    engine question 6.0 into a 5.7

    Do a search for performing an "LS SWAP." You sound like you need to do some research before making this happen. Largest items are a computer and standalone harness. It can get pricey if you don't plan it out right. Vortec 350 is based on the SBC that goes back to the 60s, and in 99 they put...

    LS swap into a GMT400

    I used current performance for mine, then guess and check for hooking it all up. Wiring it yourself would be a huge undertaking if this is your first time. Sent from my Pixel 2 XL using Tapatalk

    LS swap into a GMT400

    I found all of the wires to the into from the old harness except coolant temp and oil pressure. I used a 3 wire temp sensor with the new green lead going to the old gauge. For oil pressure I used the old sensor with a brass adapter, obviously the gauge will still read and 40 is still excellent...

    1995 K1500 LS Swap TCC Unlock Sense

    Just to update. I was going to do the relay, had everything ready, and didn't have to. Apparently on the 95 and up trucks, there is a wire to perform this function. Sure there are others, but can't confirm. On the blue pcm harness there is a purple wire, keyed hot, and when the brake is...

    That's kinda what I'm looking toward. Just a last question send out before I go that way. Thanks for the instructions! Sent from my Pixel 2 XL using Tapatalk

    1995 K1500 LS Swap TCC Unlock Sense

    So, I would have to plug the pcm back in to get that signal? I'm not running it currently, so maybe the relay is easier? What is everyone else running? Sent from my Pixel 2 XL using Tapatalk

    1995 K1500 LS Swap TCC Unlock Sense

    My transmission builder has gone through this with me and he didn't replace any hard parts. We did replace the converter. I'm just trying to find out which wire is the brake signal wire that's 12+ constant, but 0 with the brakes pressed. Sent from my Pixel 2 XL using Tapatalk

    1995 K1500 LS Swap TCC Unlock Sense

    The previous torque converter, and this brand new one do the same exact thing. Doubt it would be that coincidental. Sent from my Pixel 2 XL using Tapatalk

    1995 K1500 LS Swap TCC Unlock Sense

    No, it just drags enough to cut off the engine in gear at a stop. I never hooked up the tcc wire, but I'm wondering where to hook it up so I don't burn up a torque converter when I find the mechanical problem. Sent from my Pixel 2 XL using Tapatalk

    1995 K1500 LS Swap TCC Unlock Sense

    I have swapped in a 2005 LQ4/4L80E and I am having some issues with the TCC dragging I think. The truck cuts off in R and D at a stop, and driving up to temperature, I can smell ATF (which I believe is cause of the TCC getting hot). I used a standalone harness from Current Performance, and they...
