' chunky bits of varnish off the valves & galleries in the trans.
On the bad-
1-Those lil' chunky bits can clog small ports and galleries causing a massive failure if your gunked up enough.
2- its more expensive than just dropping the pan
My personal take is if you have a *brand new car* and start with the flushes every 30k miles, you wont build up enough solid bits to worry about, but if you have a vehicle you picked up with over 100k miles and dont know the maintenance history of (like me), its questionable.
Do YOU do it? Why? How often? Is there a way to clean out an older tranny enough where its safe to do one?
