I just recently started having an issue with the transmission. I have the manual transmission. After I shift and take my foot off the clutch and give it gas my rpm will increase to 35,40 before it acts like it drops into gears. It will also do it if I give it gas quickly to pass a car. I especially notice it when driving up any sort of incline. Any suggestions what the issue is and where to start? Thanks!

That is when you really need a shop mechanic works.
Very risky to DYI anything related to transmission.

I don't mind doing the work. I love working in the jeep. Last year I replaced my wife's clutch and master cylinder. I just don't want to to replacing things that don't need it right now.
Sounds like your clutch is slipping, if that's the case you should see some smoke and smell some clutch disc getting hot.

For a manual trans (clutch does not slips while the jeep is running) gear does slips - if it slips out of gear it goes to neutral not to the lower gear.
Clutches can slip when they are bad when in gear, maybe the pressure plate has a problem with broken springs.

Take it to a shop and have them look at it and give you a estimate then when you see the estimate just say you'll have to wait a while since it's so much because you haven't worked for a while.

A basic test for a clutch is to put it in second gear, rev it like normal take off, but keep the brake on (or parking brake) when you slowly release the clutch.
If it don't stall right a way, you got problems.
Back in the old days, my dad replaced a clutch in a truck by himself, lying on his back in a field. But if one has the money, paying some one that has a lift and experience would be a lot easier.

Tried this and it didn't stall. If it hadn't been in park and I kept going it probably would have dropped into second gear.
Why are you saying your Manual Trans has a PARK? Also a Manual Trans will not shift into another gear unless you manually shift it so why are you saying it would have dropped into 2nd gear? From the way your talking about it it's a automatic trans.
Sorry... the parking brake was engaged. And I manually had it in second gear. I have a 6 speed manual transmission. If I hadn't had the parking brake on it would have gone into second gear and not stalled.

I'm having this same issue. I just downloaded the jscan app and I have a Bluetooth OBD scanner on the way. Is there anything I can find out with these tools before taking my Jeep to get a new clutch?

The clutch is purely mechanical. Even with the over computerized modern jeep I don't think they have found a way to interfere with it's function.
Besides the clutch kit, you have to be sure the seals on the engine and transmission are perfect, if there is any question, now is the time to replace them. Dry clutches do not respond well to any type of fluid, and the main cost of replacing the clutch is dropping and installing the drive train. I wouldn't mess with the seals if they look okay, but others may disagree. If a true professional does the job, just go by their recommendation.
