So I've been doing a 60k service on my 2020 and today I did the transfer case and transmission drain and fill. Some strange, but minor, things I thought I'd see what your thoughts are on.
First, the transfer case drain and fill plugs were extremely loose. I mean, I almost could have turned them without a ratchet if I just used the socket and and extension. They were not leaking at all, but they were nowhere near the torque specs. They hadn't even been torqued enough to get into the teflon tape on the plug threads. Just thought that was odd.
Secondly, when I drained the transmission pan for a "drain & fill", I opened the fill hole first and nothing came out, which I expected. When I drained, exactly 3.5 qts came out according to my graduated bucket; that was at pan/shop temp of 90F. When I filled, I only got about 2.75 qts in before it started coming out of the fill hole. I reinstalled the fill plug, heated the trans temp up to 105F, and it trickled out of the check plug like it was at the right level right away. I checked to make sure the truck and the pan were level as well. The only thing I can figure is that my graduated bucket markings may have been off? I drove with the scan gauge for 30 minutes after and the temp was 200 plus or minus and seemed to shift fine. Fluid was Toyota OE WS.
