    Oh well I just did a full transmission and torque converter swap too so everything is pretty well drained
    I was thinking about how it kind of gets some resistance when the axles attached, wasn’t sure how that affected it

    Don’t shift through the gears without the driveline in place. The gears stay moving without a driveline/brakes to stop them and will grind when you switch from forward to reverse or vice versa. It will also chew up the parking pawl going from drive or reverse to park.

    Just keep throwin' money at it.
    Performed this tonight. Thank you for the write up.

    I messed up though and shut off the truck when I went to check the fluid. I drained out just under 3quarts. I added in the extra 1/3 quart and when I opened the plug nothing came out. So I added more. Now I am wondering if I might have overfilled the trans since it was not idling at the time. I added in an extra quart and nothing has come out yet. Should I drain more out at this point? I am letting it cool down to run the check again.

    It doesn’t matter if you over filled a bit. The purpose of the check procedure is to assure you have the correct level. Follow the directions, check it when the temp is correct and the excess will trickle out.

    If nothing comes out, you need to add more and repeat the check.

    Thanks. Let it cool down a bit and ran through the process again. Temp light went solid, kept it running and removed the fill plug and nothing came out. Turned it off, and added more. I took out around 3 quarts and so far I have 5 quarts in with nothing dripping out. Seems like a lot of fluid compared to what came out.

    Are you sure your pulling the overflow to check and not the drain? You should get apx 3qts out the drain not the overflow.

    There are 3 holes. Fill, check(overflow), and drain.

    Its been a long week. I was checking the fill like a diff and not the overflow. This makes WAY more sense now. Thank you.

    It is always a good idea to keep track of exactly how many qts.and ounces you take out and put back in.
    You either need to make or buy a graduated container.

    Keep track, yes, but not to do the check, verify level - no guarantee it was filled correctly to start

    I hope someone can advise me.
    I tried many times to get my truck in trans temp mode and the trans temp light came on and stayed on, no flash
    Could it be I am already up to temp?
    I am confused also because I'm seeing 2 different temp ranges on this forum.
    Do you know which one applies to a 2010?
    Thanks everyone
    Regards

    Read the directions on page 1, there is also a video. It is not difficult to do.

    Here is a snip from page 1:

    Several of the dash warning lights will begin to flash (normal). Then shifting from "P" to "N" (pausing briefly in "N"), began a series (six shifts) of "N" to "D" to "N" cycles with the shifter. After the 6 shifts are completed the red AT TEMP light should illuminate for 2 seconds (important to note). Place the AT back into "P" (light will illuminate again for 2 seconds) and let the truck idle to warm the fluid. It is important to note that the light illuminated for two seconds as that verifies that the truck entered "Temp Check Mode". Without this verification, you may wait all day for a light to illuminate without the truck actually being in mode.

    When the AT TEMP light illuminates constantly, the fluid is at the correct temperature for checking. If the AT TEMP light should begin to start blinking, this means the fluid temp has surpassed the allowable range and you must shut off the truck and let the system cool. Retry again after a 1/2 hour break.

    Thanks for your reply
    I did read the first post and this whole thread
    I also watched the video .
    Every time I've tried it, the trans light comes on and stays on.
    Regards

    Loud as hell URD exhaust!
    Fluid temperature is too hot. Let cool several hours maybe over night and try again.

    Thanks
    That's what I suspected, I really didn't think it ran that long.
    Must be because of the heat in the garage.
    Thanks for replying

    Quick question(4.0 5 speed auto) I wanted to check my trans level so last night I put in an extra quart and this morning I got out an extra quart. I didn't take the truck for a ride after I put the quart in it but I idled and shifted the gears. My question is does the tranny fluid circulate without the truck actually moving or did I just remove what I put in the pan?

    Yes, as soon as the engine starts it is pumping fluid.
