4L80E fill level
#15
Whenever I put my pan on, I marked the dipstick right where the pan meets the case. Can anyone tell me how much higher up is it where the valve body meets the case? Trans is an 01.

From my perspective the tube and dipstick hashes are irrelevant. After trans install, pull the pan off with the tube and dipstick installed and mark the dipstick at the level of the interface of the case and pan. This is the new "full" line. Some even advocate 0.5 qt over this mark. This is an absolutely critical aspect of install. I've read people speculate the reason GM put the full mark lower was to avoid the trans puking fluid and starting a fire. A stock vehicle won't see the G-forces a heavily modded one will hence no issues with fluid starvation with the lower level.
