Not much of an update got a set of my favorite wheels that I've been on the hunt for. Then the beginning of August the corona got me but I'm starting to feel like myself so its time to get back on this project stay tuned. 👍

How'd you catch the bug?

My mother in law provides child care during the week and she works at nursing home on the weekends. One of her coworkers came in to work sick. It was a long 3 weeks, that was the sickest I ever been way worse then the flu.

No, no, no. It's all fake. Haven't you heard? ( ) I keep having to stop myself from unfollowing a lot of friends because of this crap.

Glad to hear you're feeling better. Nice work on the car. Dig the wheels.

Default Transmission

The time has come to start the 4l80e rebuild. This will be my first attempt at rebuilding a transmission hopefully it won't be to bad I have 2 different manuals and YouTube to guide me lol. Think im going to tackle the valve body this weekend, I'm still using the empty case to finish up the engine mounts and alignment. I purchased the main rebuild stuff from oregan performance transmission, then a master recalibration kit from ck performance. I'll post my progress over the weekend. Wish me luck.

And it begins

AFL filter was pretty nasty and had a hole in it.

Wasn't really that bad this was half way through it. Everything has been removed and took it with me to work so it can soak in the parts cleaning tank.

Actually had some free time to mess around with the car. My buddy got the mounts tacked together for fitting they just need to be finished welded and find some spacers.


They also have a brace in the middle i forgot to snap a photo of it.

Either going to run a spacer or trim that outter edge, depends if the mount is molded to it. What do ya'll think I should do?



Sits on the rack but spacers should help with that

I see no issues using big spacers to get just the needed clearance for the rack.

Default Transmission work

Went over to my buddies shop with some of the the trans parts that need drilled per the ck performance kit. Drilled thr separator plate, which I need to call about because they had some holes circled in the diagram that didn't need drilling. Drilled the pump relief holes and the feed holes for the center support. Hopefully I'll tackle more tonight.


Enlarged drain back

Tiny little hole

I took the shaft to work with me (have a better parts washer) got it cleaned up and used some soft Emery cloth on it got most of the bronze bushing off. What do yall think new shaft or let it ride? If do get a shaft I'll probably go with a CK performance one.

Washer stacking, plan on getting some steel tube cut to the same size as the washers for a cleaner looking spacer.

After posting this i realized there was an extra washer on the driver side.

Good tunnel clearance.

Alot better pan clearance might remove one from each side (2 from the drivers side since I had an extra) to get more bite on the mounting post nuts.

Hoepfully ill get some time to work up a transmission bracket this weekend.

Default More transmission stuff


Ck performance master kit

Toasty roasty lol

Clutch disk

Toasted clutch disk

Loaded with clutch material...

This doesn't seem normal to me

This shows a good bit of wear also so I'll probably write this one off and source another good direct clutch assembly.

The center support was pretty much straightforward to do


Upgraded these with the ck performance master kit

Beefy springs and retainer plate

New teflon seals had to order another set for the other side they didn't want to go on as easy as these did. Stay tuned for more just waiting on parts to come in.

Nice setup, are you going to integrate the LS harness with the car at all or full standalone?

At first I was going to wire in a harness and use a oem Silverado ecu but im leaning more toward a holley terminator x max setup.

Not much happening most of my parts to finish the transmission is held up at USPS hub so time to tackle some small things.

So canton wants like $20+ for a pan plug. Luckily i have a well stocked advance auto 5mins down the road so i picked up this plug for $3 and a trans mount for $25.

Pan plug installed

Also looks like the oem lexus transmission bracket is going to come in handy.

Tail shaft hangs roughly 2.5 inches past the mount which isnt to bad

New energy suspension mount installed.

Just have to fab up a plate to connect everything.
