at 70mph i run 2200-2300rpm on a 265/70/17 and i have a cammed 6.2 i avg 18.5mph highway and 15.6-15.9 city compared to my 14.5 in city i use to get and my 19.2 highway


that sensor is ONLY on the 4L70E not the 4L60E, i have pulle the tranny from my 08 and the tranny i used in my W/T which is an 06 tranny. it only has 2 plugs, the main harness and the VSS. the 70e uses 2 speed sensors like the 80e.


also if you are running a 80e the 4th gear isnt the same ratio as the 60/65/70e so your going to turn more rpm than you would with the other tranny. its so you can have a heavy load behind your truck an not burn up the OD clutch pack.
