What is the difference between transfer case NV231 & transfer case NV242 ??

tjkj2002 · **Posted:** Tue Mar 10, 2009 9:12 pm

The 231 can not be in part time or 4low on high traction surfaces,that includes wet pavement.

The 242 has a center diff in it that allows the F/R driveshafts to spin at different speeds making the "full time" option usable on high traction surfaces but when in part time and 4low it locks the center diff just like the 231.

Oh and the 231 is a direct shift t-case,the 242 is not,it uses check balls to shift the t-case and is prone to failure.

I love my Select Trac NV242. I use full time when it snows, rains, on mt. roads, fire roads, etc. Works great and I don't have to worry about hitting high traction areas. For my uses it is the ideal transfercase, which is why we bought one with the Select Trac.

Ditto..........and despite it being "not as strong" as the 231, I have not broke it......yet anyway..... and I do use it a lot.

231..or Command Trac.

Everytime I use it I hope it doesn't explode, not knowing if the surface I drive on is slippery enough....or not...

I only use mine after a I feel slip on snow or ice...otherwise I don't need it...although I did use it more when I still had the OEM Goodforayears... :evil:

I find it surprising that the 231 transfer case is the same model used in most TJ's & YJ's.

I wonder if it's possible to put a twin stick 300 transfer case in a Libby :roll:

Believes the use of almost any T-Case is possible with the right amount of money.

Yep,well almost,needs to have the right spline count and depth,and of course mounting surface but adapter brakets can be had from Advance Adapters.Speaking of Advance Adapters this beauty is replacing my 231.

There is also the 241HD that comes with the manual transmissions, or is this poll only open to automatic transmission owners?

InCommando · **Posted:** Thu Mar 12, 2009 2:38 am

Someone will chime in to tell you there is no such thing as the 241J- it is a 231HD. :lol:

Just as a 400sbc is a 305HD :shock:

Actually, the 6 spds use the 241J, which is the Command Trac HD option to seperate it from the normal Command Trac (231J), but the case is not the 241HD. The only 241 HD that I know of is the Dodge 241 D HD. Or to those I referenced above, it is the 231dodge heavydutyheavyduty..... :lol:

The 241OR from the rubi is arguably a hd version of the 241.

Ooops, I did not want to start that thread again. :shock:

I was being warm and lazy when I guessed about the transfer case being the 241HD. It was way too cold this evening to climb under the Jeep and look. :lol:

Yeah that is true,but most do not no the difference between "NV" and "NP" even though they are the same company now so I let go the fact the mislabeled the 231,the NV241 gets mislabeled the most since that is the RockTrac t-case in the Rubicons only(goes by many names).The correct name for the command trac in the KJ is NP231,not NV231.

New Venture, New Process, et al has a seriously convulted lineage.

Is it possible to swap out the command Trac tf case for the select Trac with center diff? I have a 2005 6spd manual sport 2.8CRD

ATXKJ · **Posted:** Sun Dec 20, 2009 9:56 am

I believe it's mechanically do-able - i.e. it bolts up
however Jeep didn't do that combination
there's a lot of concern about the stress loading on the transfer case as a result of the manual transmission.
That said - Sir Sam was working on doing that

haven't see any details for a while
