Gm 6.0 Trans/transfer case help.
It's probably a noob question but I know jack about gm stuff. My situation is this:
I've got a 97 TJ and plan on swapping in a gm 6.0 in the near future. My question is what suggestions do y'all have about transfer case. Keep in mind it has to be driver drop to keep the axles I've got. And it's not budget friendly to go one ton yet as I've regeared, detroits fr and rr, chromoly fr and rr. So for now my 44's will have to stay. The obvious is atlas. But that will seriously delay the swap a while til I can afford it. It'll happen one day just not today. Lol. So what transfer case can I use that readily available in a driver drop and not a POS? Also, the plan is a 700r4 because I want overdrive and to help the budget. Is that the way to go or would you run a 4l80? I appreciate any info you can offer. |

700R4 and 4l80E are the same but different. One is the electronic shift version on the other. Both are expensive to rebuild but great transmissions.
I would run what ever is cheap to bolt behind one the transmission you use. Also keep in mind that 6.0L is going to be a lot of stress on those 44's. Adding that weight to the front end and HP. You will break. |

i run an nv4500 behind my 6.0 and love it because you still have the low crawl gear and you have the highway gear if youre planning on daily driving. just a thought and option. transfer case i agree with awesome bill on the 241 until you can afford an atlas! and these guys know more about the dana 300 than i do but it might be an option to.

Wouldn't consider the 300, takes $$$$ to make it hold up, a well as a flip kit to work for driver side drop like he needs.

I really. Want to stick with an auto. The main reason for a 700r4 over a 4180e is just mainly cost. I figured I could pick one up cheaper. That might not be the case that's where I could use more opinions.
What vehicle would I source a 241 from and do they make a slip yoke eliminator for it if it needs one? |

Starting in about 1987, the New Process 231/241 series transfer case became standard in Jeep, Dodge, and Chevrolet applications. These transfer cases are part time 4WD (Shift positions 4HI - 2HI - N - 4L). They have a relatively thin aluminum housing. They are 1:1 direct drive in high range, and use planetary reduction gears for low range with a ratio of 2.72:1 They use chain drive for the front output. The NP241 was typically used in V8 applications.
Exact identification: These New Process cases have a circular plate, about 2" in dia., on the rear of the case, in the center. Full identification info for the case is on this plate Bolt Pattern: Jeep, Dodge and Chevy versions all use a 6 bolt circular bolt pattern. This pattern is NOT symmetrical and will only bolt up one way. You can typically bolt a Jeep unit to a Dodge transmission and vice versa, however Chevrolet units are NOT cross compatible: While GM uses the same 6 bolt patter, they have it rotate approximately 90 degrees from that used by jeep dodge. In all of these 6 bolt applications the Klune-V Extreme Underdrive will bolt up to these transfer cases directly with adapters necessary. Some may require a spacer. Slip-Yoke Eliminator All of these units we have seen have been equipped with a slip-yoke rear output. Slip-Yoke Eliminator kits are available for most of these transfer cases Jeep / Dodge units: All of these cases have a left hand drop (front drive shaft on driver's side). Input Spline: most applications use a 23 spline female input shaft. All Dodge Cummins or V10 NV4500HD application 241s use a 29 spline. Also 99-up NV4500 standard duty gas apps GM New Process 241 Transfer Case In 1988, GM began using the NP241 transfer cases. Most of these units will be right hand drop, but Chevy also used a few left hand drop applications. The Chevy NP241 is supplied with a 27 spline female input or a 32 spline female input. With a T350, 4L60E or 700R4 tranny, it will be 27 spline. With a T400 or 4L80E trans or 5 speed, it will be 32 spline.

A lot of your newer Chevy IFS trucks came with driver drop 241's and if you need you can swap inputs in it to match the trans you will be using. I personally would sleep better at night knowing I had a 4L80E bolted to a 6.0 instead of a 700r4 but that's me. Seems like they took a little work to hold up and a 4L80E won't need a thing. And yes they do make slip yoke eliminators for 241's.

And I know the 44's won't be happy under a 6.0, but one step at a time. I drive fairly cautious offroad. I think I can make them last until I can build tons. Which I really want. Just have a huge chunk of change in the 44's.

4l80 is a beast! Long too, 700 or 4l60 would probably be a nicer install...

This is a jeep guys. He's not pulling any trailers.
Also a 700r4 has a nice first gear compared to. What size tires are you going to run?

I've got 37's right now. Would like to ultimately be around 40" but prob after axles. I'm geared steep right now at 5.89 due to my crappy 4cyl.

Also once I go to tons I might stretch the wheelbase a bit more. But for now it's only stretched about an inch in the rear. Mainly building it as a driver/wheeler. Would like it to stay street legal and be a valid means of transportation. Mainly a toy but still transportation nonetheless. I drive my one ton daily and the jeep maybe once a week at best.

A 700r4 would love that setup.

So it's sounding like a 700r and a 241 is the way to go...

And that's extremely easy to find. For what its worth, 90k5 is an excellent example of a good use of a 700r4. You're light and well geared. It could potentially fare pretty well, even stock.

That's something I might be interested in. I've got a 4.8 I planned on putting in but I think if I'm going to swap I might as well go a little bigger. I've kinda got a deal working on a 6.0 with a buddy. I should know this week if it goes through. I doubt it will so I may be real interested in yours.

I have done this whole swap in one of my YJ projects. I did the 6.0, 4L80e, Atlas 5.0. Dana60/14bolt. Back half YJ.
Buy the 5.3/ 4L60 that 91explorer has. This would be your cheapest route. Then get an NP241 to bolt to it. Keep your tires under 38" and the D44's will last a while. I have built a half/dozen rigs with v-8's. I love the sound of a v-8. I now a 4.0 TJ. I plan to leave the 4.0 as long as it runs. I am running hi-pinion Currie 9's with 4:88's and detroit lockers. It has enough power to go up anything I want to go up. Good luck on the swap.

Thanks for the info Don. If I had the 4.0 I wouldn't even be thinking about a swap. But this puny 4 cyl is getting on my nerves in a quick hurry.

OH yeah. The 4cyl. needs to go.
Just a suggestion. Cheaper, easier. Find a cherokee with the AW4 and 4.0 combo. It would all bolt up with minor wiring changes.
