I used HP tuners to tune my transmission on my 2014 Silverado a year ago, best thing I ever did, Truck drives so much better.

[@tonycega]

Been wanting to do mine. Did you use all the same settings from this video? TIA

[@AccessGranted95]

It’s cool to see these tuning videos showing up!

[@mhardy216]

Thank you so much guys! Great information straight from the professionals. A solid refresher for us in the field, and great content to show customers.

[@tampatuning]

Good job HPT 😊

[@MikeHarris1984]

Thank you for this!! I've been using HP tuners since 2004ish erra on my 97 Grand Prix GTP. And used it to tune my various cars, including Camero, GTO, C6 Corvette, various cadi's, and now my C7 Vette and '22 Ford Explorer ST (Purchased new). But I've always been scared to touch the tranny. The Camero I changed the rear gear size in tune as I swapped in a different gear ratio, so that was fixed. But that was the most I've done. I'm going to play with my C7 8L90 :D

[@treybadd]

I literally got hp tuners to do this a few weeks ago

[@arthurnittmann458]

I just followed this video exactly. I know lost my speedo and the abs is coming on. Any thoughts?? It ran fine for about ten miles and then just quit

[@ohfugit]

@HP Tuners Good video! Do these same things apply to an 02 Allison transmission?

[@jeromeirving4770]

I can tell you from experience on 4 -5-6 shift firmness. It's cool to make them chirp into 5th and 6th. But after a while. I only left firm to 4th

[@vtimou5772]

Hello bud !!! do you have any tips on tuning a toyota tundra 5.7...2007- 2013,,, base timing ( and Knock Correct Learn Value, KCLV )....transmission ...not much on tundra s out there...thanks alot,,, !!! nice info videos,,,very helpful !!!!

[@ze3bar]

When i open the max line pressure tables it shows 290.1 psi across the board...

[@abarney1547]

Question, when I change these setting will this have an affect on my WOT performance ? I want the truck to be reliable but I also like to go wide open throttle from time to time.

[@Dusty_Bottoms_]

I have the 8L90 , 2015 Sierra 4x4 6.2 Can I apply similar changes to that transmission? Thanks

[@greghansard357]

Hey Tony, as mentioned below, your first adjustment, 8k/8k rpm on stall management, leaves a non-moving vehicle. What's up with that?

[@LuisRamirez-iu3ji]

Just did this and and in the very beginning you changed stall management to 8,000. When I do that to mine it makes the truck barely move like it's slipping. What is the problem?

[@PHLTHS]

Does the TCC adapt work in fine tuning the apply rate of the TCC or does it monitor the TCC slip against the slip tables and increase the pressure accordingly?

[@treybadd]

I’m no expert… but I have found that lowering the slip error rpm values from from zero and all the way over to 400 have kept my TCC slip at zero or closest to it vs putting higher values there. TCC regulator gain also.

[@vtimou5772]

hi...i have a build cirdle D transmission 6l80...with single disk converter.... should i only use lock up in 6,,,,i do a lot of drag,,,, thanks for your great vid !!!!

[@currybuiltperformance6206]

You can set your lockup at different throttle positions. So no lockup at wot. But have commanded lockup under part throttle/ normal driving

[@mototune5797]

You should be able to lock it up from 2nd onwards. Best thing to do it’s try if locked and unlocked. My car is faster when it’s locked. To be honest this video was absolutely terrible and no wonder there are so many 6l80e cooking the trans…

[@vtimou5772]

@@mototune5797 i think i will have to go with a tripple disk to lockup....im blower with 850 whp no spray and 950whp on spray

[@bryontharp5790]

Do you go to a shop and can they tune it for you hows it work

[@sidvicious01]

What about if you have a shift kit will these modifications still help out?

[@currybuiltperformance6206]

Yes just be cautious that some tune settings may be amplified from the shift kit.

[@sidvicious01]

Ok thank you

[@TheMoody876]

Have had a problem at times where pulling onto the highway the transmission will take forever to shift from 4th to 5th under light throttle

[@currybuiltperformance6206]

You can change your shift timing to bring the 4-5 gear change in sooner. Small changes at a time to what you like.

[@TheMoody876]

@@currybuiltperformance6206 thanks it wants to hang in 4th under light throttle for around 10 seconds at 3000 rpm drives me nuts

[@mvvette97]

how did you get it to display psi on the pressure table? Mine shows kpa only

[@greghansard357]

Click on the kpa and it will change values.

[@kevinlichwa2856]

Need to do more for mustang videos turn on HP tuners

[@Carl_Jr]

Am I required to drink Schlitz before I tune, too? 🍺🍺🍺 🥴
