Silly noob question (manual)

I bought my first jeep the other day (07 JKR) and I decided to get a manual transmission (1st one). So question time. I keep hearing about a shift light indicator, but have not found one. Can anyone confirm this? Also, when I shift, the jeep jerks if I don't let the clutch out slowly. Is this normal? I only thought I had to go that going into first.

I'm sure I'll have some new beginner questions (especially when I try offroading - god help me), but I appreciate any advice whether it's opinion or fact.

Rough shifting is something that is hard to coach without riding along. But the most common reason is dropping off the throttle too much. It takes practice but what you want to do is come off the throttle only enough to match RPM - that is if you are at 2500RPM when you shift and the the next gear will put you at 1800 - then you want the engine at 1800 (not 800 idle) as you let out the clutch. One way to practice is to shallow clutch - that is just before you upshift apply a light pressure to the stick - when you clutch do not go all the way to the floor with the clutch - just go down far enough to feel the unload point (plus a tad) - you will feel the unload point (shifter will go) as torque is removed - at THAT point lightly lift the throttle and it will RPM match right into the next gear. Downshifting you don't even have to lift the throttle - the unload will speed the engine up to match - if downshifting with NO throttle (engine braking decel) just "burp" the throttle to match!

Of course I have not driven a stick with the electronic throttle so it may be defeating this. In that case the only way to smooth is to just practice shifting faster (without using more force). I was brutal until I learned to shift without a clutch - but that is brutal on the syncros until you get it right.

The wagon should, of course, be as light as possible, but strength should not be sacrificed to lightness, for on any but the regularly traveled roads, the wagon will get many a hard knock...

That is a very good explanation. I think I am letting my RPM's drop too much before I actually engage the next gear. I'll give that a try tonight. Thank you for giving me a well thought out response instead of just making fun of me.

When I switched back to a manual I was shifting poorly because I thought about it too much.

Go for a driver around an area with a lot of stops and turns. Try things out. Try quick, slow, giving abit of gas, etc see what feels right. Then stop thinking about shifting. After awhile it becomes second nature.

I find Jeep transmissions are ruff but also forgiving. I'm still working on down shifting on this JK.. I've only owned it 2 months and it feels much different From my TJ.

No problem - been there so I understand and after teaching all three of my kids to drive, coaching two rookies in stock cars (one gave me his rookie of the year trophy) as well as several veterans - I have learned to approach it with patience. I am now coaching my 70 year old mother on driving her motorhome - that has tapped that patience to no end.

If you still have problems with a rough shift - just take it to the dealer and complain about the loose nut on the shifter...

Ive been driving my manual 2011 JK for 3-4 months.. In the past I've driven many manual exotics. Maserati, Z06 Vette, CTS-V, etc. no I'm not rich I detail cars... But when I drove those cars they are all very smooth if i want a smooth ride i generally shift the wrangler around 2000rpm not much get up and go and i still bounce around a bit. so its just bouncy lol
