Ok, I had a 242 swapped in for my stock 249. I have since had issues with the linkage and the selector hitting all the gears correctly. The shop used the original linkage, and I have played with it and just can not get it to work. Growing extremely frustrated!!!

Another issue:
My VIC is not reading correctly even though I pulled it out and swapped the black and red plugs per the instructions I found on one of these forums. When I shift through what gears I can, it seems that the VIC is reading opposite what it should...

Any suggestions would be greatly appreciated!!

When I am in 2H, mine says full time. When I move the selector I hit 2 more gears which the VIC reads as part time, and I have N. So I am hitting a total of 3 gears and neutral when I beleive there should be 4 gears (2H, 4H, N, 4PT, 4L).

You now to get 4L you have to be in neutral.

Mine reads part time whenever I'm in 4L. But it didn't say any thing when in 2H.

Yes, I know that! Does it change anything, no. I am completely missing 4L on the selector...

I beleive mine was out of a 96 I6. At least that is what the shop was toldwhen they got it.

If your VIC is reading wrong you either didnt change the plugs right or your switch on the t-case is bad. The linkage does take a little tinkering. When you do the swap you CAN NOT use the tab from the 249 on the 242. You must use the shfter tab that goes with the 242 of you will never get it adjusted right. By tab i mean the metal bracket thats bolted to the side of the 242 that the shifter rod connects to.

Thanks for the info PlatinumNiner.
As far as I know, the switches were not changed out. As for the plugs, I followed the directions I found here. I unplugged the RED and plugged in the BLACK. Before doing this, I got a "Service 4WD Switch" warning on the VIC. Now, it will read either Full, Part, or Neutral... It just seems backwards from what it should be. The 242 sequence, from what I have read, goes:
2H-4PT-4FT-N-4L

When I attempt to run through the gears, my VIC reads:
FT-PT-N-L

The problem is I beleive because of my linkage. I am not hitting "4L". I shift into drive and it is not in gear at all. When my lever is all the way forward (2H) I am not sure it is in or not, also becuse of the linkage. I crawled underneath, and it seems that I amnot able to go all the way forward because the linkage from the TC to the pivot point on the trans is being held up by the rod that goes from the pivot point to the selector linkage. Almost as if my linkage needs to be shortened by 1/4" to 1/2".

I found a shorter linkage off a ZJ and was told it was off a 242. The shop told me that they used the original linkage from my 249, so I am curious if the shorter linkage will work.

You speak of a "TAB"... If I am correct, when I look at the shorter linkage, one end has a gold colored bracket that attaches to the TC. Wuld that be the tab you are speaking of??

The linkage has no part of your vic reading it in the switch or the vic. You can un hook the tc and move the selector your self and see its still going to read rong.

Sounds like your linkage needs to be adjusted (which is easy) AND/OR your 4WD switch may be bad. The linkage is easy to adjust. There is a bolt on the round rod that you loosen. THe linkage should be free to pivot. Get a friend to manipulate the lever while you adjust it. Keep tinkering until you get it.

If you still get the same malfunctioning readout after you are able to get into all ranges, you might try replacing the switch.

As an aside, there ARE different pieces for the linkage on the 242 than the 249 besides the selector lever on the case. I'm guessing there are different length rods and shifter gates and whatnot. Most people don't bother getting them because you CAN get your 249 linkage to work. As a last resort, you could buy the 242 pieces and give them a shot. But I just think your linkage needs adjusted for now.

Yeah, the TC drop is messing up your linkage geometry. You either need to fab a bracket to lower the linkage (popular on cheaper TJ lifts) or take the TC drop out. With an SYE, you SHOULD be okay without it. However, you may get unacceptable vibes from the FRONT DS if you take it out. Hard to say.

But, trying it is free. Take the TC drop out and see if you have any vibes. If you don't, you're golden. If you do, put it back in and then expend the effort to correct the linkage geometry with a drop bracket.
