[VAC] Yukon tow vehicle

[Robert Ramsay <rsramsay@xxxxxxx>]

We just bought a 2002 GMC Yukon with the 5.3 litre engine and the 4.1 
rear end.

We had been using our 1999 Yukon Denali to tow our 30 foot 1968 
Sovereign International.  However we towed in 3rd rather than overdrive 
as recommended on the list.

The new Yukon has a "tow/haul" mode that delays the shift pattern etc.  
GMC clearly says that it is OK to tow in "Drive" without having to be 
careful and tow in 3rd.

Has anyone had any experience with the newer GMC transmissions, and do 
you think it is safe to tow in "Drive" with a 2002 or 2003 Yukon?
