Hey guys,

Having a problem with my 2006 Jeep TJ with a 6-speed manual transmission.

After driving my jeep for 20 to 30 minutes it will randomly start to "slip". This slip happens in different gears, does not last very long, and is usually while going up a hill.

My first thought was maybe the clutch disc was worn out and causing the slipping issue. I replaced the clutch with a LUX clutch and the problem is still present. My next thought was maybe the transfer case chain, but after thinking about it, the transfer case chain should not play a role in this issue while in 2wd?

Anyone have any thoughts and what to try next? let me know if you need more information.
 
There are a few potential causes that could explain the slipping issue that you are experiencing in your 2006 Jeep TJ.

1. Transmission Fluid - One possibility is that the transmission fluid is low or in need of a change. This can cause slipping due to insufficient lubrication or buildup of contaminants in the fluid that can interfere with proper gear engagement.

2. Clutch Hydraulic System - Another possible culprit could be the clutch hydraulic system, including the master cylinder, slave cylinder, and associated lines. If there is air in the system or a leak, this can cause inconsistent clutch engagement, which could manifest as slipping in different gears.

3. Clutch Components - While you've already replaced the clutch disc, there are other components that could be contributing to the slipping issue. This includes the pressure plate, throwout bearing, and flywheel. If any of these parts are worn or damaged, it could interfere with proper clutch engagement.

4. Transmission Synchronizers - The third gear synchronizer in the NV3550 manual transmission used in the 2006 Jeep TJ is known to be a weak point. If the synchronizers are worn, it could cause issues with gear engagement, especially when the transmission is warm.

Given that you've already replaced the clutch and ruled out the transfer case chain as the issue, it may be worth looking into these other potential causes. Checking the transmission fluid level and condition would be a good starting point, followed by a thorough inspection of the clutch hydraulic system and clutch components. If those checks don't turn up anything, then inspecting the transmission synchronizers may be necessary.
