I admire the patience and precision of your work. I couldn’t do it.

X2. Best of luck with it this round

Oh I'll drive my self insane until i succeed.
Poor wife, she has to hear my ramblings as i try and process information.


And i went to torque down the balancer
damn thing keeps sinking too far!!


fk it, i ordered a "new old stock" balancer.
Found one on ebay for $50

if i have the same problem, then i'll start playing with spacers/washers between the balancer and the timing chain/pump hub.


Everything i find says that balancer is supposed to seat against the sprocket behind it.




And i still have the original sprocket, measured against the replacement from when i did the DOD delete in the 5.3.
They are Identical (minus some hammer marks since i used the old one to seat the new sprocket).

Oh and i totally "cleansed" the hoe.
I'm willing to try anything at this point.


Also Sage sorta smells like weed...

 

[Just Fishing]

And, i reverted the transmission tune.
Put back to stock 5.3 for now...

i have timing pulled so far back, i don't think it will be much of a problem unless i go WOT.

Nice thread! My only problem is that sage smells nothing like weed, sage is disgusting. But I guess I could just be one of those evil spirits that it is supposed to ward off lol.

He had to tell his wife it was sage. We all know what he "cleansed" his hoe with...wink wink.

Was going to post a video about how weed helped a guy not worry about a spot on his workbench but didn't want to trigger any of my brothers on here.

Hey @Just Fishing you seem to be very knowledgeable on the 6l80. May dads 2012 avalanche is starting to have some kind of slip/shutter. At first he thought it was missing under a light load then it became more obvious it was in the trans. I know zero about these transmissions or what is "common" to happen. I haven't ridden in the truck myself but he describes is as not wanting to take off from a red light. Like it's in too high of gear but with throttle, it'll down shift and take off. Sometimes, when coming to a stop, you get stopped but it lunges forward, almost like the tcc isn't unlocking properly. These are the symptoms he gave me. I didn't find much on google though. I believe the mileage is around 120k? Trans has been serviced every 50k. Fluid and fliter

Sorry for typos. Lack of sleep and I don't have the energy to fix them

Might be the pressure switches in the techm.

Mine was doing that a bit, i found some of the laminates for the pressure switches had started to wear through.

The remaining lag or delay it had seemed to be going from 3-4, i fixed thst by raising pressures by 5%, and adding another 5% to the oncoming and off going pressure presets.

After going back to stock 5.3 settings, i did the same thing again.
Shifts much better this way.

Is this something you simply changed in the tune?
