Perfect job, I wanna do the same for my 8L90 Camaro. Please, can you share us more info. Did you changed just port throttle shifting? Or you did more things!?
I have the same truck with 6.2. How do they do remote tunes on it? I have a Diablo sport and it can’t access the tcm on this particular trans and I was under the impression that the only way to tune this trans was by physically replacing the tcm
I got a question bro I had a 2016 Silverado single cab that when it shifted the first gear it would give a nice pop to it I even changed the exhaust to a dual corsa and it still mad that nice pop so now I got a 2017 less miles 4x4 single cab and this one doesn’t make that pop shifting that first gear
I'm not sure if the tuned fixed your problem but I too had an rpm flare followed by a slip between 2-3 gear. Dropped my truck off yesterday and the dealership just let me know my torque converter is bad
@@jackstoepfer1494 I guess people were just trying to find something to complain about. I was just asking anyways because I had the idea of swapping an 8L90 in a 496 powered 2500hd. The 4L80 just doesn't have enough gears to play with.
@@jackstoepfer1494 theres no controller for the 10 speeds sadly but there is an 8 speed controller from zero gravity performance and even then it's not really a controller but a piggy back computer from what I understand you gotta splice a tps and such
LL7 the trans tune did not impact mpg at all. The engine tune sure did. For my basically stock truck I believe it wasn’t worth the money and hassle. If my truck has more mods or I wanted it more race feel, it’d be worth it.
@@jackstoepfer1494 I gotcha, I currently have my motor custom tuned by 5 star tuning and gained more mpg from that just wondered if the trans tune would change any.
@@jewllake for a stock truck I don’t think the trans tune is worth the money. As far as mpg, I’m at 60k miles and averaged 19.4 from day one. Pretty impressive for a full size truck, through winters, mostly city.
@@jackstoepfer1494 thanks for the reply...... So you've upped the RPM and pressure? I've shortened shift time 20% so far, just getting started with HP Tuner.
@@jackstoepfer1494 I bought a 6.2 L86 and 8L90 without any harness. Bought from PSI-conversion ecu and tcu with harness. and a "stock tune" So I think it's unlocked, but not properly tuned.
That is 100% due to molding flash/burrs on the plastic in the factory airbox thats in front of the mass airflow sensor. Sanding those edges down fixes the harsh 1-2 light throttle shift like in parking lots.

That WOT is crisp, the 2-3 stock is sluggish.
This makes me very excited for my l83 swap with a built 8l90 into my colorado. Crazy acceleration compared to a 6l
MickleMackleMor crazy factory power w amazing mpg
What year colorado?

FERAS DISHLI my tuner did it all. Frumusa Performance from Victor NY.

You have to send your tcm to hp tuners to get unlocked. I recommend not using the Diablo and have a tuner use hp tuners to update your truck.
Where you in 4High then shifted to 2High in the WOT? Curious because I ran it in 4High but don’t know if I should leave it or switch it to 2high
Yes after it gets rolling and I don’t worry about traction, I’ll turn it to 2wd.
@@jackstoepfer1494 Thanks! Looking to run my truck at the track , Didnt want to go all the way in 4High
Who did the tuning on your truck?? Not many choices for these 2017 and newer GM trucks, thanks
Braydon Beamish new era performance in Rochester ny. He does remote tunes if you are not local.
61 mph 7 out of 8 gear at 1248rpm
Did your truck down shift really hard at wot before the tuning?
No. Seemed to be normal downshift
How did you do you want your transmission to go over 6000 RPM I have a Cadillac Escalade 2017 I could not let the RPM go over 5800 With HP tuners
Take it to a tuner
I got a question bro I had a 2016 Silverado single cab that when it shifted the first gear it would give a nice pop to it I even changed the exhaust to a dual corsa and it still mad that nice pop so now I got a 2017 less miles 4x4 single cab and this one doesn’t make that pop shifting that first gear
my 2015 gmc sierra single cab does the same as well in 1st and 2nd gear
That’s ignition. All good
That truck looks fast. I have the same one. Trans flairs big time when it shifts so who can fix that? I got 6k on my truck
Eric Buchta mines tuned. Corsa and volant. Check my other videos for track and dyno numbers
I'm not sure if the tuned fixed your problem but I too had an rpm flare followed by a slip between 2-3 gear. Dropped my truck off yesterday and the dealership just let me know my torque converter is bad
Folks have said these 8-speed 8L90s haven't been the nicest when it comes to longevity/reliability. How's yours been?
64k miles and no issues. Towed car trailer couple thousand miles too

