6.2 LS3/L99 and 6L80 in my LJ

Recommended Posts

This arrived just in time.  My LJ rolled over 200,000 miles recently and the replacement Chrysler 42RLE has started to slip out of gear.  This is a GM L99 6.2L V8 and 6L80 six speed automatic out of a 2011 Chevrolet Camaro SS.  The stock 190 horsepower has never been enough so 400+ horsepower should do the job.

Just did this exact swap at work in a Scout II and it screams! I would imagine that it ought to scoot around an LJ just fine. Work of caution: the Scout blew up two Dana 44s without even flinching then was replaced with a custom Currie 60.

I picked up a little something to help with the swap and many more projects in the future.  I have help coming out this week to install since the columns are ridiculously heavy.

A service company was by yesterday to help get it all installed so I can working on... more shop cleaning!  There is still too much crap in the way.  Zip ties are totally kosher wire tie downs.  An electrician will be by at some point to rewire the hazards in my shop.  I needed the wire ran for the day of the installation appointment.

Popping the top off was much easier than expected.  I also wired up the welder hook up on the lift supply.

My parents were visiting so I basically missed a week working on this.  Then I had to come up with a solution to get the engine in there since the engine crane is too short.  I am also waiting for a few more transfer case parts to arrive so I can finish rebuilding it and putting it on to do a final test fit.  The fitment with a 1.25" body lift and the AEV Tummy Tucker is pretty damn good.

 

Out with the old...

You are always welcome to come over, but the drive is a bit long.

The current road block is waiting for a 4WD output shaft to arrive for the transmission and a giant snap ring plier.  When I bought the transfer case adapter from Novak I only read the part that it was compatible with both 2WD and 4WD 6L80E transmissions.  Not the part about that being only the truck versions and not the car version I have.  I discovered this while test fitting the partially rebuilt transfer case so now I have to rebuild the transmission as well to replace the output shaft.

The Camaro water pump has a bit of a fitment issue.

However, I did finish rebuilding the transfer case.  New 32 spline input, six gear planetary, and a 32 spline SYE output with a 1350 flange.

This huge snap ring plier for rebuilding the 6L80 showed up on Thursday.  It is the only special tool required to rebuild the transmission and is significantly cheaper than having someone else replace the rear output shaft.

The output shaft on the transmission I need requires splines about another half an inch back.  The Camaro output has a milled section for holding an o-ring seal.

holy cow!  I imagine that's one tool that autozone doesn't have on their loan-a-tool program. :laugh:

So the solution for the throttle body is to rotate it 180º.  More on that later.  For now I removed the front axle to weld in the engine mounts and paint the frame.  I also have to rebuild the Johnny Joints in the control arms as well.

 

No, the welds are not great.  I am still learning and fighting an old welder with a worn out feed lining.

I never rebuild a transmission, but I needed to swap the car 2WD output shaft for a 4WD output shaft along with filling the rear holes in the case.

 

So I rebuilt it on the shop floor.  Working on this transmission was really easy and it just requires a bit of attention to detail.  However, getting all of the clutch packs aligned and sunk was a back aching pain.

I assume I landed this on a rock at some point.  I just have to remember to fix it before painting.  The pry bar had to come out to remove the control arm.

If you can not see the rust your Jeep is hiding it from you.  This lovely tray is perfect at catching and holding debris.

(I forgot to fix that control arm bracket first.)  POR15 with a VHT enamel gloss black top coat.  The welded on nuts for the upper shock mounts were air chiselled off a long time ago.

I am installing Metalcloak's Duroflex arms and the front upper arms require modifying the axle slightly to install them.  The instructions were brief and best summarized as, "Insert circle into round hole, insert rectangle into slot, weld."
