Changed fluid & filter in wife's Mustang with 6R80 today. Not a bad afternoon at all. Having 2 sets of hands was helpful at times.
Main tools were a 3/4" combination wrench, 10 mm socket, low range 1/4" drive torque wrench (from HF in my case), cheapie hand pump, and AZ Duralat TF507 kit (ordered online with SAVE20 discount code & free shipping), two disposable aluminum steam table pans (from Sam's Club in my case).
Here's what we did.
Put front wheels on ramps and let sit overnight. Put rear of vehicle on jack stands, still had very slight slope to rear. Noted factory gasket had a slight weep, but not enough to drip, by stains around pan lip in one area.
Removed dipstick plug & dipstick. Pumped out 5 qts. using cheap hand pump into empty 5 qt. oil jug before it lost suction.
Started loosening pan bolts at rear first to let remaining fluid drip into disposable pan. Removed bolts working toward the front, draining remaining fluid in disposable pan. Noted filter dropped into pan while loosening pan bolts.
Completely removed pan & drained into disposable pan. Removed old filter. Removed factory gasket and found flawed areas where seeping was noted, decided not to reuse "reusable" factory gasket.
Removed pan magnet & cleaned with brake cleaner. Drained fluid color was not nearly as dark / brown as seen on internet videos of drained Mercon LV, this fluid had lots of red left in it. Some grit in pan & on magnet but nothing excessive. Dumped fluid from disposable pan into a second empty 5 qt. oil jug. Total fluid drained was just short of 8 qts. using sight gauges on side of jugs.
Installed new filter, just a friction fit. Old seal came out with old filter so no digging in main suction bore. Lubed rubber gasket from AZ kit with ATF and used it while reinstalling pan. Torqued pan bolts to 98 inch-pounds.
Used hand pump to start pumping fresh fluid back in. At close to 6 qts. fluid started to spill out fill hole (into disposable pan thankfully). Installed dipstick & plug and took rear of vehicle off jack stands. Started engine and cycled through all gear positions leaving in each gear for several seconds. Shut engine off and carefully removed dipstick & plug again (hot surfaces nearby now). Used hand pump to add another 3 qts., minus spillage mentioned & leakage, to get just short of 8 qts. fresh fluid in to match what was drained & measured.
Final install of dipstick & plug, final check of pan bolts' torque with no leakage noted, and took car front off ramps.
Two things saved a lot of potential interruption time & hassle:
1. Having more than 6 qts. LV fluid on hand before starting the job (I now have 4 qts. leftover Kendall Versatrans LV from the case I bought).
2. Having a filter kit with spare gasket just in case there were problrms with the factory gasket. The AZ TF507 kit was the best deal I found on a kit with both filter & gasket. Filter was externally identical to factory filter except for one little prong on the plastic side which didn't matter one bit during installation. Showed Made in Thailand if anyone cares.
Should be good for another 40K or so miles. Mileage today was 43009.
Very nice write up good sir. Thank you
