Transmission and/or cooling system flush - how often do you do these?

[SoonerP226]

My son works in a transmission shop and he told me you should never flush a transmission. Simple fluid and filter change about every 50,000 to 65,000 miles.

To clarify, a fluid change is what the engineer recommended.

Toyota has a drain plug in the pan. I have yet to use it.
Any other mfg do the same? Btw, I've never "rep packed" wheel bearings either.

My Expedition has 307,000 miles and has the original factory ATF fill. I've never ever allowed the transmission to get hot. EVER.

I also have seen post 100K transmissions fail shortly after a fluid/filter change. Several of them. I leave them alone.

Never Touch a Tranny.

Jeep wranglers lag when putting them in reverse when the filter needs replaced. Common issue and quick fix.

As the GM of a pretty reputable service center, I can tell you that we have some pretty pricey repair bills go out of this place due to people following advice they follow on the internet from someone's brother in law etc. We do not service Scion, or I would give you a recommendation regarding your transmission (If you buy a BMW I am your guy).

The advice I can give you would be to first follow your owners manual service recomendation first. But also call a couple of Toyota stores and speak to the service manager about your car. Those guys can tell you what to expect based on what they have been seeing for several years and hundreds of cars. And getting a couple of opinions should get you a consensus. Then you can make an informed decision.

BMW has pretty pricey repair bills on everything. $800 headlight.
