Who else is having a transmission issue? I saw the thread about hard shift into 2nd, but towing yesterday at 65 mph the transmission literally jolted the truck like it fell out on the freeway, scared the sh*t out of me. Also under acceleration it feels at times like it cant find the right gear, hesitates a bit then finds it. Also when decelerating, letting off the gas it paused then hits. Wanted to see if anyone else is having similar issues. Ive taken it twice to my local dealership and both times they say "Sorry, we couldnt get it to replicate for us, here are your keys."

Mine has awful shifting into 2nd either up or down shift. Sometimes it's OK. Last time I took it in I asked to check latest TCM software he said it had latest. My truck was built in July and have had since end of July can't believe they haven't come out with anything to improve this.

I have a 2014 Denali with the 6.2 and 3.42 rear end. My transmition has a awkard shift into second gear. The dealer said that this is normal because of the low first gear. Of course that is BS. The true is that these trucks have all been programed for max fuel economy. We will all have to wait for a an after market tuner to fix the driveability issues. I like my truck, but it could be so much more. I came out of a 2010 Tundra. The Toyota had a very good drive train.

 

I wish GM would learn that most people buy a truck because it's fun to drive not because of fuel economy. Or atleast that my opion. They should offer two programing options. One for fuel economy and one for those of us that want the best performance possible from our trucks.

No different than my last two Ford's with the 6 speed. Wish I had a dollar for each time I had those reflashed as well.

 

This Chevrolet shifts no different.

you hit on the problem right there. now that things can just be re-flashed, the manufactures don't feel it necessary actually validating the system when they can just send an update to correct a glitch or even work around an issue with the hardware

The Diablosport tune did wonders for the engine and transmission. It is a whole different truck now.

 

Hmm, I need nerf bars, but sounds like Lew Tune is what may be next immediately

Same with my truck. One instance I was in the turning lane slowing down with brake slightly waiting for a car nine left lane to pass so I could pull into said lane, but, as the car passed I took my foot off the brake and hit the gas to get in the flow of traffic and the truck did nothing, I mean nothing. Like the truck was engulfed in a stupid confusion, it sat there while I pressed the gas pedal further and further getting pretty worried about the whole new set of cars getting bigger and bigger in my mirrors. I took my foot off gas and pushed back in and it finally roared forward spinning the tires like I was 16 all over again, only this time I was scared...

 

The transmission has acted up from time to time but a similar incident may have the potential to cause a wreck given the right circumstances.

 

Wasn't towing anything. Completely stock sierra 5.3 2wd 3:42 gears.

      Wow I'm in a pickle. (Broke down truck) and a story.

      I suspect at some point in the near future, the hardware will be free and you pay a subscription to access the vehicle - alldata style.

      BAK MX4 EZ-Lift Install and Review

      By parthery · Posted

      I've been eyeing an upgrade to my tonneau cover for a bit now.  Intrigued by the BAK MX4 EZ-Lift with the torsion spring and went for the upgrade.  Thoughts and musings during unpacking, install and a few days of usage.   Once my order went into Realtruck, it took about 4 days to ship.  Unfortunately, FedEx Ground destroyed the box and contents and it was unusable upon receipt.  To Realtruck's credit, one email with pictures and an RMA was sent to me to send the first one back, and another unit was shipped out.  It arrived 3 days later, unscathed.   I opened the box and it looked like every other BAK MX4.   Biggest differences are the rails and retaining clamps, and of course the spring attached to the cover itself.     NOTE - if you are upgrading from a MX4 to the EZ-Lift, you will have to replace the rails.  The EZ-Lift rails have a notch cut in them to allow the new style retaining clamps to fit properly.  The new retaining clamps also have 2 knobs/carriage bolts and there are two tracks underneath the front panel. The strap clips are mildly different (more like the Undercover Flex clamps) in that the screws go in from the underside.  Personally I prefer these over the BAK clamps that use the nutserts that are a nuisance to install.  The remainder of the parts in the box (drain tubes, rail clamps, and bumper pads) are standard issue BAK.     I did not replace my front bed seal at the time because it seemed to be in decent shape.   BAK recommends shims on the GM trucks unless you place the clamps on the flanges about 1/3 of the way in from both the front and rear of the bed.  I shimmed the front and the middle, and initially placed the clamps equidistant.  This also turned out to be a mistake, because when I set the cover in place, the new style retaining clamps wouldn't clear the front clamp.   New style clamp inserted in the track:     And the issue which occurred because the front rail clamp was too far forward:     Once I removed the shim from the front of the bed, and slid the clamp back to the front flange, everything cleared fine.     The cover set on the rails without issue and I installed the strap clamps.  After I completed my adjustments, I pulled the pin to activate the torsion spring.  Mistake #3 on my part.  PULL THE PIN AS THE VERY VERY VERY LAST STEP!  The reason is, once you pull the pin, the torsion spring is activated.  If you have to loosen the front clamps and adjust the cover, the front panel will - by virtue of the spring, refuse to lay down.  The only way to get it to lay down so you can reinstall and tighten the clamps is to fully open the panel against the back of the cab, which will then allow the front panel of the cover to lay down and be tightened.  Not a big deal unless you haven't installed the foam pads yet (typically the last step) because minus the foam pads, you will need to place something between the frame of the cover and the back window so it doesn't get scratched.  The next time I install one I will install the foam pads before I pull the pin and activate the spring.   After using it for a few days:   The spring assist is great.  You literally can open it with one hand.  My shoulders aren't getting any younger and this was part of my motivation to swap out. The second panel latches and unlatches itself as you open and close the cover.  Neat in concept, however it took me a minute to get used to closing the cover and not hearing the "latching" sound that would tell me it was locked in place. The paddle handles are a huge upgrade and I wouldn't be surprised to see them become the standard across the Realtruck line.  They effectively eliminate the concern that a thief could coat hanger the cover open and get to the contents in the bed. I'm not sure why the very front panel on my cover has a different finish from the other 3 panels.  I have a request into Realtruck to find out if mine was not manufactured properly or if it was by design.   All in all I'm pleased.  Same level of protection, looks good, keeps stuff mostly dry (they all leak around the tailgate) and easy to install.
