10 speed transmission fluid change interval?

Update....If your truck has the RPO code MQB than you have the 10 speed 10L80 tranny. Yes you can service the tranny yourself. Check out this link of someone doing it himself. It's a good video, but I would see if you could not take out the O2 sensors and still get it done? A good mechanic can do it cheaper than a dealership.

I planning on changing mine every 20-25K and t-case and rear diff every 50K or so. I did both t-case and rear diff with around 5K on the truck to get all the break-in stuff out.

Not sure what your mechanical abilities are but the transmission is definitely a DIY type of thing. It seems more difficult reading about it but once you get into it it's not that bad, just messy. I didn't have to drop the exhaust so that's an additional steps and parts that I'm not familiar with.

How did you not have to drop the exhaust?

I have the 3.0 so I don't have the crossover pipe that the V8s do.
