    Is it a waste of money to upgrade to performance coil packs and wires? Have a 2017 Silverado with 6.2L. Heard some negative reviews about throwing misfire codes. I'm sitting on the fench because of the $1000 my wallet will be lighter as well. Sure they look great but want more than looks

    I installed the Trifecta tune on my 17 6.2L/8 speed and have no issues works as advertised and customer service was great. Not sure why there are some negative comments but to each his own. Would definitely recommend as GM will never fix the issue

    Trifecta has a tune that is around $700 for 6.2L. Does anyone have any information on this other than tech from the company that says significant gains?
  4. High Country 6.2L/8
    Aside from the vast opinions on to have or not. Did anyone install one of the B&M trans sticks on there 8 speed? Have one but didn't install yet

    Your not the only one that has this issue, I'm on my second set and ready for the third and theres only 35,000kms. I'm not hard on brakes but it seems GM cheaped out again. I could get another set under warranty but why bother if they only last for 10,000kms. Anyone have any suggestions on a good rotor that will last?

    Has anyone installed B&M transmission dipstick?
  7. High Country 6.2L/8
    Known or Fluid Film is a popular choice yes. As for what's under mine only the dealer knows lol

    My 17 High Country is rust free and 3 years old, lots of undercoating applied yearly by the dealer as part of the sale. We live in Nova Scotia where any vehicle is bathed in salt

    No it's a pleasure vehicle no towing etc.... thanks
  10. High Country 6.2L/8
    How long ever 3 years regardless of kms?
  11. High Country 6.2L/8
    Would it be overkill to drain coolant/ flush on my 17 at 36,000kms and when would it be a good time? 5/ 150,000 kms seems like way too long.
  12. High Country 6.2L/8
    Dealer done mine the undercoating before it left lot, seems to holding up 3 years and rust free and I live in Nova Scotia a true test.

    Have a 17 High Country it's like brand new underneath
  14. High Country 6.2L/8
    Because someone posted about this additive fixing his 16 Sierra 8 speed shudder on another site. Was just wondering and asking questions
  15. High Country 6.2L/8
    I put Amsoil ATF in my 17 High Country 6.2L last year because of slight vibration/ shudder long before this so called Mobil fix for the issue. Guess what no more issues after Amsoil went in.
  16. High Country 6.2L/8
    Yes, and a follower said that since I was using a Top tier fluid like Amsoil ATF there's no need to use it.
  17. High Country 6.2L/8
    Agreed that flutter is AFM. Delete like I did and have flush replaced with Amsoil ATF and a relearn no more issues and that's a year ago.
  18. High Country 6.2L/8
    Great thank you for your replies ?
  19. High Country 6.2L/8
    I've done the fluid swap a year ago with Amsoil ATF and a relearn and disabled AFM with Range no issues. Was just curious about adding this product yes or no?
  20. High Country 6.2L/8
    Yes Instant Shutter fix sorry I should of explained better
  21. High Country 6.2L/8
    Has anyone ever used this product and if so did it cure the shutter/vibration? Hearing a few people that did and issue gone
  22. High Country 6.2L/8
    I had no issues with rust since the dealer undercoated my 17 High Country from new, they used whatever so called appoved GM product. Well all I can say they didn't miss anything and dealing with salt for almost 3 years in Nova Scotia was a good test. They also installed a rust module some say it's useless but I'll keep doing what's needed to keep it rust free.
  23. High Country 6.2L/8
    Did a AFM delete with Range and the clunking seems to have left for the most part. Dealer is going to do a relearn only a bandaid fix in my opinion. GM needs a software update
  24. High Country 6.2L/8
    Did you try Amsoil ATF? I did swap a year ago through warranty which dealer paid for and no issues since. That Mobil fix is garbage that fluid doesn't hold a candle to Amsoil and the proof is in the pudding with my truck
  25. High Country 6.2L/8
    That's possible everyone has a different story. Have no issues with mine and the dealer does my undercoating since new and let me say this there's not one spot of rust and its 3 years old. The underneath is well protected with whatever so called GM approved stuff it is I'm not sure. Nova Scotia has some of the worst salt roads that will ruin a vehicle in a hurry if not mantained.
