    Tcm??

    Unfortunatly Im not going to have a scan tool to use when I try swapping them. Just gonna do it in my spare time at work with a company truck. An observation I have made in all of my testing/diagnosing is that it makes no difference whatsoever if the TCM is plugged in or not when I...

    Tcm??

    I have a working TCM from a 2003. Can I just try it without having to reprogram or anything?? What I actually want to do is try my TCM in the 03 to see if it has the same symptoms or not.

    It's code u0101. The TCM won't communicate

    Tcm??

    If I were to try another TCM would any reprogramming need to be done as long as it cam from another 4x4 5spd? I have had the harness out and unwrapped from TCM plugs to under hood fuse block and also from there back to trans to inspect it. Couldn't visually see damage. I havent checked...

    Tcm??

    Still trying to diagnose my u0101. So far at the TCM connector I have confirmed 12v constant, 12v ignition source and both grounds. The serial data wire is good to the DLC, the CAN LO and CAN HI wires are good to the ECM. All my other ground connections are clean and solid. Tow haul mode and OD...

    U0101

    Im at that point now. I tore the entire harness out and went through it. I also tried an ignition switch. Best price I have found for a new TCM here is just shy of $1000 and with no guarantee that it will fix the problem and can't be returned Im a little bit gun shy. Can a TCM from any 5...

    U0101

    Starting to feel like an annoyance being the only one posting but I'm pulling my hair out here. Anyways.. Is there any chance all of this could be due to a faulty ignition switch?

    U0101

    When I disconnect/reconnect the batteries there is alot of arcing. Something is pulling a draw pretty hard somewhere but I cant figure out where. Should there be any draw at all in this system with nothing on and all doors closed? Is there a procedure to find an electrical draw? Load tested both...

    U0101

    Could be but it wouldnt make sense that it was all working fine and then suddenly all this just started happening without taking anything apart. It did happen right around the same time I put all new front bulbs in and installed the inner fenders. I cant find any signs in the are though. I...

    U0101

    while parked not running but with the ignition on the rear driver side door is making a bunch of clicking noises like the window motor is trying to go up or down and I can't make it go up or down with the front or rear button. Also just moved it and the turbo vanes started cycling open/closed...

    U0101

    On the grey plug at the TCM I have confirmed that the grounds in pins 1&5 have continuity to the engine and to the battery negative. I have also confirmed that the Orange wire in pin 3 has constant 12.3v with the key off. The pink wire in pin 4 has 11.8v with the key on. The schematic I have...

    I checked/cleaned the ground connections at the front driver side cab mount, under drivers door, and from engine to cab. Besides those three what other grounds are there? Can anyone telle which pins in the TCM plugs are supposed to be power and ground?

    U0101

    As in a bare and/or pinched wire or a plug somewhere not making full contact? I have taken the TCM and ECM plugs off to look at the pins and from what I can tell they look fine. Any particular spot I should be looking first? Any way I could somehow narrow it down?

    U0101

    Had cab off to do head gaskets, put cab back on and got truck running again. Everything was working fine after a few short test drives besides a fuel pressure code (P0089). It then sat for a few weeks and now I insure it and am ready to put it back on the road then suddenly out of no where I get...

    Remote mounting cp3

    So when the belt snaps or a pulley bites the dust then your pump will stop spinning thus shutting down the engine. Idk about the rest of you but when a belt snaps or pulley quits working Im not gonna have a need for the fuel pump to work until it fixed anyways

    LLY: Fuel bleeding problems

    So just incase other ppl seem to have the same problem I solved it by taking the cp3 apart. I found the valves that let fuel in to the pistons were stuck with gummy old fuel. I removed and cleaned those and the cascade valve. Then I was able to bench test the pump with a hose out of a jerry can...

    Remote mounting cp3

    Just found your old thread. Thanks looks like I'll go a similar route. I'm not a parts replacer kind of guy and am too cheap to just bite the bullet on a new pump so I like the idea of making things easy and accessible. I've had the pump out 3 times in 3 days trying to figure out why I don't...

    Remote mounting cp3

    So basically just need the dual fueler bracketry, pulley, and a new hard line to the rail? Anyone sell just the brackets?

    Remote mounting cp3

    Have my pump out right now and was just thinking why can't I mount it up where the second pump would go and run it off the belt. Wherli(sp?) makes a plug to block off the hole in the block. Seems a lot more simple to me than having it deep in the valley...

    Interesting results with banks six gun and iq 2.0

    There are lots of dealers in canada (especially Alberta) that sell aftermarket tuning, mods, ect... I bought my 05 used from a dealer back in 06 and it came with a predator tuner and was 4" straight piped.
