    Build thread - LMG 5.3 to L96 6.0 swap

    Went with the ring on drivers side as suggested, seems to make a good seal, thanks. As for TC mating to flex plate - all is well and i'm 99% sure they are mated correctly and the three bolts are torqued. But I did have a small setback as well when doing this. I brought the engine and trans...

    On weeknights, I only have enough time to do a few things on the swap. Last night it was AC belt, water pump, power steering bracket and pump. Tonight it was exhaust manifolds and some other small parts. New ARP bolts for the manifolds. Hopefully no more broken bolts. Question on...

    Pam drop and filter change today, as mentioned above. Saw some very fine silvery residue in the bottom of the pan. How bad does this look to y’all?

    thanks for all the suggestions. I'll go through them one by one. I'm limited by time and also trying to stick to a budget, so I did have to make some hard decisions of what all to do. Oil cooler lines - I just added an OEM cooler to my truck less than 2 years ago, so I'm keeping what I had...

    Engine in! Got it on the motor mounts and got the trans at the right height, simultaneously trying not to crush any harnesses or cooler lines/making sure they were in right location, getting AC comp in its bracket, etc. Got the dowel pins to line up and got trans to mate part way; had to very...

    Definitely a good thing to check, thanks. There is plenty of clearance, tho. I put all six crank bolts in the flex plate and then lined it up with TC mounting tabs. The way the Luk is designed, there is a lot of clearance back there. With plate snug against TC I could push the crank bolts...

    Didn’t get a chance to work on the project today, but got some yard work done and now I have most of Sunday and Monday free. Plus I was waiting for some bolts today…. A dilemma on the flex plate to crank bolts. Plan all along was to reuse the bolts that came with Jasper engine, as I don’t...

    Input shaft seal and o-ring replaced today, Luk torcon TC filled with 1 qt delco dexron VI, and in place in bell housing. Ready for engine drop in tomorrow. Interesting how much smaller the Luk is than the JMBX. I should have taken a pic of them side by side.

    I have a stupid question...

    My 09 Tahoe had those, but my 13 Tahoe does not. 09 was LS trim with cloth seats and it had a backup camera in the mirror. 13 is LT with leather and none of that stuff. (I added an Alpine head unit with backup cam tho)

    Tonight was installing the last parts on the engine before it goes in. (Except flex plate - has to be off the stand before that) New genuine GM knock sensors New Delphi crank and cam sensor New AC delco iridium plugs New fel-pro valve cover gaskets Brand new OEM GM motor mount for DS and one...

    Engine Oil Cooler Retrofit

    Like others, I've done what you're proposing. I did it in conjunction with an axle ratio change, so I had the front diff out at the time. I also did drivers side motor mount at that time so that gave me some further room...

    LMG is out! Now begins the journey of getting the L96 in. LMG is actually sold and gone already. I advertised it on FB marketplace a couple weeks ago when it was still drivable. Buyer wanted it for an 09 caddy cts wagon! Was going to put a 6l80 behind it. I triple checked to make sure I...

    Yep, I’m not sure how rebuildable these starters are, if at all.

    Floor Jack Recommendations

    I have a 3-ton Arcan that I bought from Costco - I'm pretty happy with it. They have both steel and aluminum versions. I have the steel one - cheaper, and I don't pick it up that often so no need for the weight savings.

    I forgot what a PITA it is to drop the transmission pan NEED HELP w 2 Manifold Nuts

    I got lucky in doing my engine swap - all the manifold flange nuts came off without too much of a fight. You can get good access to one or two each side if you remove the wheel skirts. But what really worked best was a 15mm impact socket with a wobble adapter behind it and then enough...

    Starter hitting flywheel

    Happened to me when I first got my '13. It was most noticeable when idling on a slope (nose in the air) - the starter gear would fall into the flexplate and make one heck of a racket.

    Did the last of my unbolting and disconnecting tonight - including sensors and harnesses on bottom of engine, motor mount-to-frame bolts, flex-plate to torque converter bolts, AC comp to bracket bolts, and other odds and ends. Trans is supported with a ratchet strap to frame. In theory, I'm...

    Ok cool, I that’s what I was thinking but there’s another sensor by crank pulley on front that I thought was crank sensor. What is that one? EDIT: Nvm, I now realize what I was looking at below the balancer is just the connector for the cam sensor. Didn’t realize the the wires from cam were...

    Making progress on the swap. New engine pretty close to being ready to go in. New barbell, oil pickup o-ring, RMS, rear cover gasket, pan gasket etc. added the girdle to oil pump pickup too. Worked a bunch last weekend on getting the LMG ready to pull. Tonight I got out all the bell...
