E-450 tranny service?

2005 E-450 with a V10 and what I think is a 4R100. It has 31'XXX miles, and my father is asking what should be done. This is a Class B+ van front motorhome. Flush? Drain'filter, fill?

Thanks (not interested in asking the masses)

Its probably the 5R100 if I had to guess. You could certainly do a drain/filter job. A flush would probably be overkill for only 31k miles. The filter is probably 10-12 dollars along with a gallon or two of ATF and you should be all set.

Greg I believe it's a 5R110 not a 5R100. At least that's what our 06 has.

That's what I meant. Thanks

And there are two 'filters.'

One is a suction screen which is R&R'd by dropping the transmission pan.

The other is a bypass filter 'toiletpaper' in a bowl alongside the transmission.
Note that that bowl can be a tough nut to unscrew.

I have a 09 E350 V10 and the VIN shows that it has 5R110W-Hi Torque according to the manual, code "B".

What is the difference between the 5R115 and the 5R110?

Thanks, Larry

Hi Larry

The answer is torque capability, and apply the same to your 115.

I forget where I came upon this:
As for the 110, that represents 1100 lb-ft, but that's AFTER the torque converter multiplies engine torque by 1.9:1. That means it can take about 580 lb-ft of engine torque.
