Shifting to 5th?

[Dave1214]

I have a 2011 5.7 with 3.92 gears and 35s. With the gear selector in 5th my rpms are around 1800 at 55mph seems a little higher than it used to be. Is it only going to 4th or what?

When did you add the 35's?

You could try manually shifting up from 3rd to 4th, then to 5th and see if it shifts properly.

6 months ago. I tried it and it won' shift any higher than 4th but I have a check engine light now so I figured that will tell me what' going on
