Maybe I miss understood your request, but I do not recall ANY vacuum lines directly connected to the transmission or transfer case.

Vacuum is used by the ECM to determine load, so I included those here.

If you need something else please let me know ASAP

Where do the vaccum lines go into the transfer case on a 2002 RAM 3500? I need a diagram of the vaccum lines into the transfer case.

Vacuum lines do not actually go into the transfer case, they go to the 4x4 actuator and there is a vent hose at the top...that is about it.

Removal of 1990 gmc serra 4x4 transmission

with the assumption its an automatic the following applies(if a manual youll need to remove the slave cylinder from the transmission, its located above the starter) 1.Disconnect the battery and place truck on jackstands if needed for clearance and remove the starter 2. Remove front and rear drivelines as well as speedo sender and and shift linkage (remove shift lever if manual and transfer case shift linkage if not push button, you should be able to just seperate the linkage from the ****** and transfer case and leave the linkage dangling) and any other electrical connections to ****** and transfer case (such as push button transfer case, and electronic automatic trannies) make sure to scribe a line or mark the drivelines in relationship to the yokes so they get installed in the same position for balance 3. Remove transfer case, this will take some of the weight off and make moving the ****** around much easier on you 4. Beggining with the top bellhousing bolt remove all but the bottom two bellhousing bolts (save those for later, one on each side) 5. youre going to need a helper for the next part unless you have a transmission cradle for your floor jack support the transmission with a floor jack remove the crossmember bolts from the frame or completely remove the crossmember from the equation,, either way works 6. remove the two bottom bellhousing bolts from earlier, the transmission is now free, you will have to wiggle it around some and **** it as sometimes the splines on the torque converter bind up, sometimes in low clearance applications you need to support the motor with hoist, remove the motor mounts and drop the motor slightly to get a better angle. sometimes the ****** will pop right off and sometimes you have to fight it a bit but thats the way it goes, just remember the ****** is heavy so be carefull if not useing a ****** cradle! hope this helps out, good luck. also i recomend buy a chilton service manual for any do it yourselfers, its only about 15 bucks and covers alot of stuff, such as removing the ******.

4 wheel drive will not engage on my 1989 gmc sierra 2500?

actually that first soultion is wrong it is correct on smaller pickups but on the full size pick ups they use a differnet sytem
there a electric actuator on front axle
there be two elctrical plugs on front axle u want the bigger of the two other one is just to turn the 4 wheel drive light on
un plug actuator then remove actuator after it removed plug it back in but leave it out of axle turn key on and shift down to 4 wheel drive the actuator should move out if it dont that your problem if i does move this isnt your problem it either the tranfer case or in front axle
