when to change the trans fluid?

[Colton 03]

06 6.0 auto trans with 110,000 miles wondering if i should change and what is the best way to do it. through the dealer?

I too have a 2006 6.0. I had my Ford dealer perform a transmission flush and changed both transmission filters at around 22,000 miles. I did mine early to flush out the break in debris. You are longgggg over due for a transmission service.

Filter change every 30,000 miles on trans.....

Drop pan change the filter and the external filter and refill.

There is no need to change the internal screen, it won't clog up. Just change the external filter, drain via drain plug, and refill. You won't get all the fluid this way, so do it again in 15-20k and every 20-30k from now on.

Guess Brian at BTS is wrong.....not! Change the filter. Have you ever pulled one to see how incredibly fine the screen is?

I changed my internal filter at 70k and it was spotless, same with my dad's at 55k.

You can also do a flush in the driveway if you prefer. I think there is a writeup somewhere on here about it

id change both filters with that kinda mileage.

but i normally just change the external toilet paper looking one and flush the lines a little bit. and use the ford fluid
