Air vents fall down and transmission slams in to gear

scokill · August 14, 2020

So I have two issues. The first might seem simple, but it's maddening. After about 15 minutes of the air conditioning being on, I have two vents that loosen and fall down closing the vent. Warm truck fine, as their AC cools the plastic the vent falls. The dealer is ordering new vents...just wondering if anybody else has the same problem.

Also I've had the software update that supposedly fixes the gear shifting issues. I have no issues other than when I'm first taking off, and especially shifting from reverse in to drive. It's very sporadic, but it will slam in to gear and I've had times where people turned around and thought I hit something. Other than this the transmission shifts very smooth and drives like a dream. Of course they've checked it out and didn't find any issues. Anybody else have this problem and has it been fixed and what was done?

At least one of my vents also falls down by itself. Irritating for sure, and I hope to find a way to fix it.

Yep same problem with transmission. Going from reverse to drive What a bang. I found you have to move shift lever slowly it works fine. Once in awhile I do feel the trany searching for a gear around corners.
But my vents didn’t move!!

Wow, i have not seen this issue since the 1980's when the plastic used for the vents was about as cheap and as brittle thin as possible.

I have the slamming tranny. It has done it about 6 times. Always when slowing to take a right turn. Scares the crap out of me. The engine is so quiet I don't realize it's reving then bam. I immediately called the dealer the first 4 times so it was on record. This over 16 months. My 10 speed isn't as smooth after 30k miles but it hasn't been back to the dealer once. Finally getting all the recalls next week.

Change your reverse to drive shifting habit:

20-NA-102: Lack of Acceleration Followed by a Clunk Feeling After Shifting From Reverse to Drive - (May 14, 2020)

Some customers may comment that after traveling in reverse and shifting the transmission to drive, the vehicle may experience a lack of acceleration followed by a clunk or harsh downshift feeling.

This condition may be caused by the fact the vehicle not coming to a complete stop before shifting from reverse to drive.

If the transmission output speed (OSS) of the transmission does not obtain 0 mph/(kph) before shifting from reverse to drive, the transmission will be commanded to start in 2nd gear. Upon increasing the throttle, the transmission will command a 2-1 downshift, which will be harsh.

The OSS may appear to obtain 0 mph/(kph) when reviewing GDS data. However, the filtered signal as determined by the Transmission Control Module (TCM), may be above the 0 mph/(kph) threshold required by the TCM.

The vehicle must come to a complete stop prior to shifting the transmission from reverse to drive.

Important: Replacing components on the transmission will not provide a resolution to the customers concern.

The information found in this bulletin can be shared with customers that may inquire about this condition.
