Guide to Tranny Fluid Swap?
Howdy and welcome! What tranny do you have first of all. You can determine this by the door jam sticker code under TRANS.
The 4R100 is code E
The 4R70w is code U.

Bought the truck used, and there is no sticker on the door.
There are 14 bolts in the tranny pan if that helps and a big letter S on the pan. There is a hump in the middle.
Does that help?

Although that procedure seems to be throurough, there are better and easier ways to do it. We use whats called a T-Tech transmission flush machine. It hooks to the cooler lines at the radiator, and flushes 99% of the fluid, whereas when you do it you'll only get the pan, and if you choose to do it the TQ converter. That leaves whats in the cooler lines and sides of hte radiator as old, so you'd get about 85%
It usually cost different amounts at different shops. I charge 89.95 for it, ford gets like 149.95 around here.

The end result for both is that at least 95% of the fluid is changed, and if you do it yourself you spend less $$.

It's all a waste of time if you don't change the filter. Personally I drill the converters and install a drain plug in them, but thats what I do.

The engine running flush will flush out the filter quite well also. The filters on those things don't get that clogged. The only reason I even bother changing filters in tranny's anymore is if they came from a junkyard and have been sitting, which would drop alot of contaminents in the filter. I mean, it doens't hurt to change it, I just changed mine on the navi, but only because its getting a more severe beating from the blower.
