Was playing with the truck this weekend. I have rarely used my click shift feature. My truck is a 2006 with the LLY. I assumed it had a 5 speed. But I put it in manual at 60 mph and it showed it in 6th. So I clicked down and RPM jumped about 300. I clicked down for 4th and rpm hit about 2400. The main question I have is did they put the 6 speed behind the LLY. Cause it sure seems I have one. I did think they did the 6 speed till the LBZ.
