No c7 wasn’t engaged. Good thinking I will do a main test with c7 engaged. I haven’t found a breakdown with c7 valve body to the transfer case to see if a gasket is used. I wouldn’t think they would let cast iron sit directly on aluminium ? Another thought, with mode on the transmission...

Ok main pressure is between 235 and 250 at idle. Can anyone tell me if there is supposed to be a gasket between c7 valve body and the transfer case?? Seems like there should be but I don’t have one there. Did a leak down,100% leak down. From under the valve body?? Or valve body is...

I didn’t check main pressure, the transmission functions really good. No shift flare ,no slipping and no codes. You are probably correct on 1st gear . I’m going to do a leak down on c7. I will check the main pressure just to be sure. I haven’t pulled the 2 filters just the screen on the...

Ok I had time to test pressure for the c7 clutch pack. Idle it’s only 65/70 psi. It’s is the same in 1st as it is in mode. So looks like the tcm is functioning fine. Anyone have a good source for transmission/ transfer case parts. Allison is crazy expensive! Fluid volume seems very good...

I like it! Two thumbs up. We have upgraded the split collars to 1/2” thick with a 1/4”x20 Allen bolt. All new sets will ship with the updated split collar. I do like your idea, I’m going to see what it Might cost to incorporate it down the road. Thanks for posting. Might be able to...

Thanks!

Yes it does.

Look for a loose connection behind the fuse panel. Big wires work loose over time.

I jack the one wheel up put it in mode and one wheel spins (rear). Put it in first and it will drive off the jack no problem. I know it’s a little different?? I will test pressure on c7 to verify what I think is happening.

Hi everyone I’m again working on my Lmtv. The problem of the day is the transfer case doesn’t engage 50/50 when mode is selected. However it does when I select 1st gear. I checked the scavenging screen, looked real good. A few bits of plastics or gasket material. I am going to check c7...

That’s the reason all split collars are shipped with the Allen’s installed. To make sure there isn’t a problem with the threads. The false start is a problem. I will gladly send you another split lock. When the new lock rings are available, this problem should be gone. ( Bigger allen and...

I don’t like that fix, I will be glad to send you another lock ring. The problem with the threads is that they are formed threads not cut. That makes them stronger and tighter more consistent. However they have a false start sometimes. If you engage the false start and continue it will...

I would think all you would need to do to make the pac break more effective is to increase RPM. Like downshift, 2000 rpm with Eco hubs is the same as 2000 rpm with reduction. For the same road speed you will be in a different transmission gear. Flaps up or down ??

I don’t think Eco Hubs have any effect on the pack break at all. It’s the RPM the engine is operating at when the pack break is applied/used. More RPM more breaking power. Down shift the transmission to increase breaking effectiveness. Am I missing something?
