Auto Transmission= Castrol TQ-DII
Front and Rear Diff= Castrol SAF-XA (rear diff LSD additive as well)
Transfer case= Genuine GM product.
All above done every 20,000's.
Engine oil= Mobil 1 and filter every 10,000ks.
Its like a cheap form of insurance when you think about it and all up not that expensive.

Tim, did you mean to say Castrol TQ DIII ?
Dexron II became extinct with the Trimatic LOL.
