Looking at a 2007 loaded mega cab. The ad says 5 speed auto. Is this correct?I thought all the 6. 7's came with the 6 spd auto. I haven't went to look at it yet,but had a couple questions on what "problem areas" to look at. It has 30000 miles,and they're asking $39,000. is this a good price? Any input would be appreciated. Thanks.
