AT what rpm should I shift during normal city driving. i've been doing in around 3000 rpm? Also when I was wheelin in a forest the other day my clutch got so hot it was a ctually smoking out the openings. I have not had problems since. Is it shot or did it just overheat?

Peace

 

I never really look at the rpm when I shift? I go by feel of the engine...but I'm guessing at 2500-3000 should be ok However, don't ride your clutch, which I think is what you're doing.

 

i tend to shift around 2k in town but im a slow driver

 

Back when my JK was stock, I went by the manufacturer's recommendations, as given in the owners manual. I made a mental note of the corresponding RPM's and now that my JK has a different tire/gear combination I just use my tach to shift. My stock speedo-tach readings aren't 100% accurate, but 1st and second are above 2500rpm, 3rd is right at 2500rpm, and 4th and 5th are below 2500 rpm. Also, as I remember from when it was stock, the shift points would decrease from 1st to 2nd and from 4th to 5th, something like this: 2700rpm (1st), 2600rpm (2nd), 2500rpm (3rd), 2400rpm (4th), 2300rpm (5th). Bear in mind, this was just a mental note I took from when my Jeep was in stock condition.

An interesting point I want to say though...After I had my Jeep regeared with 5.13's with 35's, it really is a ton of gear for the size tires and the transmission. With that, I can now tell that the engine has a certain point where it likes to be revved at, and that is 2500rpm or below. Above this point, I can really feel the transmission/engine/stick start to vibrate much more and below that, it feels really smooth. It might be the powerband? Therefore, I usually try to go no more than 60mph on the highway now, until I move up to 37's, as that is just about right where I hit 2500rpm. Edit: bear in mind this is with the speedo corrected.

 

Smoke coming out of clutch openings = burning clutch

 

Same here, guess that is why I am over 20 a gallon.

 

I shift at 3k, through all gears. It seems to be the perfect spot for smooth gear transition and decent mpg.

for me it depends on traffic conditions and traffic needs, sometimes 2000 maybe 2500 and other times maybe 4000 if i really need to get going.
