Well, there's going to be air in the system after you change it. Not much you can do to prevent that. Just disconnect the lines, remove the old one, put the new one in place, reconnect the lines. Then start the engine, shift the trans through all the gears slowly with your foot on the brake, back into Park, check the fluid level, and add as needed.





Make sure you use the right kind of fluid. If you've never added any before, the dipstick usually says what kind you should use. Once it looks full, drive it around a few minutes, then check it again and add more if needed. Best to add a little at a time, then wait a few minutes for it to settle, to make sure you don't overfill it.





The line with the pressure behind it should be connected to the lower fitting on the cooler, and that will push the air up, out, and into the trans case. The transmission case always has some air in it, but as long as your fluid level is right, the air gets pumped out from anyplace it shouldn't be.





Always check the fluid level with the transmission warmed up, engine running, transmission in Park, while parked on level ground, and wait after you add some to check it again so that the tube has a chance to drain, so you don't get a false reading.How do i change transmision oil cooler on dodge 2000 ram van 3500 heavy duty ? and get air out of system?
Unbolt the oil cooler, put a new one in, hook up lines,start it up and check the fluid and fill it up. Air will not get in it, because the transmission fluid circulates.
