    5LM60 Knocking Sound

    Jesus! LMC is kind of a gamble from what I've heard. So might-as-well do it the factory way if it needs to come out anyways. Kill 2 birds with one stone ;)

    Of course anytime! And yeah that’s probably the better alternative if you’re open to possibly taking out the dash, but if you’re lazy like me a bolt though will do the truck haha. Just make sure to put some RTV around the bolt if you do what I did, don’t want any water seeping through.

    5LM60 Knocking Sound

    Yeah I don’t see how it could be anything else but the front bearing on the input shaft. Just brought it out to lunch and now I don’t hear it, seems sometimes it does it sometimes it doesn’t. I’m just going to ride it till it dies lol. As for the clutch pedal mounting it’s pretty simple...

    5LM60 Knocking Sound

    Hey yall, in this thread I'm talking about my 94 K1500 with a 350 tbi, recently swapped in 5LM60(swapped from 4l60e automatic). Drove the truck today and all went well until I pulled into the driveway and parked it, kept it idling foot NOT on the clutch pedal. I heard a drivetrain knocking...

    I also plan on picking up a USB to ALDL cable soon so I can read live data on tunerprort.

    Bad running after manual swap

    Yeah that’s what I’ve been wondering, I guess only time will tell! I plan on putting new headers on it at some point in the near future. Just worried about snapping the rusty bolts lol.

    Bad running after manual swap

    Truck is still doing good today, rpm’s at idle still fluctuate a little bit just because of the computer with the manual swap, but it’s fine for now. When warming up or restarting the passenger bank definitely does have a misfire. Nothing new, but a misfire that is stubborn nonetheless lol...

    Bad running after manual swap

    Update here again. Tach flutter is still completely gone, drove the truck for almost an hour no problem. I guess I’m back a bit to needing to find a compatible PROM for the manual swap though lol… while it’s not doing what it was doing the idle does still smoothly come up and down a bit at...

    Yeah I do wonder what happened to it; it’s so strange.

    Bad running after manual swap

    Good morning! Update time, and this one is a good one! Fired up the truck and let her warm up completely. The issue seems to be totally gone based on 30mins of idling!!! Tach no longer bounces and glitches at all, and it no longer wants to die! Seems like it was a bad out of the box new ICM...

    I sure hope so! And the coil wire seems to be making fine connection, it was also happening with multiple wires, so that wasn’t the problem. And no problem!

    Bad running after manual swap

    Update folks! Got alligator clips and tested the main 12v keyed coil wire to ignition switch under the hood. Power was fine, wiggled it all over and brought it near the dizzy/intake area, power didn't drop. So I went in the cab, peeled back some insulation and tested there and wiggled some...

    Bad running after manual swap

    Well I’m really spamming this chat up lol…. But big update here, not a good one. Found a stud to use as a firewall ground, ran the one from the frame and back of cylinder head to it, confirmed it had a good ground with the old volt meter. Started it up, same exact problem. So next I tried...

    @1998_K1500_Sub is there any other place on the firewall to ground to from the frame and cylinder head? The one below the heater hoses on my truck is totally stripped and rusted

    And she’s home! First thing it did when I parked at home was have a tach seizure then stall lol. Waiting for her to cool down before I put these grounds in
