    1998 Fuel Gauge sorta working but not

    I think that’s how you can fool it into thinking the tank is there but I’m not certain

    1998 Fuel Gauge sorta working but not

    I can't find ANY information about these secondary tanks. All I can find is the replacement sending unit. I need the plastic piece that splices into the vent hose where the supply hoses from the secondary tank hook up-but I'm having no luck. I can't find any other trucks or diagrams with the...

    1998 Fuel Gauge sorta working but not

    Yes it used to have a rear tank that I took off. I'm actually wanting to put it back on for extra fuel. Could it be the cause of this?

    Major 4l80e problems

    I’ll tell you with my truck it made a HUGE difference for towing and power. Basically all you need for swap is the tranny a little piece that goes on the tranny cross member to scoot the tranny mount forward without moving the crossmember. Bell housing, flywheel, pressure plate and clutch disc...

    1998 Fuel Gauge sorta working but not

    I know which one your talking about now. There’s one green circuit broad that snaps into a black plastic box on the frame rail that has two plugs that plug into it. The blue wire from the fuel pump goes to it

    1998 Fuel Gauge sorta working but not

    The blue wire completely threw me off. Yes it have a 350 vortec (sadly wish it was 6.5 lol). Is the PCM the thing in the frame rail with 2 connectors going to it? The blue wire i'm talking about runs down to it and plugs into it

    1998 Fuel Gauge sorta working but not

    My 98 has never had a working fuel gauge ever since I got it and changed the fuel pump. At the time I had bought a fuel pump off Facebook marketplace that was actually for a blazer but was brand new and it was all I could afford. It worked just fine although it was a couple inches shorter than...

    700r4 not staying in OD

    So could it be the valve body being messed up? I’ll check for a ground wire tonight also. It was working just fine and then it started to mess up on the interstate

    700r4 not staying in OD

    So do you think it’s the TC?

    700r4 not staying in OD

    Yeah its really hard to explain but its running ridiculous high rpms at 60 mph because its not going into overdive. It stills pulls perfectly fine it just keeps shifting out of OD when you give it throttle. I don't really want to spend more money on it at this point. It just keeps developing...

    700r4 not staying in OD

    Yes I did. I slid it all the way in and use the throttle to adjust it and I didn't hear it but I saw it move out. It didn;t move out or in with my fingers

    700r4 not staying in OD

    Also when I adjusted it I didn't use the pedal I just turned the throttle on the IP

    700r4 not staying in OD

    Adjusted tv cable tonight and still have the exact same problem. When you shift from D to 3 with the motor idled all the way down running ~55 I can hear it shift out of OD and feel it kick down and rev the motor some. If I shift back to D and give it ANY throttle it goes back into 3rd.
