It just really comes down to choice!! The best way is doing both ... drop pan / change filter / full fluid exchange
My choice: Have the dealer do the pan / inspect / install new filter at 30K. The most waer will come in the first 30K anyway. At 60K ... I will just do a fluid exchange.
So I really don't see a need to come back with a snide comment ... "well good for the dealer" type of thing. Do a little research .... no need to be rude!!
Transmission Flush vs. Drop Pan/Filter change method??
[quote author=dealer1 link=topic=2188.msg12613#msg12613 date=1176676019]
I have been doing transmissions for over 30 years and I would definitely recommend pulling pan and doing it right.Why would anyone change fluid without filter?
Changing ATF Fluid in a E4OD and 4R100 transmission .: Articles
The 4R70W transmission system holds about 14 quarts of ATF. � The 4R70W uses MERCON V, and the MERCON V can be used on older 4R70W transmissions that were factory filled with MERCON.
I replace the transmission filter every other fluid change. Note that Ford does not recommend ever changing the filter. I've opened filters with over 300,000 miles that were not even close to being clogged. �
Don't buy a new pan gasket. The original is reusable.
A 10 foot length of clear tubing and one hose clamp, sized to fit over your cooler hose. There have been different size cooler lines over the years, so check before buying!
If you don't already have a special funnel that fits into the transmission dipstick tube, then you will need one of those, too.
