Im with you. I did'nt want to mess with a plug install. Im not sure about your 07 but I paid around $40 for my 04 from Tasca Ford. Not sure about the Dorman but it is cheaper

I purchased the commercial pan with the plug built in, replaced my stock pan, reused the stock seal, no problems. Getting the original pan off was a semi-messy PIA, but you just get a cheap hand pump from HF suck out as much fluid as you can from the tranny, and bobs your uncle.

I have a clean stock pan for sale if anyone wants it...

I ended up buying the pan. Came in yesterday and I swapped it out. Truck has just over 95,000 miles on it. Dropping the original pan wasn't too bad. I used a big kitty litter box under the front and removed the front and side bolts until it stopped dripping. I used a tiny hand pump and removed the rest before lowering the pan. The magnet was absolutely nasty! The fluid itself wasn't much better. Looked like red-ish brown syrup. The yellow plug was in there so it was the first time. Changed the filter and added new Valvoline Mercon V rated fluid for the first of a few flushes. I am going to drive about 500 miles and and re-drop the pan and fluid again. Do that until its all clean. So far the truck shifts/drives way better!

Mine should be here Monday. I picked up ATF and some Rotella yesterday along with a few cans of brake cleaner. Also have a new filter inbound even though I replaced it 15k miles ago.

Swapped mine tonight. Pumped the fluid out through the thermostat housing so it wouldn't fall all over me when I pulled the pan. Still got plenty messy. Filter replaced too. Can't wait to pull the plug at my next oil change and then fill it back up.

Why not just have a good transmission shop do a complete low pressure flush and get all the fluid changed, instead of just 5 quarts? 2007HarleyDavidson's post had my eyes wide open with the condition of his fluid; he mixed 5 quarts of clean fluid with about 5 or 6 dirty quarts. Continuing this process of dropping the pan only repeats mixing dirty with clean; as soon as you start the truck, the transmission pump will contaminate the clean with dirty.

I didn't catch if the dorman pan also increased fluid capacity? What are the thoughts here about a pro low pressure flush? That's been my question as I've read about 100 posts on dropping the pan and changing fluid. Sure seems like you're not doing the new fluid any justice if you don't get all of the old out. Seems like low pressure flush would be best of both worlds.

I've used AAMCO for years on several vehicles, including two F150's (my past 2005, and my current 2007). The 2005 was done at 80K, and my current 2007 was done at 110K (when I bought it; I don't like assuming any previous maintenance). In both cases, they dropped the pan to examine its condition, used the low pressure flush, replaced the filter, and off I went. Never had any ill effects with a low pressure flush, but I will also state that my transmissions were in good order prior to the flush. If you have issues with your transmission, a flush (or any fluid change) is not going to resolve any or all of their issues.
To me, dropping the transmission pan and changing the filter and adding about 5 quarts is like draining only 3 or 4 quarts of engine oil and topping off; better then never changing any of it, but not a complete fluid change.
AAMCO charges me $160.00 to do it, and they use a full synthetic transmission fluid (as Ford does).

I went to a local transmission shop that I trust today to get their opinion. They were adamant that they never flush, simply drop pan, change filter and do an inspection. Their explanation against the flush is that nearly all used transmissions will have some amount of debris floating in there and a flush requires it to egress through the rest of transmission, potentially getting stuck elsewhere and causing new problems. For what its worth, that was one shops opinion. Also, the owner didn't think a larger capacity pan bought more than 3 degrees, although I'd be interested to see real results from people here with monitoring devices before and after capacity increase.

I didnt add capacity, but my pan drop, with filter and 4 quarts and drain/fill with 4 qts since then twice more, results in my temp never going over 150 on my 25 mile each way commute.
