To get ALL the remaining fluid out you need to drain the torque converter, trans cooler and all related hoses. A tranny flush. When I put my MagHytec pan on, I just replaced the fluid that came out with Mopar ATF. What condition is your oil in?
I dont beleive you can use the Amsoil ATF in these trans just yet.. according to their website.Oil is only about 8,000 miles old. Had a mechanic flush it in Sept. and put the factory pan back on. I've had a small drip ever since and decided if the pan was going to come off, i would go ahead and put the MagHytec pan on with Amsoil Universal ATF. Just didn't know if I could drain this at home with basic tools and limited know-how.
I noticed an article in Diesel World this month with a guy using Amsoil Universal in his 68rfe trans. I then emailed Amsoil today and got their reply that the Universal is suitable for the 68rfe. It is also posted on their website now as well.
you really can't without the proper machine to do it.But how do you get the remaining fluid out once the pan has been dropped? Its my understanding that the pan fluids is only about 1/3 of the total that is in the transmission system.
I swapped my pan out for a PLM about 20K miles ago. Didn't totally flush it. Refilled with Amsoil Universal. Absolutely no tranny shifting or other issues using the Amsoil. Either way - Mopar ATF +4 is really good stuff if you decide to just use regular tranny fluid.Although I know there was still fluid in the TC it took 11 quarts to get it back to full (stock pan). I think thats an indication that most of the fluid in the tranny cooler drained.
