    Can Transfer Case slip into neutral?

    Is the VSS the only thing I need to be logging? If I'm gonna take off on a 200 mile trip just to try and get it to do it, I don't want to skip logging something I should.

    Can Transfer Case slip into neutral?

    Well, I took the truck out this afternoon and drove about 90 miles on the highway and couldn't get it to replicate the problem. Of course. Never does it when I want it to, but does it all the time when I'm not trying to log it. So, where should I go from here? I don't particularly want to rip...

    Can Transfer Case slip into neutral?

    Okay. Tomorrow I will try and log it to see if I can get the problem to show up and see if the speed sensor does anything to confirm the transfer case issue. Is there anything else I should log just in case?

    Can Transfer Case slip into neutral?

    When it happens, it feels like it drops out and then catches hard and continues on driving like normal. I'd be glad to log it, but what should I log? And how do I post logs? I've tried before, but it won't let .efi files be uploaded on here. Mike - being that you are the expert, I trust...

    Can Transfer Case slip into neutral?

    *Edit for clarity* - Truck is a 2006 LBZ with the Allison and has the 263 with the push button shift transfer case.* I'm having an issue with the truck that I can't figure out. Sometimes, mostly while cruising on the highway for long distances, it will "slip" like it is going into neutral and...

    Help: Transmission, fuel, electrical problem?

    I tried driving around town today to get a video, but I couldn't get the truck to do it. Anyone know how I can upload the efi logs? I still haven't figured that out either. I did find a guy locally who has some transfer cases. Remans with about 80k on them. Wants $500 each. Think that would be...

    Help: Transmission, fuel, electrical problem?

    Here are the only pictures I took of the transfer case. I know it isn't likely to spot anything in such a vague picture, but I figure it can't hurt to try. Also, those shavings were in the pump when I opened it up. Not sure if that is a normal amount or not for a case with 230k on it.

    Help: Transmission, fuel, electrical problem?

    I can try making a video tomorrow. I tried while cruising on the highway, but I'm just too shaky. I'll attach the two logs. Forgive my ignorance as I have no idea if I logged the right things. Other than checking the DSP switch voltage and injector balance rates on trucks, I've never done...

    Cruise control

    On my 08, the ABS light was on and the cruise control still worked. Though at one point it did quit on me and it was the brake switch that had gone out. Sometimes if I pulled up on the brake pedal with my toes, I could get it to set. Can't say if that would or even could be an issue for you...

    Help: Transmission, fuel, electrical problem?

    I want to apologize in advance for this being so long. I want to be thorough so that maybe someone can help me. I've had it posted for a few days on the other forum and haven't got much response, so hoping since this place is a bit more technical, I may get some more opinions. Here is the...

    PPE Duramaximizer problems Help!!!

    I just finished installing my duramaximizer about 10 mins ago. I tried to start the truck, and once it started it was loping really bad and threw the SES light. I have no idea what to do, its pretty hard to mess up the install on the duramaximizer. But obviously this is the problem because the...

    I need help

    Hey y'all I could use some insight. My mpgs have dropped significantly in the last month.from about 17 to 13. All right after I got my new injectors from the dealer. I really expected my mpg to go up after the injectors. Not down 4. I replaced the fuel filter at the same time as the injectors...

    Thought I'd Share This

    I have an 02 LB7. I bought the truck used about 2 years ago and bought an aftermarket warranty from Fidelity. About 8 months ago my truck started smoking, got sluggish, etc. I took it to the dealer assuming injectors were gone. Twice. Both times they said I was within spec. But about a week ago...

    injectors? or something else?

My 02 smokes all the time. at idle, low boost and all the way at the top. I have nothing a k&n. no tuner or exhaust or anything. and when you jump on the throttle at...
