I can understand that, my thoughts were that the clutches were shot. It has 140k+ on the original trans. If it's purely mechanical, then what is with the TCU under my drivers seat?

I'll have to get my hands on an inch/lbs torque wrench and try that this weekend, who knows maybe it is that simple and my headaches will go away.

I do not know for sure, sorry. I can't help you any more.

Sorry it took so long to get back on this one, wife's car took precedence. Did the band adjustment and adjusted the TV cable and now the 1-2 shift is much smoother. Still a little hesitation but I am sure that's from a year of driving it the way it had been. Thanks for the information JBTJ!

The 42 rh and the 42 re are different. The 42 re is electric lockup and requires a tcm. The 42 rh is all mechanical and should in theory, operate like the 32 rh + another gear. The 42 rh should slide right in behind the 4.0 but the bolt pattern is different on the output side where the transfer case mates up. Someone correct me if I missed anything.

The 46RH is 13" longer than the TF999. That, my friend is a big deal on a short wheel base Jeep. The 46RH is what I am currently running in my Jeep with a 5.2 swap. I pushed the engine as close to the radiator as possible and stretched the wheel base to make it work. I am currently shopping for an old 727 so I can get some more drive shaft length. My YJ drive shaft is about 16" so I'm thinking a 3" drive shaft may be an issue.

The tc bolt pattern is not an issue. I am running a NP231 behind the 46RH. I did have to change the input shaft in the tc though.
