Just Fishing's 09 Tahoe Build thread

And for the coolant,
I went with a slit in the lid, that allowed just enough control to not make a mess.

With the 5-gallon bucket, and an un-opened 1 gallon mixed in with some distilled water to make 2 gallons.
I had just enough to top off the coolant level.

Lucky!!
But I was prepared to add that last gallon of distilled water I have on hand if need be.

Also distilled water has been rationed here recently.
Wife managed to score some about a month ago for me, limit 2 gallons.

Why is it rationed?

Why is it rationed?

I think it's used for medical equipment.

Took the hoe for a little drive today...























It went pretty well, after a few shifts the transmission started firming everything up.
I'm not calling it gtg yet, but the shifts are "pleasant"
So I need to reduce some slippage allowed in the converter, and up the pressures in the converter a bit after reducing the allowed slippage...

And for the life of me, I can't get back to the menu where it allows me to do the transmission fast adapts, where it runs the clutches and you have to hold the brake while it does it's thing.

I got it to do it once with the knock off tech2, but it's no longer a thing apparently

I think you have to do that through the scanner. There should be an area in the transmission section that allows you to do the fast adapts along "cleaning" if you want. I've not done it personally but that's what I remember from the videos I watched a while back.

Yeah, there should be two options from what I remember, and from what I see in other models.
One to just reset the learned adapts.
and the second to perform the adapt

Maybe it's somewhere else, but I have yet to find it.

Meh, oh well it's doing pretty good.

Mostly I was worried about me changing those clutch clearances so much.
the worry would be if I were to create a bind, broken shells, shafts, etc.

If someone happens to have a tech2 could check to see if it's available on a 09 Tahoe (under K) with a 6 speed...
I'm looking under powertrain, transmission, special functions
Maybe something got corrupted on my tech2

New tune created, upped the shift pressures and the tcc apply pressure by 5%
and I reduced the allowed amount of TCC slippage from 20% to 10%


I also didn't mention it, but I replaced the heater T's with new GM units while I had everything apart.

For the life of me, I can't figure out what the difference is, but this is what my tahoe had, one black, one "white"

I thought about the metal ones, but it was less effort for me to just use ebay.

But after I made the order, I find out about these little plastic gears in the seat lumbar that strip out over time.
And I can hear the motor buzzing, but nothing adjusts.
that same company makes little metal gears to replace the plastic ones.

My lumbar hasn't worked since 2013. I asked questions on here but never got an answer. Hopefully you can figure it out.

Yeah, I did some reading trying to figure out what the issue was early on.
I found some info where this plastic rib cage looking thing breaks and you lose it.
I believe that's what happened on my S10, it made the driver seat terrible to sit in.
Also, a big factor for just buying something else.

One these trucks, you have two types
One is a manual adjustment, lots of info there saying a cable breaks, or some part where the cable attaches to.

I thought this was the part I needed, but then while looking through parts to fix my entertainment system, I ended up in the escalade parts...

Then i see the exact seat I have, and then the lumbar support with motors!!

that lead me down a new road that included gear driven adjustments that resemble the power folding mirrors.
and that lead me to find the replacement parts!

The back of the seat snaps off, from there the motor should be visible.
I just need to confirm I have the correct type and then I'll make the order.

I'll do a write up here and in the interior section when I get there.

So far things are going well *knock on wood*

I still have that valve train rattle sound when the engine is hot.
But it it's quieter than last time around.
I suspect it will get louder when I swap out the 30 weight break-in oil, but the hope is that increasing the lifter preload to .090 helped.

My thought is that I need to go to a full .100 for the lifter pre-load.
But now I can do that via shims instead of expensive pushrods, issue is probably the heavy double pac springs on the AFR heads.
And those lifters state .050 - .100 preload.

I wish i bought different ones this time around.
I don't like the extra oiling feature anyways, and i don't think I need it with the full roller rockers.

Found a nice video telling me how to get the fast learn to fire off using HP Tuners

Adding the FastLearnStatus, it gave me directions to place in Drive.
then a nice status as it did it's thing.

Now i'm stuck in between gears, but that's normal.
IIRC I just need to wait it out.
