    I'm confused-if you removed the wrong bolt, where did the 4-5 quarts come from? And why can't the transmission be refilled thru the fill tube? Because it was never drained??

    I think he pulled the drain plug, and another plug thinkng it was the fill. Emptied the fluid then upon filling ran into the no fill issue. Then couldnt get the t45 bolt for filling off. So here we are, I like the 19mm bolt idea.

    I've heard of this happening so I was sure to crack the fill plug first. But, I used my impact to crack it. I used some extensions and a knuckle, hooked up the impact and did a fast squeeze and release. It spun it loose about 2 threads. I stopped, screwed it back in finger tight, drained, filled, started car, completed fill and then torqued everything to spec.
    I've found that the impact is always a safer bet in releasing ( barring a breaker bar) because of the burst of the force vs slow torquing. Never impact fill bolts with impact, tighten finger tight, then ratchet until resistance tight, then a 1/8 to 1/4 turn bump to finish if you don't have a torque wrench.

    the main reason why that fill plug's torx hole gets stripped besides from my case (accidentally using a T-44 on a T-45) is due to the fact that if a person is using a ratchet and an extension it's highly likely that the extension will be rubbing against the tunnel insulation which causes the torx bit to be not so flush with the center of the fill plug, which in turn causes the torx hole to get stripped.

    The best way I have found to prevent this from happening is when I was using a 3/8" flexible extension it worked every single time I was able to get the bit centered properly and that flexible extension did a good job not to rub much against the insulation and instead bent around it.

    Jim's 06 - I took the allen bolt on the front of the transmission off after reading some threads that mentioned that as the fill plug. I'm dumb enough to stop reading after I read that, but not dumb enough not to remove the fill plug first lol.

    CTSM - thats pretty much what happened to me. I didn't get my T-45 flush and paid the consequences.

    I'm going to heat up the area around the bolt as best I can with a propane torch, then try a flexible extension and get my T-45 flush, hopefully inside I have just a bit more area for it to catch onto.

    If that doesn't work I'll JB weld a nut to the end of it and give it a day or so to cure and try again.

    And lastly, I'll renew my lapsed AAA membership and call a tow to a local shop to have a nut welded on and have them finish the job for me.

    Let me be an example to all, read threads fully if you're not 100%.
