An autiomatic transmission re-builder I know told me last week that he is seeing newer and newer vehicles in his shop with a/t problems.
Said that in the "old Days" he wouldn't see them until they were 8 to 10 years old, this week he has a GM vehicle in that is only a couple of years old, but 'miled out' of warranty. The a/t was 'fried' as he called it.
He does a lot of a/t work on Honda Odysseys and puts a 5 year 50,000 mile warranty on his re-builds, but in order for that warranty to be upheld, he requires that the a/t fluid is changed every year at his shop and the extra magnetic in line filter that he adds is also changed.
Most FWD vehicles now have no oil pan to remove and service the small OEM fluid filter (sometimes just a screen) inside, so those clutch pack, bearning and gear wear paticles are circulating around in the case like a grinding compound. The result is things get plugged up, start to slip, over heat and then...the tranny is toast.,
People obsess over motor oil change intervals but the a/t's get ignored and forgotten partly because the manufacturer calls the fluid 'lifetime'. Re-builders scoff at this and have some very unkind words about the whole a/t service info from the manufacturer. The more sceptical of them are convinced the new a/t's are 'make work project$' for their dealerships after the warranty is up. They say if that were not the case, the OEM would make the a/t fluid filter much better, accessable, and call for a fluid change service every 30,000 miles.
The a/t re-build is a labor intensive job that requires the entire Odyssey front end to be removed before the a/t can even be taken out, then the parts and labor for the autopsy and re-build runs into the thousands of dollars.
Then if your re-build has just one little thing that goes wrong during the complicated process, you are right back on the side of the road again.
So now, consider the health of your a/t before you worry about the motor oil...zall I'm sayin'.
