Select trac vs Command trac

A foundational question. I'm wondering if 95 may have been a transitional year in Transfer cases. I have command trac but my owners manual lists both. Did the earlier years just have select and the later models have just command or was there usually both available.
It seems the transmission was the same in my 95 for both transfer cases. But it sounds like the select trac is the most common.

Re: Select trac vs Command trac

The 242 was almost always an option. I have one in my 89. They list both so that they do not have to print two books. They put every option in the manual.
There is only one auto trans from 87-01 the AW4.

Re: Select trac vs Command trac

both were available for many years

search NP231 and NP242 and you can read about the differences and pros/cons of each, as well as how to make them stronger/better for your applicaion.

Thanks that helps me understand a lot. So any TCU I get from 87 to 01 will work?

That's the same production range as the NP231 and 242 were used; both t-cases were available throughout that entire range.

How did we go from transfer cases to TCU's? What is the actual question because these two are unrelated. Oh and I don't think the TCU's will swap over through the years as they interface with the comp differntly. The AW4 though I believe will work with the AW4 XJ TCU's regardless of year.

Re: Select trac vs Command trac

Sorry for taking a left step. I started with a TCU question in another topic and realized I wasn't sure on the basics. Now I understand about the transmission and the T/C I will ask my other question better.
thanks

No in 95-96 the TCU was built into the ECU, some 95ís had a separate TCU and some didnít

Are you sure that the TCU was built into the ECU in 95 and 96? Cause I know older models (93-? 94-?)had it separate and 97+ have them separate as well.

I don't know for sure, I thought that they started in 95 or 96 to build them in.

Hmm, that'd be weird cause in 97 they separated them again.
