you've got a 42RLE. swapping it for a manual will be a HUGE PITA. trust me on this one....I looked into quite deeply and just decided to regear and live with the crappy 42RLE.
The TCM (Transmission Control Module) is heavily integrated into the PCM (Powertrain Control Module). This means the manual and auto use different PCM's & there are some wiring harness differences.
You'd also need to change the starter, crank position sensor and you need to install a pilot bearing on the crankshaft. There is no direct connection between the engine & the auto on a 42RLE, so no pilot bearing is installed. One of the conversions I've been watching over on JF, the guy used a Hesco front mounted crank position sensor. The CPS's are different between the NV3550 and the 42RLE.
And of course you need the TJ manual pedals (brake, clutch), and the clutch sensor. Then you'll need all the slave cylinder stuff, lines, etc.
And of course the transmission. you may run into issues with output shaft of the tranny and the input shaft on the t-case. The manual's used a long input shaft on the t-case, and the auto's used a short input shaft...but all Rubicon's used short, so it might not be that big of a deal.
