The FSM says it all. Thanks for the photo, TooMany.
Tip: You need 15+ minutes at freeway speeds to really get the temp up to normal. Five minutes tooling around town isn't enough. You want the trans HOT to check the level. DO NOT add any fluid unless the level is below the "min" mark. Only add 8-16 oz at a time. Overfilling is worse than underfilling. It is very hard to get an accurate reading on the dipstick, especially after adding fluid. I'll usually wait a few days and try again, to let all the liquid in the tube drain out. This seems to help, but it's always a pain. For some reason, my '93 dipstick is just awful to withdraw and insert. My '87 slides in & out almost as smoothly as the engine oil dipstick. Go figure.
BTW, you'll notice some odd behavior when the level gets about a quart (32oz) below the "max" mark (i.e., half-quart below the 'min' mark). What usually happens is you get a flare/clunk on the 4-3 (or 4-2) downshift, when slowing from say 50mph down to 15mph, and then accelerating again. BT, DT, on two different 722.x trannies.
