Question about 1994 GMC Suburban
My 94 GMC suburban NP241C transfer case slips out of gear and goes into neutral. I've changed oil and replaced the switch but still have hard time engaging or staying in 2 or 4 wheel drive.I've checked my linkage. It'll slip out of gear whether i'm giving it gas or evan at idle. The only time it does engage every time is in reverse and only in 4 low but will still slip out after a while. If I were to buy a rebuild kit would that solve my problem or would I still require more parts aside from what comes in a rebuild kit? The transfer case is a stick shift and not a push button. Thank You!

91-97 Land Cruisers had a factory option for front and rear locking differentials. This is a seperate switch and is usually located to the left of US model Land Cruisers. The center dash button locks your transfer case differential changing your Land Cruiser from all wheel drive to four wheel drive depending if you have ABS or not this button either says ECT or Center Dif Lock. If you do not have the Front/Rear locking differential option then your Land Cruiser has open Front and Rear. Hope this answers your question.

Problem sounds like an internal pressure problem not a cable. If you are able to shift into all gears using the shifter, the linkage is being moved properly. It cannot "come out of gear" by way of the shifter.
In reality, if you were able to manually put the shift lever on the transmission into any particular gear without any shift cable at all attached, it would stay in that selected position forever till you got under there and moved it again. Depending upon what transmission you are using you may have a throttle cable running between the trans and throttle lever on the throttle body...this may have something to do with your problem but would also affect shift points. Any electronic shift controls are also suspect at this point. have it checked by a competent shop. In not being there myself, I can only offer my thoughts on what I would test going into the problem...after testing a better evaluation can be made. Good luck...Hope it's something simple.

I had this exact problem on my 2005 5.3L Suburban... It would shift into 1 and 2 and reverse, but not 3 and 4.
I took it into a transmission shop, and he said the 3-4 shift solenoid was burned up. Wanted 1500 to fix it. Far from home, so I have to pay it.
