Automatic Transmission quit
Hello
We have a 02 explorer with the 5R55W transmission.
We lost power starting up a hill. Now it has nothing. No reverse, forward.
Does not even think about moving an inch.
We can not find the dip-stick. Looks like a nut on top of the transmission that you stick a finger into or makeshift dipstick to see if it is topped up.
It probably has a cooler on it.
Never noticed a loss of fluid. Nothing at the bottom of the hill...
Any help is greatly appreciated
Kind Regards
James

Fluid fill is on the bottom of the pan. Brilliant engineering on Ford's part. 
Look for a large nut with a plug in the middle. Remove the plug, with the transmission in park and engine running fluid should be dripping from the hole. Ford makes a special adapter to add fluid but I squirt it in using a quart bottle with a nozzle tip pressed against the hole. Use only Mercon V fluid. If you see no signs of leakage and this happened suddenly I'd suspect internal problems though.

Fantastic Thanks
I suspect internal. Question is, torque converter or internals.
Think the reality is that when it stops working, the TCS or ESS would quit individually not as a set.
Powering up a hill seems like a converter, but...
We are a long way from a shop, almost 8 hr.
There are two converters so we may need to pull this one to get a replacement.
$450 at the parts places
$110 at rockauto... humm
guess if it is a test the $110. A lot of work for a test.

the bottom plug looks like a 13/16 socket with a 1/8 inch pipe plug in the center. I would pull the big plug and drain out 5 quarts of oil and see what it looks like. The big plug is a stand tube. You pump the 5 quarts in thru the 1/8 inch pipe plug to the top of the tube level, then add the small plug.

No way I'd go through all the work of dropping the trans to change the torque converter then put the old trans back up there. If you can pull it, chances are you can rebuild it.
Transmissionpartsusa.com has a kit, I used it to rebuild my 4R55E (same kit) and it's reasonably priced. I got the manual off ebay for about $12, kit was around $150 with a shift improver, and the result lasted two years of lots of miles including towing a couple 1800-mile trips. It was still going strong when I sold it over a year ago, and I see it running around town from time to time.
Automatic transmissions aren't as scary as some people think, generally if you can read, read a micrometer, and can pull the thing, you're able to rebuild it.

didn't figure anything but wiring for all of those myself
also can't really tell where the wiring is
looks like the front on drivers side near the top
does anyone know where they move or wiggle. where is the best spot to start looking.
yea maybe the connector just backed out. but i doubt it
frayed wires!
but where
thanks
