4r70w interchangeability options
Ok, im a huge junkyard prowler and fan when it comes to parts that i need for my trucks. One very huge question i have is what automatic transmissions from others ford will bolt up to my truck?
Mine is a 2000 F150 5.4L 4x4 non 7700 gvwr type 137,000 miles
the transmission began by not shifting into overdrive, then moved on to having nothing but reverse the next day, to not going anywhere at all! im asking about interchangeability options being that i dont have $2000 to get mine rebuilt, and not a single junk yard near me in WA state has a 4r70w for a realistic price. $1300 dollars used is rediculous.
i have seen posts saying possibly one form a 4.6l
or one form a explorer possibly
as well as i think the e350 has one...
my main concern is finding another vehicle that has a transmission with the same plugs as mine as well as ability to handle the power, so i can offer the junk yards more vehicle options to search for. most of them just hear 2000 f150 and instantly say no..
please can anyone help me out?

Also the 4R70W from a 5.4l powered truck is built heavier internally than a 4R70W from a 4.6l powered truck.
How much heavier of a build i do not know, but there are some differences. But as previously stated they will bolt up and work either way.
One thing about using a 4.6l converter with a 5.4l engine. It makes for some sweet burn outs and reving power, but i did notice that i was loosing some bottom end grunt out of the whole when towing. I think since the 5.4l engines peak torque is at 2500 rpm, and the 4.6l stall is around 1800 rpm, you are missing some of the power band of the 5.4l.
Just my .02

Johnny, how long would you say it would take you to rebuild your own trans? Its the only thing that I have never rebuilt before and I'm thinking of tackling it in the very near future.

Thanks for the info! Cursing? Whats that? LOL Is it "specialty" tools that you need? Any book you reccommend?
Thanks

You'll need a set of slide hammers to pull the front pump, and the only manual I'd recommend is the Helms 4R70W manual. It's expensive, but it's detailed like no other,and doesn't miss anything.

Looking into this as well. I'm going to start a buildup of my 5.4L this summer/winter and I'd like to find a blown 4r70w or 4r75e to rebuild with higher end stuff and a shift kit. Is there a comprehensive parts list with Ford numbers so one can just order all the stuff needed to do a full rebuild? The 4r75e is another option but IIRC there are a few things you have to do to get it to work in place of the 4r70w. What those are I need to do some more research...

Whatever you do-DO NOT use any aftermarket clutches that are not OE spec. Those crap Alto Red and Raybestos blue clutches are not any good. There is absolutely no need for any type of "shift kit" in a 4R70W.

05/06 Expeditions had it, I think the F-150s do too after 2004 but not completely sure. Yeah it is stronger and shifts smoother.
Good to know, I would only use OE stuff in a trans anyway. Do you know if anything crazy is required to make the 4R75 work or is it basically a bolt in upgrade? I know of at least 2 people on another forum with their 4R70Ws swapped for the 4R75 but I can't get ahold of them through PM.
The 4R75 is stronger and has all of the better/upgraded 4R70W parts in it.

It's essentially the same trans, but it has many internal updates that make it more durable.
