Was able to source a trans from a wrecked car w/143k on it. Drove 6ish hours round trip to bring it home today!

Yesterday I wanted to try one last time to get the brake actuator happy and make sure any air was evacuated.

I took the wheels off, inspected all the brake lines/bleeders, tightened and cleaned for good measure. I wound up running through another bleed procedure and rather than use my power bleeder, I employed my brother to work the pedal. I put DOT4 in with the last bleed and repeated that this time. Used my scan tool to run through ECB invalid, zero down/zero down rear, and a linear valve offset.

After 400 miles of driving since the procedures and no weird braking or lights on the dash. Hoping it sticks that way.

Next up is the trans swap! I’ll most likely do the motor mounts at the same time. Already bought new ones from lexus but have been lazy about do the job.

More to come soon!!

Hey! Happy to have found this subreddit. I’ve made some posts in the Lexus subreddit but want to share it here with you all!

112k, put it on a set of wheels off a 2021 LS500. Bought as a non runner with a bad starter.

Replaced:

Starter

Oil dipstick reseal

HPFP seals/ Valve cover gaskets and all the o rings

Spark plugs/tube seals

VVT solenoids

Valley Plate/ Crossover reseal

2 Direct injectors on driver rail (broke when harness unplugged for valley plate)

New DI/knock sensor sub harness

Intake manifold/throttle body gaskets

Water pump

Radiator

Serpentine belt

New fog lamps/restored headlamp lenses

Oil filter housing o rings at the block

Aluminum oil filter cap to replace plastic one

Fuse block under hood by passenger headlight (ABS relay fault)

Driver rear air strut

Front Lower control arms

Inner/Outer tie rods

Front sway bar bushings

Bank 2 Sensor 2 O2

Rubber brake hoses and bleed all around

Charcoal canister box

Gas cap

4 transmission drain and fills

New Valve body

New SLT/SLU/SL2 solenoids

New strainer filter/oring & pan gasket

So I have a semi regular trans flare/neutral surge that’s going to have to get fixed. Much better post service but either a rebuild or replacement of the trans is due.

Post brake bleed, I’m getting a recurring C1344 fault. I’ve drained the reservoir with a baster and replaced with fresh fluid as well. Fault will clear for a day or so after I perform Zero down & Linear Valve Offset procedures.

Looking at a new brake actuator assembly I’m sure but am not 100% sure of the most current P/N that’s recommended to be installed. There have been a lot of super secessions.

EDIT: PER LEXUS CURRENT P/N is 04003-45450

Hoping to get some guidance or advice on next steps. I can’t seem to find anyone who wants to take the challenge of this trans on and I’ve done all this work at home in the driveway. I don’t have the means here to pull that trans and get it rebuilt myself.

Thanks for taking a look!
