    NP241c pass drop 4lo signal

    So I have a 1994 4L60e transmission and ecm. Been running it for awhile now with a np241c from a suburban for pass drop. It only has the 2 prong switch for the 4wd indicator light. What have people done for the 4lo signal to the ecm to adjust for the gearing change? Easiest is obviously a toggle...

    Detroit 6.5 or Cummins 12v

    So I just spent the fall doing a 2nd Dodge restore with my buddy. That Cummins is a beast lol he asked me if I'd ever do a diesel swap into my 85 K20. So I poked around and it seems like a 12v is a massive undertaking in wiring, mounting, suspension, and driveline work. So I went looking at...

    Rattle in oil pan below 700rpms

    A rattle developed last week while parked with the ac running. Thought it was the compressor at first. Got it home to find the noise coming from inside the pan when at idle.

    Trans cooler line threads?

    Done a few thread searches and reading and I'm having a hard time find an easy answer to this. I grabbed an Aux trans cooler out of a 1991 k2500 to install in my k20 that has a 1994 4l60e (same lines as any 700r4). I don't want to use rubber hoses for the fear of failures over time.

I currently have it wired to speed 2, but my concern is that turning on the AC without the fan already running will kick it into speed 2 and draw waaay too...
