Hybrid Transmission - how to check fluid level

[BamaDawg]

Does anyone know how to check the transmission fluid on the 2013 GMC Yukon Denali HYBRID? The manual does not tell you: when running or off? in Park or Neutral? They have unique transmissions, in that they have an extra pump to run when the engine is off. When I check mine and the engine is running and tranny is hot it is fine on the hot *** cross marks. When i check it cold, it is well above the hot mark but in normal transmissions it should be lower not higher? Does the extra pump dump more fluid in the pan? You would think the hybrid specific manual would advise this but no? HELP. Anyone with a Hybrid know or see this?
