Questions about Torque Converter Upgrades for 2018 Silverado

Looking for Torque Converter Upgrade Advice

I own a 2018 Chevrolet Silverado, and I’ve been hearing a lot of buzz about upgrading the torque converter for better performance. I’ve been experiencing some shuddering issues lately, and I’m starting to wonder if an upgrade could help.

What I Want to Know:

  • Performance Improvements: Has anyone here upgraded their torque converter? What kind of performance gains did you notice?
  • Aftermarket Options: Are there specific brands or models you recommend? I’ve seen some options online, but I’m not sure which are the best value for the money.
  • Installation Tips: For those who have done it themselves, how hard is the installation process? Any advice or resources you can share would be awesome!

My Current Setup:

  • Engine Type: V8
  • Transmission Type: 8-speed automatic

I’d really appreciate any personal experiences or suggestions you could share! I’m trying to decide if this upgrade is worth it or if I should be looking at something else to fix my current issues.

Thanks in advance for your help!

I’m considering upgrading my torque converter for better towing with my 2018 Silverado. What kind of improvements have you guys seen in terms of performance?

I’ve noticed a significant boost in acceleration after upgrading to a high stall converter. Towing feels much more stable too.

I agree! The right converter makes such a difference. I went with a Circle D converter and my overall driveability improved drastically, especially when I tow heavy loads.

Did you have to change anything else with the Circle D converter? I’m trying to figure out what else I might need.

No major changes were needed, but I added a transmission cooler to manage the extra heat. It’s been a game changer for towing capacity!

That’s a good point about heat management. Have any of you noticed an increase in fuel efficiency as well?

Actually, yes! I saw about a 1-2 mpg increase on highway driving after my torque converter upgrade. It’s not huge, but it helps!

I’m a bit skeptical about the fuel efficiency claims. The extra power usually means you end up using more fuel, right? Anyone challenged that?

Not always! It depends on your driving habits. More power can mean you’ll drive more efficiently when towing. It’s about matching the torque converter to your needs.

Exactly! If you’re towing, the right torque converter can actually reduce the load and improve efficiency. Plus, driving is just more fun when your truck performs better!

Haha, couldn’t agree more! I never knew I could fall in love with my truck all over again until I made that upgrade!

I’m looking into torque converter upgrades too! I heard that brands like Sonax and Hughes really make a difference in performance. Anyone have experience with these on a 2018 Silverado?

I’ve heard similar things! I installed a Sonax on my '18 Silverado and noticed some serious improvement in torque response. You might need some specialized tools for installation, though.

Honestly, I’ve been contemplating whether to DIY the installation or hire a pro. A friend told me that you can save a lot doing it yourself if you have basic mechanical skills.

It really depends! If you’re confident, go for it! Just make sure to have a good torque wrench handy.

I actually had a pro do it. They recommended a Circle D torque converter, and I’m really happy with how it performs. But they did mention the installation can be tricky if you’re not experienced.

Circle D is a great choice! I think if you follow the installation guide, a DIY could manage, but some might just want the peace of mind from a pro.

Is there a specific model of the Circle D that you went with? I want to make sure whatever I choose has a good reputation for reliability. Also, does anyone know if certain brands work better with stock transmissions?

Good question! I’ve heard that brands like Precision Industries work fine with stock setups, but it’s always good to double-check specs.
