LS3 and GM 4L65E Automatic Together
Today I assembled the 4L65E automatic to the LS3. First time working with any of this stuff, including bolting a torque converter to a flex plate. But carefully followed the instructions from Gearstar, plus a few Google searches, and it’s all together. Was especially easy because Gearstar already installed the torque converter, along with a temporary wood piece to hold it back in the right location. That’s apparently one of the bigger mistakes people make, e.g. not getting it pushed all the way in place. Or push it in without being aligned properly. Didn’t have to worry about either. Hopefully not to come apart again. Ready to drop into the chassis when it arrives and starting fitting everything around it. The transmission is heavy and not easy to handle when working by yourself. I put the LS3 back on the crate base it was delivered on and it's going to stay there for now. Then used my shop crane to lift the transmission and the leveler to line it up. When together pretty easily. Torqued all the mounting and flex plate bolts and should be good to go. And just in case someone thinks I missed a mounting bolt, that open hole in the bell housing doesn't have a matching threaded hole in the block. The GM instructions say eight bolts required and I have all eight installed and accounted for. Also as can be seen in these pictures, I removed the stock exhaust headers and taped over the openings. My kit order includes new headers.

Couple other updates. Decided to go with the HGM transmission controller. Was recommended by Gearstar and has a lot of positive reviews and feedback. Plus, little over half the cost of the GM/Chevrolet controller. Made the decision pretty easy. The GM controller requires a laptop. This uses an app on your phone and Bluetooth. Doesn’t matter either way for me, but kind of a cool feature. More wires to deal with when the time comes. I hooked it up and put some power on it. It’s alive and working as it should for now.

Also decided to go with the Lokar Sport Shifter. Specifically, part number ES4L60EFMP. Provides the usual shifting via a cable. But also has a sport mode where you can manually shift up and down by bumping the shifter. Same idea as a paddle shifter without the added complication. Only minor issue I had was the HGM controller didn’t have the necessary wires for the sport mode switches and nothing about it in the instructions. I was panicking a bit thinking it didn’t support. But a quick lifeline to HGM and they had the exact wires and instructions I needed to add them. A little surgery to add them into the harness, but very straightforward and ready to go. The Lokar shifter also has a park and neutral safety switch, so will be able to wire that into the build as well. Not a cheap piece, like most Lokar products, but appears to be very well made and high quality.

Finally, Gearstar sent me a video on my transmission on their dyno for final testing. Kind of interesting. Have done a little poking around learning what’s inside these things and how they work. Quite complex and this is a simple one by today’s standards.

That’s it. Pretty much running out of things to do and my completion date is still 7 weeks away. I guess that means more home projects for now. Plus driving the Coupe as long as the weather allows. Turned 1,700 miles today. Love it.
About to kick this thing off
Last Saturday, 12/5/2020, was my production completion date at Factory Five. Final payment completed the week before. Today I received this picture of the truck in the rack waiting to be picked up. Stewart is scheduled to do just that next week, and they're estimating to be at my place on Saturday, 12/20/2020. So a nice Christmas present! Received word my Wilwood brake package is on the way. No word yet on the Moser axle, but it's ordered. Should be hearing any day about my wheels. Lots of moving parts to one of these projects. But most of you know that already. I've tinkered with the Coupe about as much as I want (or need) to. Finished the last of my promised home projects. So let's get things going. Next post will hopefully be with a big semi in front of our house and the truck in the garage shop.
