How do you get a full exchange? is a pump required or is there a drain plug on the converter?
Here is what I did:
1) drop the pan and clean it with solvent (I used brake cleaner) and let dry. Clean off magnent and replace.
2) adjust rear band and replace filter
3) replace pan and adjust front band
4) pour in ATF to match the amount that came out from dropping the pan (mine took approx 6. 5 qts)
5) then remove the cooler line closest to the rear of the truck (this is the one that contains the fluid returning to the trans from the cooler)
6) attach 5/8" ID hose to cooler line with a hose clamp, then route into bucket
7) start truck and put in neutral (no fluid will come out when it is in park)
8) run until 4 qts comes out
9) shut off truck
10) pour in 4 qts
11) repeat steps 7-10 two more times (so a total of 16-18 qts of fluid are replaced).
12) reattach cooler line, start truck, take it for a long spin (10-15 miles) to get trans fluid up to operating temp, then check and top off as necessary. Make sure you DO NOT overfill it.
Good luck.
