2018 Premier w/transmission issues.

I would take Nick's advice. I personally understand where you are coming from - paid for warranty coverage etc. But if you want longevity see if you can work out paying the difference for an upgraded converter and if they will "flip the pill" on the trans cooling lines.

I've got 100k+ hard miles on my Burb and I fully believe the upgraded converter, the removal of the temp valve, and fluid and filter changes every 25k keep the trans in top shape. Has never had the shutter and there hasn't been a spec of metal in any of my fluid changes.

Sounds like a great truck so best of luck with it.

That's a good idea. I wouldn't mind paying the difference in the upgraded converter. It is a great truck, and we love everything about it.

How many miles did you have before you upgraded the torque converter?

Actually there are no stipulations on where it has to be taken, as long at the warranty work is done by a Chevy dealership. They cover any warranty work as long as your vehicle is in the US or Canada.

Vehicle was paid for with cash, and they have no stipulations on using their financing, either.

I also don't have to have it serviced there. We us an independent shop, and had the 95,000 mile service done at the independent shop. I've already confirmed that the warranty work on the transmission will be covered, once I get it to them on my appointment date.

In terms of them making up the price of the warranty by having a higher price, I just looked up 2018 Premiers with less than 100k within 200 miles of where I am, and I paid less than the price of every one of those vehicles, even the ones that have mileage closer to 100.

I also have several neighbors that have bought used vehicles from the same dealership, and haven't had any issues with getting warranty work done. There is literally no fine print on their warranty agreement. It's pretty straightforward.

They even put it on their website, and it's the same warranty agreement given to the customer and signed by a rep at the dealership:

looks like a decent warranty, there getting it from someone...... does it say who the underwriter is?

I'd have to check to see who the underwriter is.

I'd have to check to see who the underwriter is.

you could probably find out by googling the phone number that you call to file a claim

@NickTransmissions - I was wondering if you could give a quick synopsis on the different improvements from the 6L80 v 6L90 v 8L90 v 10L80/90. Did GM take back steps back as the years went on or there just unique issues with each?

If you had to build your perfect GM vehicle, what mechanics would it have?

I could but it wouldn't be quick or a synopsis, esp if we're talking about the perfect vehicle, haha (ie one that never requires maintenance, always works and makes coffee for you in the AM).

I'm not familiar with the 8 or 10 speeds apart from what we all know about them so can't comment on them too much. Insofar as the six-speeds, the 6L90s are stronger in three key areas: planetary carriers (six-pinion front planetary and wider planetaries in the rear gear set), clutch disc/steel counts (the HD/HP 6L90s have one more friction and steel in each pack) and output shaft (6L80 = 32 splines; 6L90 = 29 splines, large dia shaft or 36 splines).

Hydraulics as well as command and control components are the same between them; things like drums, hubs, shafts, parking rod assy, etc are longer in the 6L90 vs the 6L80 thus not making those parts interchangeable between the two transmissions.

Hope that helps...

It does! Thank you and definitely good info for us all.
Happy New Yr!
