So my new to me 2014 Silverado with 95,000 miles just lost its transmission in the first week of me owning it.
In calling around to local transmission shops the general consensus is that these transmissions will only reasonably last 80 to 100 thousand miles without either the pump or torque converter going out.
Anybody have any thoughts or similar findings?
Hey guys, I want to work on my truck and upgrade it but i dont know what i should do. What are some things you have done to your engine and drive train to enhance performance and add durability?

So when the truck was newer I used 4x4 a few times and it would make almost a metallic grinding noise when turning. I took it into the dealership multiple times trying to get a fix and they kept saying there was no fix. So be it. It works still even with the noise. This truck was always maintained by the dealership until 80k miles. At 72kmiles the check engine light came on almost out of no where and I took it to the dealership to find out the injectors were bad! What the heck! Then andother 8k later the rear differential started leaking oil and I had to replace that. That was fun 4K into a 2015 truck in the same year in repairs that shouldn’t have happened that early in the trucks life. Thennnnnnnnn at 104k the transmission went out!!!! What in the heck! All of these repairs were done in a 9 month period. 10k into a 4 year old truck. I’m very disappointed in this truck. I always kept up on oil changes and most maintenance. I did not flush the transmission at 60 but that still should not have put my transmission out at 100k. I have towed about 4K max behind this truck less then 8 times for no more then a total of 200 miles so I’m not rough on the transmission. I’ve also only had it off-road 1x early on in its life so definitely not had a rough life. Almost 60% of the miles are freeway miles. These problems should not be happening to a Chevy truck. I’m really disappointed. All my ford friends have given me so much Crapp and honestly, I may as well have bought a cheaper not as well designed truck and saved myself about 10-15% on the ford truck.
Not sure if there’s any possibility of gettting any of that 10k covered from Chevy but that would really make me think a lot higher of the brand.
This is my video of MODEST upgrades for the L86. I'm new to posting as well as video blogging so I apologize for the quality and such. I'd like to start making some videos on HOW TO's for this particular engine. I've done almost everything to this thing in my driveway. so to the weekend/garage warriors who want more let me know what you want to see and I will build a video and post it. Bolt on's or porting, oil changes w/e let me know.
I just bought a 1991 Chevy C70 Kodiak C7H042 6.6L 403 CUI Diesel in amazingly great condition. I am now the 3rd owner of this dump truck. The first owner took great care of the vehicle, everything thing appears to be well maintained and no shade tree work. All the parts, wiring and accessories appear to be original and well maintained. However, the second owner bought this truck and never used it. It has sat in a field for about four years. To get to the point, I completely serviced the truck and replaced the batteries, checked the fuses, grounds, relays and I have absolutely no power to the truck. No interior or exterior lights and no lights on the instrument panel. What could be the issue?
