I would go look at the manual, but my rv is in 2 1/2 ft of snow drifts right now. Can someone tell me what the trans oil change intervals are on my 2006 E450 super duty? I have 37,000 miles on the odometer as of today. I'm the third owner of the rv and somewhere in it's life, it had a toad attached because the toad battery charger is still under the hood, and in my manual books, there is a Blue OX manual

Is it gas or diesel? On my 2008 F350 6.0L diesel (same engine as 2006), oil changes intervals are 7,500 miles for normal usage, or 5,000 miles for heavy usage.

If the vehicle is used primarily for towing (as mine is), then the 5,000-mile interval is recommended.

He has an E450, probably a class C motorhome and with a V-10 engine. He is asking for the transmission oil change interval, not an engine.

When we had a Class C, at 10,000 miles, I changed the transmission to Mobile 1 synthetic oil and added an auxiliary external transmission oil cooler.

Since oil change are cheaper than rebuilding transmissions, I went with a 50,000 mile filter and oil change interval.

The manual for my '06 F350 states to change the transmission oil at 30000 miles, along with the inline filter. I change it sooner 'cause the truck is used for towing mostly and west of me is the rocky mountains.

My '05 F350 6.0 also calls for a 30,000 trans oil change interval.

I am shocked there was no auxiliary external transmission oil cooler from the factory !

I would like to see some pics of your installation,

That seems kind of short, but a Class C IS pretty heavy !

I am not familiar with that transmission, but it it did nor have a drain plug from the factory, I would certainly install a magnetic drain plug the first time the job was done. Don't worry about changing the filter. They really are good for life of the transmission. Even though you are not completely draining all of the fluid, I would not worry about that either.

The recommended Motorcraft ATF is either 100% synthetic or at least semi-synthetic.

I have changed the transmission fluid three times in our Class C on the 2003 E450 chassis using this procedure. Easy job in the driveway. Currently at 112,000 miles with no transmission issues.

Theoldwizard1,
The pan does have a drain plug so draining is easy. As for the filter, there is an inline filter between the transmission and the coolers that must be changed when changing the fluid. I was not talking about the filter in the pan. I know that it does not need to be changed.
