Firstly hi. This is my first post. I'm looking at buying a diesel auto sorento and wanted to know how I spot the difference between the 4 and 5 speed auto box without driving the vehicle. I understand the 5 speed came in for the 05 model year. I'm inclined to go for the 5 speed after reading reports of 4 speed failiures, especially when used for towing (which is what I will be doing). Thasnks.