@@RBLUS_TY if your going that far w a swap, I’d do the 10 speed. 8 is nice but 10 is better
@@jackstoepfer1494 theres no controller for the 10 speeds sadly but there is an 8 speed controller from zero gravity performance and even then it's not really a controller but a piggy back computer from what I understand you gotta splice a tps and such
@@jackstoepfer1494you have to delete the transmission thermostat
I got a 2017 high country 6.2 with the 8 speed an can’t find a place to tune my tranny who did you have so your trans tuning ?
Frumusa Performance
Did you gain a lot more mpg when the trans was tuned ?
LL7 the trans tune did not impact mpg at all. The engine tune sure did. For my basically stock truck I believe it wasn’t worth the money and hassle. If my truck has more mods or I wanted it more race feel, it’d be worth it.

@@jackstoepfer1494 are you saying the Trans tune was not worth it; or both? I'm thinking about tuning my 6.2 once the warranty runs out.
@@jewllake for a stock truck I don’t think the trans tune is worth the money.

@@jackstoepfer1494 did you notice any acceleration diff with the trans tuned compared to factory?
How is the transmission holding up so far?
Perfect. Around 85k miles. Zero service. Didn’t even change the fluid/filter yet.
How was the shifting behavior modified?
How's it acting different from stock?
Shift rpm was lower stock and also the shift was softer
@@jackstoepfer1494 thanks for the reply......
So you've upped the RPM and pressure?
I've shortened shift time 20% so far, just getting started with HP Tuner.
My 8L90 takes about 1,5 seconds to shift from 1st to 2nd. could it be a tuning issue?
Is the trans unlocked and tuned? Or still stock
@@jackstoepfer1494 it is unlocked I think, but stock tune.
@@sigurursigurjonsson5217 why would you spend the time and money to unlock it and not tune it?
@@jackstoepfer1494 I bought a 6.2 L86 and 8L90 without any harness. Bought from PSI-conversion ecu and tcu with harness. and a "stock tune" So I think it's unlocked, but not properly tuned.
So this isn’t the superchip shift point to make it shift like that?
No
Any issues with the 8speed transmission before the tuning?
pipedesigner zero issues
That thing rips!
James LaJaunie thanks. Made just under 400 rwhp on the dyno. Intake. Catback and tune.
Jacks Toepfer is that safe ? I have new Sierra and I’m worried about the warranty
khaled samy very safe. I get better mileage than any other 6.2 I know of. Average mpg over 22k miles is 19 mpg
Did he ease into WOT?!🤔 I have a 16 silverado 6.2 8spd trans and If I put it to floor it burns rubber like a vette everytime I love it😂
Is yours 4x4 and crew cab? Mine only lays rubber in 1st and made 400 wheel
@@jackstoepfer1494 yes correct 4x4 6.2
Crew cab
Traction control is a strange thing
Wainting for the turbo .....
Abdulaziz Aleissa i have one for my car. When I’m bored w that I’ll Turbo my truck again.
Is this stock other than tune?
The Ace catback intake tune. ruclips.net/video/Fzd7Oh-WOv8/видео.html
You tuned the transmission? Tcm unlocked?
Chameleon Tuning yes. Unlocked and tuned
Jacks Toepfer who did you get to tune your trans? T87A TCM correct?
Hey how did u tune your tranny? Please.
My tuner did.
@@jackstoepfer1494 can you tell me what tuner is that so I can do the same?
Can you tell what tuner that is. I have the 5.3 Sierra 2016 with the 8 speed transmission and I would like to do the same.
@@williegaines5178 frumusa performance out of Victor ny. His name is Mike.
Thank u.
Lol I put a cold air intake on mine n it drive way better
That is 100% due to molding flash/burrs on the plastic in the factory airbox thats in front of the mass airflow sensor. Sanding those edges down fixes the harsh 1-2 light throttle shift like in parking lots.
