Anyone pay for a "preventative" 8L45 flush?
I know this sounds crazy, but hear me out.
I bought a 2018 WT V6 4wd, build month 4/18, in Sept of last year. Then I got on this site to learn about my new acquisition and discovered to my horror that the transmission may be a ticking time bomb. Your eyes can go numb trying to review all the posts on this issue but I've read of some 17s that have made it nearly 20k miles before the shudder showed up and now the 2019s are having the issue, one with less than 1000 miles. My truck has 4k on it and no evidence so far of any shudder, clunk, or thud.
So, do I live with this uncertainty and the possibility of the following complications?
>Lack of confidence in my truck,
>Possibility that the shudder could start while I'm on a long trip,
>Possibility of torque converter clutch damage by the time I get to the dealer to have the fluid flush,
>Loss of my time while I deal with the problem - I doubt I'll be able to drive it into the dealer's and have it fixed that day. Also, my closest dealer is 1/2 hour away. If the TCC is damaged and the flush doesn't fix it then there are a couple of more trips.
When it comes to the last point, what's your time worth, particularly if you have to take time off work to deal with this problem?
Another thing to consider is that I'll own this truck for a loooooong time. I don't have the resources to pop into a new vehicle every few years. I sold a 2005 Ranger with 168,000 miles on it to buy this truck.
I'm going to continue to monitor the last pages in "shudder threads" (as many as I can stand) to see if this latest trans fluid fixes the problem in the womb, so to speak, on current production Colorados. It could take a while to see any effect if GM is running out their supply of the previous fluid to save having to toss however many thousands of $$ of it they may have in inventory.
BTW, it would sure help if people would include their build date (on the driver's door frame sticker) when they post about this issue. And, obviously, the mileage that the shudder first occurred, as I've seen a few posters omit even that basic piece of information.
So, is paying for a "preventative" flush out of your own pocket terminally stupid, or perhaps a reasonable (although somewhat costly) way to avoid the problems listed above?
