Trans fluid
What brand do you guys recommend? My truck needs this done desperately.
Do y'all just drain the pan and TC?
I've read some others that say to attach a tube to the trans cooler return line and pump it out and refill until you get clean fluid.
What do y'all think?

I changed mine recently. I dropped the pan drained the tc and the cooler. When I changed mine I switched to merc v to soften shifts. If you stay merc III use a name brand fluid stay away from the store brand crap

So merc V is better?
Just looking at how dirty the dipstick was, I just wanna get her as cleaned out as possible. I also plan on adding a bottle of Lucas to it when I'm done just for extra care.

I just did my 94 E4OD a couple months ago. Here's what I did:
-remove the pan, change filter (with Motorcraft filter, I've read others tend to fall out)
-empty contents of pan into wash bucket to measure amount
-replace pan and torque bolts
-fill with the amount measured earlier
-disconnect the return line. On mine, under the radiator just right of middle there was a rubber line connecting 2 steel lines. I connected a 3' rubber line from there to a bucket
-run engine for ~10 seconds at a time. You'll get a better idea of how much comes out after a few times
-turn off motor and drain contents into my wash bucket. It has accurate measurements in QTS.
-replace same amount.
I did this until I replaced 18 quarts. Then connect the return line and run engine to operating temp and top off fluid as needed. I used Motorcraft Mercon V but others have used Valvoline, Mobile 1, Redline or whatever brand you want. I went with MC just because. Good luck!

If you pull the pan off to replace the filtar why not just put a new pan on that has a drain plug in it. Here's the oem pan with plug for $44. http://www.fordpartsgiant.com/parts/...-7a194-ba.html
When I was doing the filter on mine I decided to put one of these on. Then I filled up the trans. Then every Saturday for the next 4 weeks I drained the pan and put some fresh fluid in. Only takes about 10 minutes. It's been at least 6 months and the fluid in my trans still looks brand new. I use the Valvoline Dex/Merc in the blue bottle. I thought about switching to Merc V, it does make the trans have a softer shift, but a softer shift means the trans spends more time slipping while shifting and creates more heat. and in a trans with 200k on it I don't want more heat.

I always heard if your not sure if its be changed before its not good to drain the torque converter, so I just drained my pain and changed my filter
