'16 CCSB 4700 mi , so far I'm happy, smooth shifting, occasional it hunts, but not the norm .I believe it has adaptive learning, so it learns how you drive.

I like my 6 speed... since BB straighten it out. My 14 Crew with 24,000 and change had 2 bad points. trans and fog lights.

6 speed is now fixed... Fog lights, soon to be.

I find that if I turn off the grade brake and drive in M5 as suggested in another thread the transmission shifts much better than when in drive and this also disables the afm (I don't do a lot of highway driving so not going into 6th gear is no big deal for me)

The funny thing is I notice different days the transmission acts differently....

 

 

So yesterday I drove it all day and everything was fine. I drove it to work this morning, no issues. Drove home from work and noticed the downshifts were harsher than normal. It was cold this afternoon, maybe that had something to do with it ... but it was cold this morning too and I didn't notice any issues.

 

 

I turned off grade braking and it seemed fine again. It is like the transmission has a mind of it's own on different days.

 

Anybody else feel like this?

I'm on my third truck with a 6 speed. 2007 2500, 2010 1500, and now a 2015 1500.

 

I have no complaints. That was one of the things that I liked about the 2015 I bought vs. getting a 16 or 17. I just read some not so glowing reviews of the 8 speed and knew what I was getting in the 6 speed.

 

Mine have all been bone stock and I love them.

I'm amending my view of "indifference" to generally liking. It seems to have learned my habits and downshifts at the slightest throttle provocation, waits to upshift until grades have plateaued, and always seems to know which gear to be in nearly as much as when I drive my '84 GMC (with a manual). After hitting 22.3 mpg with nearly 2000 lbs in the bed on a recent 170 mile highway trip, I'm more than fine with it.

 

Now if the truck could only be as good in the snow as the X3 it replaced...

Has anybody has their 6 speed in for a transmission update lately? Are there any TSBs out for the 6 speeds? Seem a lot of 8 speed TSBs out for clunks. I would be surprised if there wasn't a software update for ours as well.

Does anybody know if the 6-speed has Adaptive Learning or something similar where it learns shift points over time? Does anybody know how many miles it takes to do that or if it can be reprogrammed somehow?

Yes, it does have a learning curve. I do not know how long it takes but I have read that it can be reset by pulling the battery cable.

When I had my truck in for new headlights (wider spread / free) and lower the volume of the warning ding, they had to reprogram the entire truck, took 40 minutes, then the truck had to relearn shifts and took about 1 hour driving to feel like the old truck. Also my XM was like day 1 with traffic & weather included for 1 month free ...

I am generally happy with mine. Once in a blue moon mine will make a funny shift.

My 2015 was a hard clunking POS.

 

My 2017 is generally smooth; it's just that I can hear it downshift into the lower gears; 3-2 2-1

Kinda like a popping clicking sounds.

Also when coasting down hill when it lets loose of the gear it's currently in and grabs the next gear up I hear the same sounds, pop click.

 

Anyone else have this, hear this?

(2017 5.3 6 speed)

 

 

In my opinion no transmission should make noises like this, weather it's a $20k small car or a $50k full size truck.

 

The question is, is there going to be any long term damage being caused due to whatever noises I'm hearing during the shifts.

Try turning the key to "ON" (but not starting) and holding the throttle to the floor (not going to flood with throttle by wire and a fuel pump) for 30 seconds. This is how one would reset the transmission adaptations on a BMW with a GM 6 speed, so I'm thinking the programming is the same.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.
