So I am looking to drain my tranny fluid by way of dropping the pan on the 4t60-e. This will be my first time doing this so I want to be sure I have all the steps correct.

Loosen bolts
Drop pan with rear of pan hanging at an angle
Drop entire pan
Take down the filter and gasket ring
Clean pan
Replace with new gasket ring|filter
Tighten bolts
Refill with 8 QTS of ATF

sound about right anything I'm missing? Also is it safe to fill from where the tranny fluid dipstick is or is there another fill point?

It will tqake forever to fill via the dipstick tube. Fill it from the fill cap (upper left corner, next to the transaxel harness 20 pin connector).



anything I'm missing?
Wipe all the muck off of the pan magnet.

It is a good time to put in a quart of Lucas Transmission Fix.

Lucas Transmission Fix is a non-solvent formula that stops slip, hesitation and rough shifting in worn transmissions and completely eliminates most seal leaks. Use in any transmission for preventative maintenance. Use also in light duty manual transmissions to increase shifting ease and transmission life.

Lucas transmission fix is one of many snake oils that do nothing but lighten your wallet.
