I have a 6.2 10 speed max tow Sierra 1500 with 30K miles on it. My transmission problems started with a high-pitched whine that I took the truck in to the dealer to diagnose. The dealer had it from 9-7 to 9-23 and found issues with the torque converter said there were "allot" of metal shavings in the pan, they replaced the torque converter, pump, cover and a few other things in the transmission. Now that I have it back it is making a knocking/ratcheting noise while in 1st gear but stops in any other gear. Also, I feel a mild shake/shudder at highway speed now, the truck doesn't shake beyond the normal road surface vibration, I don't feel anything in the steering wheel, or with my hand on the dash, it feels like my seat and console are shaking. The dealer said to "break it in for 500-1K miles" and it may be a little noisier and shift harder while breaking in.

 

My question is should I be concerned and take it back to the dealer asap or let it go and see how it does?

 

also questioning the long-term reliability of this transmission in the future.

Back at the shop now they are saying the transfer case is bad and that is the new source of the clicking noise in 1st and 2nd gear.

My 2020 Tranny and torque converter were replaced and it's still not right but GM and dealer now push it off and say it's "normal".  This is after the tranny pump bearing failed and tray was full of metal.  It's only a matter of time before the new tranny does the same.   I didn't have any noises, just shudder/slipping issues and still do.

      Oil Consumption

      I agree.   However, the owner's manual, suggests that a drop over full is just as bad as a drop under. (Read black and white letters only, insert no common sense.)

      Transmission Woes :-(

      By asilverblazer · Posted

      That P0700 and loss of power suggests something significant is amiss to me.   More/other codes may suggest otherwise; I would investigate those prior to spending the money to change fluid on a transmission with a bad torque converter.    The relatively sudden escalation of symptoms to me suggests that something began failing (initial shuddering experienced) and rapidly deteriorated (slipping/loss of power). Fluid condition alone wouldn't cause the sudden escalation of problems - though it might have been the cause of the deterioration up to the point of failure.

      AWD conversion to Z71

      By asilverblazer · Posted

      Stabilitrack operation is in a sense a separate/independent operation from the operation of 'traction control'. Stabilitrack is used to keep the vehicle traveling in the DIRECTION intended, it can brake independent wheels and or adjust throttle to influence the direction the vehicle is moving.   This can be illustrated by a 'fish-tailing' example. At high speeds, if the stabilitrack detects excessive yaw (the vehicle spinning like a top, it has a sensor for this), based on inputs from steering angle it determines that the vehicle is spinning out of control, and begins working to control that unintended spin. By reducing throttle input or braking specific wheels to control or prevent the spin.   The traction control works similarly using the ABS system to slow spinning wheels and thus transfer power to 'other' wheels. The goal being to achieve wheel speeds that are all in agreement with each other, the truck then assumes that since all the wheels speeds are the same no spinning is occurring. For example, launching up a wet boat ramp, there is no excessive yaw present, traction control alone can manage the wheel spin by braking spinning wheels and cutting throttle.   Stabilitrack and traction control from a hardware and software standpoint are basically one in the same, I don't remember specifically in 2004, but you couldn't get a truck with one and not the other. The switch on the dash, could turn off the traction control, but not necessarily the stabilitrack.    A confusing comment about stabilitrack vs. traction control, the same components serve both operations, but marketing could advertise them as two separate features.    The AWD system is another separate system entirely, in addition to the other two, it uses the same wheel speed inputs but can also vary the transfer case clutch application to direct some power to the front axle, working in conjunction with the traction control to bring wheel speeds together.   The power split will never be greater than 50:50, the same as 4-high. It will never direct MORE power to the front axle than the rear.

      Start-Stop ?

      Not based on the new photos I'm seeing.  Car and Driver posted additional photos that shows an auto stop start button left of the steering wheel.

      Car and Driver is reporting wireless CarPlay WILL remain, and they posted several additional photos, including a left knee shot, but the only hard buttons there are e-brake, auto start stop, tailgate and cargo light.  Also definitely looks like High Country and ZR2 get micro fiber on the center of the console lid and the ZR2 possibly also on the seats.
