Bought a 2016 White Denali 3500 in October 2015 (one in the first batch) (D-MAX with Allison Trans)

 

The truck has been FLAWLESS... minor things like the right mirror LED blinkers are SO DAMN bright at night it's blinding... and my phone will not charge on the wireless charger (the light comes on and 5 seconds shuts off...

 

whatever i can live with those...

 

UNTIL this Monday after sitting in the garage for 3 days i pull it out and 2 nice large puddles under the front of the truck... i think water??? but i have not moved it, and no snow (live in Michigan) like ummm... look at it OIL? or TRANS? and yup red trans fluid... get under the truck and it's all over the front of the trans...

 

only has 3200 miles on it... and i have yet to tow my trailer with it... so i know it has not been pushed at all... i always warm up the Diesel before driving and so I have no idea.. taking to dealer tomorrow.

 

ALSO going to have them fix the BRAKE pedal recall and any recalls too... since they will have it to find the leak... (never leaked till this Monday)

 

again minus this it's been perfect...

 

 

I will post after i get back solution they came up with and performed to fix the leak.

My 2015 had a transmission leak, my paperwork says - PIE0319 Fluid Leak from Front End of Allison Transmission.

 

 

For the wireless charging, it only works on certain phones. If you have an iPhone, then you will need a certain wireless battery pack for it.

 

The mirror, can't help on that one since my windows are tinted.

Your HD truck fits in the garage? One lucky guy I'll say! Long bed?

So the Dealer called me today... apparently the Torque converter is leaking inside the trans housing. I will get the truck back tomorrow and will post all the details

they also are doing ALL and ANY RECALLS and any firmware upgrades (I asked for them all to be done)

 

truck fits in garage nooo problem. i have CREW with STD BOX and i have a SUPER DEEP 2.5 car garage..i have about 2 feet in front and 18" behind it with door closed.

 

on wireless i have a NOTE 5 that supports BOTH wireless charging standards. and like i said it starts but then after 3-5 seconds it stops... not that i care i just use a USB cable. (I'm an IT consultant) I got the tech crap nailed down... just don't know why it goes off... like i said not anything to worry about, if it works great if not don't care... i didn't buy this thing for that... just a perk... i bought it to haul my race car.

I noticed my oil pan gasket was shot and leaking around 10k miles.. Common on LMLs from what I've heard and seen.

 

Sounds like your issue was just a freak thing. as long as they cover it under warranty!

      Most say the oil temperature needs to above the boiling point of water to rid it of moisture and long enough to dry it. Many think that is about a hour at 212 F or more. Those people have never line dried cloths in a Midwest winter. Leave a pan of water sitting on the counter and eventually it all evaporates. So heat drives the time it takes. Water in oil under 175 F, the Nitration initiation temperature, is a minimum then for temperature and samples I've done that use Karl Fisher method say about a hour (in a healthy well tuned motor) over 175 F will dry it to under 800 ppm. Low enough to not be much of a factor. Motors with weak rings will take longer and the colder the air temperature the longer it takes.   On a cold motor there is also the condensation temperature. Blowby gases that contain moisture are subject to that cold cylinder wall, like sweat on a glass of ice tea. But also subject to the Law of Partial Pressures. Wear studies by GM and the DOD  indicate wear is a real issue below 85 F and a concern to 140 F but doesn't become a minimal factor until about 160 F. You know this intuitively when you see water vapor exit the exhaust pipe until the system gets above the dew point. It isn't magic, it's physics and it fascinates me. I know you didn't ask but....I over share sometimes. 😉    You keep the Camaro's high and tight.

      Move further away.   Benefit of living out - none of our cars get short cycled, plenty of warm up time.   Curious how much time/temperature it takes to drive moisture/condensation out of the engine?

      Transmission Temperature Hitting 220s

      Switch a a 100% synthetic trans fluid, Amsoil works for me.

      Transmission Temperature Hitting 220s

      By DustMcGrath · Posted

      First of all sorry, I know there are a ton of transmission temperature threads...   My truck is a 2025 LZ0 High (10l89 10-speed) High Country with NHT max trailering package. The NHT package is supposed to have "enhanced cooling."   Normally the trans temp sits around 200. It seems like with any real stress it quickly jumps into the 220s (for example climbing a grade unloaded at lower speeds). I haven't towed much with this truck, but I'm concerned if it gets this hot unloaded.    I've tried a few different things to keep the temps down (tow/haul mode, sport mode, low range when that makes sense) and nothing seems to affect it.    I'm curious if others are the same behavior or if anyone has found techniques to keep the temps down. It seems like it just can't handle reduced airflow at lower speeds, even with relatively light loading.    Thanks!

      I'm at 105,000 miles on my baby Duramax. No issues yet. I hit 31 mpg's traveling through hilly terrain to a project in Colorado. I will buy another 3.0. I'm not concerned.
