Diesel Insights - Allison Transmission Learning

[racrx]

Your videos are always informative and technical. Good stuff 👍🏻

Thanks for posting this yet another informational video. After purchasing your guys 5-6 speed conversion I’m going through this relearn process currently. I’ve talked with you guys a couple times by phone and now it all makes sense. Thanks guys!

Excellent video. To the point without fluff with the right amount of detail. My question - will the same principles apply to a Ram 68RFE transmission?

Great advice for my 2018 GMC Denali with a constant 2 ton payload!

[justinledoux]

So I have your tcm tuning as well. You didn’t mention how that plays into how the transmission functions.

Great video...I'm learning a lot from your stuff.

Now that's interesting! I just bought an 02 8.1 liter gasser, my first Allison so I have nothing to compare it to as far it's shifting feel. Does this technology apply to the 02 Allison?

With regard to your comments in the last few minutes of this video, is it better to stay in one tune or the other (mileage tune vs. Tow tune) for the transmissions sake?

I pull a trailer(15, 680 gvwr dump) on the weekends, then drive empty for most of the week. I've always gone back to the mileage tune when empty. This makes me think I should just stay in the tow

Thanks for the videos, still learning alot

Excellent video. Very informative. Thank you.

I don't think I've ever done a 100% throttle 5-6 upshift...

i bought a lp5 and my trans made a loud bang a couple times. never did it again

I have a question maybe you or one of the followers can help with... 05 Sierra duramax 5speed 290k I don't believe allison has ever been rebuilt.. I had a slight shudder when torque convertor was locked in (via edge monitor) I hauled my 30' bumper pull camper 850 miles round trip and now the shudder is horrible in 4th and 5th gear when tc is locked in, I did notice this usually happens after tranny temp hits 108° and up. Plan to do a service with both filters.
Also noticed that when brake pedal is applied when tc is locked it does not disengage like it should, my new brake switch just arrived today.. Hoping one or both helps as I don't have the funds for a 1200-1500 converter and labor

Had to replace the NSBU so I unhooked the TCM for electrical testing. Will I have to put the trans through a relearn again? I also have the 8.1 not Dmax if that matters

[man-a]

So what if I had a TCM failure and had to swap it out? I bought a pre-programmed one from Ryan’s Diesel Service, direct plug and play. Does this automatically put my truck into relearn? Or do I manually do that? Or do I even have to relearn?

Hey guys, great video. Not so quick question for you... I recently bought a 2019 L5P, I installed a banks tuner at 500 miles and as recommended by Banks, daily drove on their highest setting. One time getting onto a highway I gave about 3/4 throttle and transmission stumbled and went into limp mode. After disconnecting and reconnecting the battery the truck was fine, until it happened a second time. I got pretty annoyed and took the tuner off and haven’t had this happen again (currently at 2000 mi) however when I’m in 3rd gear, I believe I’m feeling the torque converter lock and it drops about 2-300 RPM and just feels very odd, almost as if it’s two gears within the 3rd gear. This is my first Duramax/Allison combo (coming from a 6.0 gas 3/4 ton decided to upgrade to diesel as my horse trailer was putting a beating on previous truck). I’m not sure if the truck was shifting this way before the tuner/if it’s normal or if I’m freaking myself out for nothing. I had GM perform a reset of the transmission a few hundred miles ago but nothing has changed, so I’m wondering... is this normal, or, is my torque converter engaging too soon/at the wrong time? Sorry for the huge question... just a noob diesel owner here.

What if your smallest tune is around 600hp?

[joshherrell]

My truck is tuned with Ez Lynk (A.R.T.) and i just started using an Edge CTS3 and i have the EAS SOTF installed, now that i can switch tunes on the fly should i do a relearn with the CTS? I'm on a 75hp setting and the tranny shifts nicely as it always has. But would a relearn be beneficial to the longevity of my transmission??

Was that clip at drag strip in a square body?

Great video Nick. question for you guys.. I did a 4" FloPro exhaust, FASS Lift Pump, CP3, Wehrli full intake with downpipe, EGR Delete, then am doing the 1-5 PPEI Tune (30-150hp), do all of these tips on how to have the Allison re-learn/adapt apply if I haven't touched the Transmission? I would assume yes as it would make sense, but just wondering if there are any other tips for a guy who isn't doing a new transmission. Thanks for any help or just confirming I should go through all of the 1-2, 2-3, 3-4 etc on each of the 1-5 tunes (And back down).
