How to 4L60E to 4L80E trans swap

[567234ta]

Just an update.

I added a 6qt capacity transmission pan, whoopti dooo, lol.


I actually wanted to post this incase anyone had the same issue.
From the day I installed the transmissoin and the truck was drivable, the converter was doing wierd things. The trans would shift just fine, then the converter would lock up after fourth just like its supposed to. BUT, when I would come to a stop, the converter wouldn't unlock until a 1st gear downshift. This was very annoying and you can imagine how loaded the trans and truck was when trying to accelerate about 30mph, after slowing down.
I tried several calibrations, tons of tuning and couldn't fix it. Chuck suggested I replace the TCC solenoid, I did and now it works. It seems the TCC sol. can lock and work half ass, but not unlock.

I just wanted to post this, it may help someone out in the future.

NOW, the trans and converter are working together great and the truck is awesome!

later,

Thanks buddy,

I'm actually going to send the converter off and get it tightened up. I ordered a 2800 stall, but under mid throttle, the rpms stay at 3000-3200rpms and I can get about 3400rpms during a brake stall.

I'd like to have a true 2800stall in there.
