So how many miles on your truck, if you are getting close to 30K you are ready. Make sure you get a good filter kit and i alway recommend a better ATF, like a synthetic or at least a good additive like Luca to keep the old tranny HAPPY.
There is a trick to refilling the transmission. If I remember right it takes about 6 qts. of fluid and only the first 4 or 4 and 1/2 goes easily. after you get all you can in you must start up the truck, go back and forth between drive and reverse for just less then 2 minutes, then go back and add the rest.
Yes you do fill thru the side plug on the pan.
Don't forget to due the diffs and t/case and just in case you haven't thought about it, the power steering fluid and the brake fluid. I use synthetic or a GL6 rated gear oil and synthetic p/s and brake fluid, they hold up better.
You might also inspect your front drive shaft where the double cardan attaches to the t/case, no jerks, change them cause they will break and it will cause either t/case or tranny case failure.
See what happens when you ask a simple question.
