It's hard not to get the splash. This is how I've done it, with minimal splash. Starting at the rear of the pan. remove the pan bolts along the trailing edge of pan. Then loosen the side bolts gradually. Without getting to wordy, what you're looking to do is cause the pan to "hinge" on the front bolts. The trick to minimal splash is to get the gasket to separate, at the rear, with minimum pan travel. Also use a tranny oil drain pan or drain catch for a smaller pan. The drain catch looks something like a plastic trash can lid, with holes in the center, that goes on top of your regular drain pan.
Oh, and just buy a six pack of tranny fluid. You'll use close to that amount. when filling, only put in two quarts before you start her up. Or as much as it would take to show on the dip stick. Then while engine is running, continue to add until full. Don't poor it in like you would fill the engine. You want to poor in slowly to avoid any burps. Once you get it full, hold the brake and run the shifter through the gears several times, making sure that tranny engages. After you top it off, take it for a blast and check fluid again. After going through all of this, the car should be hot and fluid should be at the full hot mark. Don't overfill cause, as you'll find out, it's a B**** to drain.
So much for not being wordy.
