Shift points
1 Attachment(s)
So, I've had my Jeep for about a year now but I've never looked at the suggested shift speeds in the owners manual. I've been driving a standard as long as I've been driving and just drive by 'feel'. But according to the book I'm pretty much always a gear too low. I'm sure that I'd get a little better gas millage if I went by this. Does anyone follows these shift points?

I had to really think about it -- but those are probably really close to my shift points for both cruising and accelerating. The thing is, I have rather short gearing. Not sure I can picture doing that with 3.21's on 32's.

Yikes - It sounds like you have 3.21's?
Short gearing is annoying on the opposite end of things - I gotta row like crazy everywhere I go! When I know I'll be cruising for a bit on secondary roads, I'll often grab 6th at 35mph. On flat ground, 6th is still usable to just under 30mph. (4.10's on 32.6" tires) I honestly wish I had 3.73's. |

I never even opened the manual, but that looks almost identical to where I have been shifting.
Good to know. |
I have 3:21's and the 3.6L. I never shift by speed. Always by tach. I usually shift at 2500rpm and like to keep it around 2000 while cruising.
Only exception, is 6th gear. I'll shift into 6th on the hwy when I hit 65mph. I find I get the best mpg this way. I have 32's on it and don't plan on going bigger. 3:73's are in my future. THis thing is just too much of a dog with the 3:21's. 1st gear and reverse suck. |
I have the 3.73 on my 2012 and constantly find myself skipping gears on flat roads. I start in 2nd, then to 4th and to 6th at 35 to 40 mph.

6th gear at 35-40mph? You have to be turning under 1500 rpm. Probably closer to 1200. Not good for the motor or your fuel economy. |
