What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[iamdub]

That's how they work, at least both of mine. It's not violent in the way of slamming, it's just sudden lock and unlock. As per a super smart man meats, aftermarket toque converters don't like to ramp in the lock up. They need to either lock or unlock. None of the easing into it

I'm just comparing it to stock and it seems to be too abrupt. It could be perfectly fine and I just don't know any better.

I see an "apply ramp" map that has an axis for slip rpms and torque.. values from 1-1000.. no idea how that works.. guessing 1000 is minimum pressure and 1 is full pressure looking at the map

I don't have these settings. This must be exclusive to the 6L80E.

it's amazing how much they want for wipers these days. I walked in once to get some on the ride home on my car that has 24in wipers. I was in shock when 2 would be 50$. they said it's a dollar an inch these days. I drove home with bad wipers lol.

if you have the kind you can pop off the end, like most oem blades. I've found you can still buy the rubber itself super cheap off ebay. like 3 sets for 5$ shipped. just take a month to ship, so buy like 20$ a year worth. they look identical to the rubber in auto parts store blades. work great and I find myself swapping them much more often because of the price. so they work better for me lol. I have 4 cars to keep blades fresh on and tx sun to eat them up in no time and then random violent storms out of nowhere to drive thru.

$8.73 each on amazon and these are really good wipers, they beat the $50 wipers ($7.17 each rockauto)
I can confirm no lifting @120+ in the rain

Yeah? How does one make the TCC engage smoothly? I thought that was the point of it being a PWM-controlled style. Maybe it's the nature of the beast or maybe I got a faulty converter. But, mine has always locked up abruptly. It's like cruising at a steady speed in a car with a manual trans while riding the clutch just enough to have it slip and raise RPM, then suddenly dumping it. Not violent, but much faster and more harsh than I think it should. I see all kinds of settings for WHEN the TCC engages, but nothing for adjusting HOW it engages.

I don't have these settings. This must be exclusive to the 6L80E.

Just got caught up on everything, yeah, six-speed has a stupid amount of settings. So that must be part of it, but also like the others mentioned and aftermarket lockup is a bit different than the factory lock up.

Changed my wideband from gas stoich To lambda.

those aren't that bad of price, I guess O'Reilly's was really trying to rob me that day lol. but yeah, I like just sliding the inserts out each time costing me about 2$ worth of stuff. plus I just keep them stashed in each vehicle.

those looks like the design of most of the. factor wipers on my car. never had a lifting issue. but I'm also not going very fast in the rain these days.

Changed my wideband from gas stoich To lambda.

man I've always meant to do that, I get why it's better to think in lambda then afr but man I just can't recal my brain. to many years of looking at a/f numbers, it's like adding an extra step of math in there.

Yeah, I've been the same way.
Since I'm switch between gas and e85 I think lambda will be easier. Just with the hpt tables were in lambda to make it easier yet. We'll see how it goes, need to change my scanner to output lambda now too I suppose.

ya the factory and factory like wipers start lifting off the glass around 85mph and become ineffective, they will hit the bottom and top and skip the middle.
the bosch (the $50 ones at retail or copycats) are a little better than oem style and are generally all you find out there for performance blades at least around here anyway.
I didn't want to pay $50 for the bosch anymore so I started researching wiper blades and found these trico, nobody carries them around here so I just order them online, cheaper anyway I am sure they would be $50 at the store as well

I've had a few bosch and rainx $50 wipers on other vehicles and they wouldn't contact the edge of the windshield. Got some michelins from costco about $8 a piece and every bit as good if not better. (Sorry no high speed testing!) But I'll never buy $50 wipers again.. or $75 silverstar headlights.. ripoffs!

anyone try the silicone blades tire rack sells? some kinda life time thing I seem to remember

I uses these and I keep a spare set under the back seat. Work fine for me.

Mike Z71, please take some pics. Happy hunting, bro'.

regarding wires thru firewall.. punctured the outer boot.. that thing is tight! was worried about pulling too hard next to other wires anyhow. I was feeding from inside cab to engine compartment. Had a stainless chopstick sil-glyded up.. but couldnt angle it enough and poked through. Might have a chance if you go engine compartment into cab, but the power wire for upfitter switches had a bulkier terminal on the inside, only had to slide a ring terminal on the other end.. think i got the yellow wire wrapped around..

probably just leave that yellow wire, distributes the stretch more evenly, yea thats it! actually meant to run in one loom, but it wouldnt fit what i had, so i seperated them..

I put Aquapel on my windshields once a year and don’t use the wipers over about 40. Just shut them off, windshield stays super clear. The only time I use them at all is on the lowest intermittent setting for under 40, around town driving.

Ya, I have some stuff like that sitting around here been too lazy to apply it, lol

I tired rain-X years ago and it made the wipers jump when I had to use them. Never heard of the aquapel

trico makes some stuff also which is what I have sitting in my tool box for the last year and half...

It’s way different that Rain-X. It’s the only one I’ll use. Not only does the water run off but when I use the wipers, it acts like the wipers are turbocharged- it’s hard to explain. They just work way better than on untreated glass. The water is pushed ahead of the wipers. Plus it lasts me the entire part of the year it doesn’t rain here, like 9 months. And it never yellows or gets streaky like Rain-X. Not sure about the other similar ones. Aquapel has been around a long time, it was invented by PPG, a big manufacturer of auto glass. FWIW it takes me 2 of the applicators for each of my trucks. They state one will do “ most” windshields but I feel that’s for smaller ones. I could probably use 1 1/2 but I never seem to want to do both trucks at the same time, you have to work pretty quick.

Of course.

I want a 6-speed, but the kind that requires a third pedal. To hell with tuning, I'll let my left leg control engagement and full lockup to my liking.
