Subscribing to see how this turns out, hopefully that valve will fix it. Thanks for the writeup and good luck with the triplets!

Parts came in today. Headed out to the shop and installed them after dinner. Good news! I now have all 4 gears, and the transbrake works great! However, I'm still not getting TCC lockup. Solenoid is clicking when commanded through hptuners, but sounds very weak/faint. Could be a wiring issue or a bad TCC solenoid. I'll work on that later. Right now I'm just happy it's actually working!

Busy night! Dropped the transmission to change a leaking front pump seal that I never replaced originally. Then I installed a new tcc solenoid and the updated wiring harness. Don't know which one was the culprit, but now I have lock up! I only have her tuned to 12.5:1 wot, but she pulls like a beast! All just in time for me to sell her . Between the triplets, and my recent decision to run for a local office here in town (tax collector), I'm gonna need the money and get rid of the burden.

What a great thread! Read it from page one. Sorry to hear you are selling the car, but a big congrats on the tripplets! I've been struggling with the idea of swapping out a 4L80E or just spending the money on getting my 4L60E built.

Nice info man. I'll be following along shortly, just nabbed a 2001 4L80e last night.

I was wondering if you ever got a chance to weigh it as it sat when sold? (LQ4, 4l80e, 9")

It weighed 3360 with the 9", ls1, and t-56. Never had it weighed with the lq4 or the 4l80e.

I too am glad you posted this, I will possibly do this in the future here, but I will be getting a rebuild kit and doing some upgrades as well since I am shooting for around 700 to the tire with a 200 shot lol. We will see if my wallet can handle that since I am trying to finish the floors on my house too lol.
