Will the real transmission fluid level check thread please stand up?

There's a lot of great tutorials here and a lot of YouTube videos, but I can't find one where someone does NOT say:

- You're doing it wrong
- You forgot a critical step

The DIRECT questions I have are:

1. After you get into temp check mode, do you pull the wire from the OBD? Someone said that puts the engine in the correct idle speed control mode.

2. Do you check the fluid in park or in drive with the e-brake on? Doing it in drive with the e-brake on seems sketchy to me.

I have a 2010 4WD if that matters.

 

Give this thread a read through again regarding temp check mode.

1) I dont think it matters, but its been a while since Ive done it myself. Easy enough to test
2) As stated in the thread above, check level in Park with engine running

Also note, the specified check temperature changed from 115-130F to 97-115F per T-SB-0129-08

 

See the thread below, note the specified check temperature was changed to 97-115F per TSB 0129-08 (see the tsb attached below).
