Question about 1996 GMC Suburban

96 Gmc Suburban 4x4

Hi. I am hoping you can give me some pointers. I recently experienced a leak in my transmission on a 4x4 model. I had the transmission replaced but I have not been able to confirm that it has been fixed as after the transmission was installed the truck was making a noise that appears to be a clacking noise coming from the motor. The transmission trouble developed while on main interstate in the middle of traffic. While trying to get out of traffic, the RPM's went really high.(red Line) The transmission specialist who is not really familar with motors suggested it could be the crank and the pan would have to be dropped on the motor. Prior to this transmission issue the truck was quiet running. Are we headed in the correct direction thinking it could be the crank, which I have no idea what this is or what it does. Can someone please give me some input. Any and all assistance is appreciated

It could be a few things . The 4x4 is vacuum opperated it could be the actuator under the battery tray or a vacuum leak someware between the transmission switch and the actuator or a faulty transmission switch or ever a simple adjustment to the shift mechinisem depending on if you have the manual or electroinc shift set up or an adjustment at the front carrier cable . Its kind of hard to say with out seeing it but its vary likely one of these things good luck with it . If you have more questions fell free to ask

unfortunately what it sounds like is the transfer case like you suspect. inside are bearings and gears and a chain what happens is the chain will stretch and cause this problem it will actually jump the teeth on the gears, you will need to have the chain replaced in the transfer case. sorry to have to tell you this but i hope it helps.

My '96 Suburban 1500 4x4 won't shift into 4 wheel drive. When I push the button for 4 Hi the light just flashes and stays in 2 wheel drive.


the electric shift motor on transfer case is bad, replace and it will work great. if your at all mechanically inclined you can do this very easy. before unbolting motor disconnect battery to reset computer install part, should only take you 15 min maybe then hook up battery and you will have 4 wheel drive again. good luck
