I used roll on herculiner. It's flaked up overtime. Now I just spray the bare spots with black tractor implement paint.

 

okay so everything was fine with my jeep until this morning, I was driving out of my drive way when the check engine light came on. It was not that big of a deal until i realized it wouldn't shift into overdrive. Drove to work going 60 in 3rd runnin 2500 rpm, but i need help, what could cause this problem and how can i fix it!?

 

I'd start by reading the code that was set.

 

Allright, I was just wondering if it sounded like a fuse problem or tcm problem

 

Possible nss. Float your gear shift through the gears a couple time.

Also next time call in late to work. , doing 60 in 3rd isn't the best

 

Yeah i'm definitely going to take it easy on the way home. but I don't think its the nss because it was working just fine yesterday and it still reads in all the gears but overdrive, and it went on when I got to the end of my drive way, but just another thing to check!

 

I had an issue with my nss once and it didn't go above 3rd. It drove the same way you describing it. The problem fixed itself but I know my nss is on it's way out

 

Well earlier last month I had an nss problem and when I came back from Germany it fixed itself, it wouldn't start in park and id have to shift it into neutral and now od wont work so i hope that's it and i can just clean it or rebuild my nss. I just hope its not a 4th Blowout.

 

Thats funny, I always try to keep my speed/gear so I rev closest to 2500 (2300-2700) and I get best fuel mileage and less oil consumption. I have kept it there for nearly 4 hours straight many times over to notice a significent difference. If I pass 2700 it starts sucking gas more

 

I agree. When I tow my pop-up I keep the shifter in 3rd and run 70 down the interstate just fine.

The 4.0 likes higher RPMs.

 

Thanks! that also good to know! So ill be fine going home in 3rd runnin 60?

 

I also have 31's on stock gearing so it takes a smidge extra to get to the same RPMs but your engine will be fine at 2500 rpm.

 

I was more worried about the tranny not the engine.

 

same here but its only about 10 miles to home so if he can pull a trailer goin 70 i can cruise home goin 55-60, if anything I can stop and let her cool down too.

 

Running the transmission in 3rd is actually less stressful on the transmission than running in OD.

That's why I tow in 3rd. If I tow in OD in the hills the transmission will overheat.
