And if by some strange quirk, there is no drain plug ..... disconnect the top transmission line at the radiator, put a hose bib end in place, attach hose, put other end in big bucket, start and watch and when fluid stops coming out, turn off.
You really would be best served if you can get a complete change in, all 12 qts.
My '95 had the plug as did my '98 and '00 CVPIs (I'm pretty sure my '01 Merc does, but I know that we added plugs to some later cars and my '01 might have been one we added a plug to, I help a buddy at his shop some times when OD). My issued '06 CVPI does not have a TC drain.
If not already done, now iis a good time to add an additional cooler in front of lower radiator, plumb it between the top radiator fitting and the return line back to trans. I used several clamps.
$180 for enough to change fluid, that's just obsene.
Yes, use Mercon V. These 4R70W transmission's TCs slip variably according to commands from the PCM, and when they first came out, Ford went through several formulations of Mercon trying to solve shudder while allowing the clutch facings to slip smoothly upon command (please excuse my crude description). Mercon V is the result of those several years worth of trials and as far as I know, now recommended for all 4R70W transmissions.
Got my '95 back in May with 52,xxx miles and first drive, it shuddered really badly at somewhere near 35-45 under light throttle like you describe, only bad, and the "wife unit" thought I'ld throwed good money away. Picked up 14 quarts Mercon V (I bravely told wife "no big thing, probably original fluid, and I knew a complete change took 12 in the police cars, I got extra for the cooler, used 13 total) and a filter kit and aux cooler kit, changed it all out, it never hinted at shudder again, not for a moment. Difference was like night and day.
A fine pair ... ... and whatever you do, Have a Safe Trip!
