Is it possible to use both lines for the trans cooler to flush the trans? What I'm thinking is I can put the line that goes back to the trans into a gallon of new atf +4 and I can put the line that feeds the cooler into an empty container. My thought is that this will pump the old atf into the empty container and allow the other line to draw in the new atf. Running the engine while slowly shifting through the gears should allow all the old atf to drain. This way the trans pump does all the work.

I hope I relayed all the above correctly in comparison to what's in my head.



Does anyone know if this will work? the trans in question is the 30RH.

Bump
Anybody?

Here's the entire plan in order.
1. Jack up the Jeep and place jack stands under the rear axle tubes. One on each side.
2. Remove the drain plug in my trans pan and let the atf drain thoroughly.
3. Remove the pan and clean or replace the filter.
4. Re-install the filter and pan.
5. Add three quarts of atf to the pan.
6. Flush the system as described in my initial post until the fluid runs clear.

Theoretically yeah it will work, it's definitely going to take more than one person though!
