2017 Silverado 6-Speed Transmission Issues - Any Solutions?

Technical Issues
1

Introduction

I’ve been experiencing some concerning issues with my 2017 Silverado’s 6-speed transmission, and I’m hoping to hear from others who might have faced similar challenges. It seems like this could be a common problem, but I’m not entirely sure. Sharing experiences and advice could really help us troubleshoot these issues together.

Common Problems

From what I’ve read on forums and user reviews, here are some of the prevalent problems related to the 6-speed transmission in the 2017 Silverado:

  • Rough Shifting: Many users report a harsh or jerky feeling when the transmission shifts between gears. This can be especially noticeable during acceleration.

  • Delayed Engagement: Some drivers have noted a lag when shifting from park to drive or reverse. This delay can be frustrating and concerning.

  • Transmission Slipping: A few threads mentioned that the transmission feels like it’s slipping, losing power during acceleration, which is worrying when on the highway.

Possible Causes

Understanding the root causes can often lead to better solutions. While I’m not a mechanic, here are a few hypotheses based on what I’ve seen and researched:

  • Defective Transmission Control Module (TCM): A malfunctioning TCM can lead to erratic shifting and other operational issues. It might need a software update.

  • Low Transmission Fluid: Sometimes, low or dirty fluid can lead to problems. Regular maintenance checks can help ensure levels are adequate.

  • Worn Out Components: Over time, parts within the transmission may wear out, leading to shifting issues.

Troubleshooting Steps

If you’re experiencing similar issues, here are some steps I would suggest trying:

  1. Check Fluid Levels: Make sure your transmission fluid is at the correct level and in good condition. If it’s dark or has a burnt smell, it might be time for a change.
  2. Reset the TCM: Some users have found that resetting the TCM can improve shifting issues. This can often be done by disconnecting the battery for a few minutes.
  3. Visit a Professional: If these issues persist, consult a professional mechanic who specializes in transmissions. They can run diagnostic tests and provide insight into what’s going wrong.

I had erratic behavior during gear changes too. It felt like it was slipping and then suddenly grabbed the gear. I’m not sure if it’s a clutch issue or something else.

That sounds concerning! Have any of you checked the transmission fluid level? Sometimes low fluid can cause these issues.

No unusual noises here, but I’ve seen a warning light pop up, which the dealership said was a transmission malfunction. They want to do a full diagnostic.

That’s a bummer. A full diagnostic can get pricey. Have you gotten a second opinion yet?

8

I’ve noticed a whining noise when I accelerate. It’s definitely not normal, and I’m worried it’s related to the transmission.

9

Whining could signify a problem with the torque converter. Have you had it checked yet? Sometimes these noises escalate into bigger issues.

10

Honestly, mine was really jerky for a while. I thought I was going to spill my coffee every time I drove! Has anyone here had a successful fix?

11

Haha! I can relate to that! I finally had my transmission fluid flushed, and it helped a ton.

12

I’m considering trading my Silverado due to these ongoing issues. It’s been more of a headache than a truck sometimes.

13

I feel you! It’s tough when the vehicle you rely on starts acting up. Have you explored any aftermarket warranties?

14

I was able to resolve the issues by getting a software update from the dealership. Apparently, some 2017 models had glitches.

That’s interesting, [quote=“apowell, post:13, topic:1642”]I was able to resolve the issues by getting a software update…[/quote]
So, a software issue could be behind it? I should ask my dealership about that!

16

Every time I take mine in, they say nothing is wrong! Makes you wonder if they just want to keep charging for diagnostics.

17

Honestly, I think they’re just guessing half the time. Maybe we should start a petition for better service!

18

I’ve noticed some shifting issues with my 2017 Silverado too. A friend mentioned that fluid quality can greatly impact transmission performance. Has anyone checked their fluid lately?

19

I just checked mine last week, and it was a little low. After replacing it, the shifting feels much smoother. Definitely worth looking into!

I think it’s a mix of factors. I’ve also read about design flaws in the 6-speed. GM hasn’t been very communicative about that though, sadly.
