#68rfe transmission full#
I check mine after it's reached full operating temp and sitting on level idling in neutral. I happened to run into the guy I sold it to maybe 15 months after selling it to him and he said he'd racked up another 100,000 miles (also as a hot-shot driver) and still hadn't had any problems at all out of the truck.Ĭlick to expand.With the Mag-Hytec pan it takes between 10 and 11 quarts, on my 4x4 model (I don't know if the 2x4's are any different or not) I initially put in 10, check it, let it idle in neutral at least 10 minutes, check it, take a short drive, and always end up putting in the 11th, then after a longer drive of at least 50+ or so miles I sometimes even end up adding some small portion of a 12th quart to bring it to just barely over the top of the upper hole. My last truck was a 2014 and I ran it to 470,000 miles following the same pattern with the Mag-Hytec pan and the same filter/fluid change schedule and it was also still going strong when I sold it after I bought the 2018.
#68rfe transmission upgrade#
In fact I have never had any problems at all and never had to do anything but change tires and brakes on this 2018, though I did upgrade all 4 of the factory rotors to the Hawk Performance "Talon" Rotors (awesome!) and Power Stop Carbon-Fiber Ceramic Brake pads which stop great, keep the wheels spotless (nice!) and seem to wear MUCH longer than anything else the parts stores sell. My transmission has always ran cool (about 177 degrees) and now at 332,000 miles is still going strong so far.

Then I changed fluid/filters again at 60,000 miles, and since then have changed the fluid twice more at 140k miles and 220k miles and 300,000 miles. I use Valvoline ATF+4 Full Synthetic fluid. The first week I had it I ordered a Mag-Hytec deep sump transmission pan with the drain plug in it from Amazon (I will share the direct link at the bottom) and I changed the fluid/filters after about 4k miles when I put on the new pan because I did one lightly loaded trip while waiting on the pan and that was good because it gave just enough time for any stuff left over from the manufacturing process to get caught in the filters (also changed the engine oil/filter early the first time for the same reason). I hot-shot with mine in my 2018 2500HD Laramie 4x4 so 95%+ of my trucks miles are towing, sometimes heavy stuff, and my truck now has 332,000 miles on it and I'm still running the original 68RFE and never had a bit of problems with it.
