Hi all. I recently purchased a 03 Mitsubishi Montero, My plan was to swap all the fluids before winter. I've done front/rear diffs, transfer case, and engine. My original plan with the transmission was to just drop the pan and replace filter/fluid. On this particular transmission there is a drain plug. After seeing the condition of the fluid come out I've decided to do a full drain and replace with Amsoil SS ATF.
Is the following procedure correct?
1. Refill the same amount of ATF drained from pan.
2. Pull return line at cooler.
3. Shift to neutral, turn on engine for 30 seconds to 1 minute. Drain return line into container.
4. Drain transmission pan via plug.
5. Add same amount of ATF that was previously drained.
6. Start engine in neutral. Shift through all gears.
7. Wait for fresh ATF to come out of return line.
8. Shut off engine. Put everything back. Refill remaining ATF.
9. Start engine, inspect fluid level after engine is warmed up.
