Hate to admit - and I’ve not yet admitted on this forum - my Sierra is now a 2018 Honda Pilot Touring AWD.   I’m now a 140-mile/day commuter and when I bought my truck, I wasn’t.  

 

The calc was twofold.  Highway MPG has increased 40% and the depreciation schedule extended an unknown but certainly tremendous amount.  

 

My wife drives a 4Runner.   We still have a truck in the family.   

You might have jumped out of the frying pan into the fire. The Pilots 9 speed ZF transmission is notoriously worse than GM’s transmission. My wife has a 2017 Pilot Elite we purchased new. 15,000 miles later and she has already had the transmission replaced. Service manager said they have replaced several. Don’t google Honda Pilot 9 speed transmission if you have high blood pressure.

I had my TC replaced at the end of June and all my shuttering, vibration and clunking is gone. Since then I have driven from FL to MI and all over. Put on a lot of miles and it drives smoother than

Yea, I’ve read most of the reviews of the 9 speed.    I only have 1500 miles on the Pilot but the very seldom less-than-perfect shifts to date have been minor.  Certainly I have been battle toughened by my good looking Sierra’s transmission!

 

I do see Honda has made some programming mods to the 2019.   

 

At at least Honda didn’t say “operating within normal parameters” and send you on your way.   Do y’all like the vehicle?

Honestly other than the transmission issues we love it. We have two daughters that play college lacrosse. The Pilot is what we use to travel around to all their games and tournaments. We had the dealer install the tow package when we purchased it, amazingly it pulls my 4000+ boat around town better than you would expect. Wife will likely get another in a few years when their new 10 speed makes it into them. Heard much better things about that transmission so far.

Thanks.  I hope my transmission holds.   

 

Another thing i find interesting:  I also have two daughters in school, one at Ole Miss the other as a D1 (first year dental school).   4 hours and 2 hours away.   That’s not THE commute, but it’s A commute.  One less frequent, but more fun!

 

Godspeed!

Update again:

Next visit to the dealership to do the triple flush on the shuddering transmission. while I was in the lobby waiting (only a few minutes) reading my lemon law book; the service manager came out and said it looks like we have an update on fixing your transmission. now GM is saying go ahead and skip the triple flush and replace the torque converter. well well, that's what I asked about to begin with if they knew it would fix it, why not!? so  they kept it about a week to replace the torque converter. I've driven it about 700 miles so far and it is very smooth, no shaking or shuddering so far. the thing that worries me is how much damage did it do to the rest of the transmission driving it with the wrong fluid in it and the torque converter going out (metal shavings pumped throughout the transmission) what is going to happen say 50,000 miles down the road? this was to be my last new truck since I am retired and on a fixed budget. I won't have the money to pay for replacing a transmission... concerned, don’t know what I should do even if it seems like it's fixed?

Whats your update since you had this done? I've gotten the triple flush with the new synthetic Mobil 1 fluid, but no torque converter or valve body replacement.

Jdub289f, I have had the fluid flushed, torque converter replaced (back in '18) & had the "new" fluid flush done this past February.  That flush worked great for about 200 miles.  It didn't shudder, it shifted when I thought it should have, but after 200 miles it was back to the same ole thing, actually worse now that it was before last flush.

I had the flush done as well in feb I have a 18 with the 8 speed. Truck is back at the dealer today because after about a 1000 miles it’s acting up again. Service guy said next step is throttle body and torque converter. Amazing you gotta take a wrench to a truck this new.

Here is another one.  2017 6.2/8 speed.

At 25,000 miles replaced torque converter.

Now at 56,000 miles it started shuttering again.

Yesterday they replaced ATF with a "machine they got from GM".

Today doing much better.

We will see how it does over the next several thousand miles

      Replacing 2.7L on 2021 Silverado with 2023 2.7L

      I’m definitely interested to hear the end result here.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
