I drained the pan, 2004 100 series. I got about 2.75 qts out. I went to fill and realized I wasn’t prepared- no dipstick and I didn’t have the right kind of transfer pump or the 24mm socket. I found a small 12mm plug in front of the linkage right above the pan and managed to get the new fluid in that spot- is this OK? I ran it 30 miles and seems fine- the overlflow plug is too tight to remove afraid I’ll break it. Any opinions if what I did was ok?
