Damn Transmission….

[GMC-AT]

I have 3K miles on my truck now. And although the trans is a little better.. I still can't get used to it. I love everything about this truck but the trans. I want to hear from others that have 3K +++ miles ... did it continue to get better?

 

I hate how the trans downshifts ( talking about only 30 mph or below) It's like a manual trans with the downshifting. Truck just doesn't "free roll" near as much as my old truck. I even turn off the grade braking.. doesn't seem to change anything.

 

I'm ok with crusing 40+ mph... or highway speeds... everything is fine there. Just low speed sucks.

 

I don't know if I need any of the BCM updates or not... I will ask when I take it in for it's first service. Hopefully there is some software updates that can help.

From GM:

"What you are probably feeling with your coasting downshifts is that we are leaving the torque converter applied during the shifts. We do this because if the trans is backdriving the engine, the engine can reduce the amount of fuel the engine is getting to make fuel economy better. The shifts should get a bit better in feel with miles, but will probably not get to the same feel (or lack of feel) that an older truck [4-speed] may have had."

 

I'm at 6000 miles and mine's still basically the same as when new. Blame the truck fuel economy wars! I think the only way we'll ever get it the way we want is with an aftermarket trans-tune.

that explains it ... thanks Moto.

I can't believe a lot of others that had an older silverado/sierra don't complain about this. Hell we hear people complain about the stupidest little things....but not this. this thing drives like junk to me at lower speeds

Sorry your having problems. Wife and I each have a 14 Silverado and both have been flawless so far. Both shift about like the 2010 that I had previously with 6 speed auto but both trucks are much quieter and ride better than the 2010. She has 4000 miles on her LTZ Texas Edition 4x4 and I have 1000 miles on my LTZ Z71 4x4.

I'm having any issues... the trans is working as it should. I just hate it ..lol

I fought my 09 for 4 yrs. finally gave up and had a mild 89 drivability tune done. Mine was to cure slow down shift and jerking on low speed slow down. Better. should have done it sooner. If I had a new '14, I would try the range and see what effect just AFM off has on driving/shifting. Then go to the tune if it really bothered me like it seems to be with OP.

 

What exactly is the '14 doing on coast down??

This seems like a silly complaint to me.

I hate how mine doed exactly what your saying.. It feels like it chunks... And the -1-2 shift feels like it slips to second

Click here to START YOUR SEARCH.DIGITAL EDITOR ANDREW STOY: I'm old enough to remember when pickup trucks were work vehicles. They still are, but the modern crop of half-ton machines from Chevrolet, Ford, Dodge, Toyota and Nissan are so much more. Really, if it weren't for the still-cringe-worthy fuel economy, only sports car aficionados would need more in a vehicle.Setting aside for a moment the fact that I am a fan of low, lithe machines, the Silverado is a really good pickup truck. The refinement is nothing short of outstanding, with our LTZ tester delivering NVH isolation better than certain fairly high-falutin' German and Japanese sedans I've driven lately. Occupant comfort is equally luxurious thanks to heated and cooled seats, a heated steering wheel, comprehensive automatic climate control, a full gauge package, Chevy MyLink and a side window height ideal for resting one's forearm (as is the custom among truck owners, I'm told).Size? This LTZ crew cab has it in spades, but from behind the wheel you don't really notice. It's amazingly easy to drive, with a decent turning radius, nicely weighted power steering and brakes with confident, linear travel -- it's easy to learn the truck's stopping distances in various conditions, from completely unladen to piled with pea gravel (both of which were tested). For those who trailer, an electronic trailer brake controller is included.The only weirdness I experienced in a long weekend with the Silverado centered on the transmission or more likely the engine/transmission interface. On one stretch of stop-and-go freeway traffic involving braking followed by rapid acceleration, there was a disconcerting thunk from the gearbox. Later, on a hard 3-4 upshift, the engine freewheeled before the gear engaged. Perhaps I caught the new small-block V8 off-guard during cylinder deactivation or something similar, but the issue never reared its head again in several more days of drivingFrom http://www.autoweek.com/article/20131031/CARREVIEWS/131029809

 

Sorry last paragraph only

Hmm. I only spent ~20 minutes test-driving an LT and an LTZ. Can't say I noticed anything "weird" about how they shifted. I did a short loop that was mostly city driving, but included a short highway jaunt as well. I'd say everything worked "intuitively" (to me) ... nothing about how it shifted caught my attention.

 

My only "complaint" about the overall driving experience was the "lazy" initial throttle response, but all that required was applying more throttle input and the truck would get going. But I think it's something that A) I'll get used to driving it on a daily basis, and B) the computer may "learn" my driving habits and adjust to it over time? And C) it's nothing that an aftermarket tune couldn't fix (...dial down the torque management a little!).

 

Guess I'll find out about the shifting when my truck arrives, but again, based on my test drives, I'm not expecting to be bothered by it.

There are multiple ECM/TCM/BCM updates available. The majority have to do with shifting. I thought mine was fine before the updates, and it's still fine after the updates. Make an appt and take an hour to have all these done to your truck, it just might get better.

[mzodarg]

I had the AFM update done yesterday, BCM was done prior to taking delivery. A few on here have complain about transmission being sluggish/hard shifts after the updates. I took mine directly on the highway, 1/4 mile on ramp and I really got on it. Initially the shifting did feel different (sluggish), I ran it up to about 90 MPH, and then did a few pedal to the floor blasts. All is good with it now.

 

I will soon be getting ECM/TCM tuned, I will have the AFM disabled.

Eh doesnt bother me much. My last card (2012 Kia Optima SX) did the same thing on downshifts. Its for fuel savings.

[JRoss14]

I like this aspect of the transmission. It's nice not having to use the brakes as much when coming to a stop in town. I'm glad GM finally starting doing what all the foreign auto makers have been doing forever.
