Ditto.  8-sp, 5.3 late model 2019.  No issues with trans other than a few hard 1-2 shift on cold Canadian mornings.  But a remote start warm up eliminates it.  Only 4 months old, so anything can go wrong, at any time, I guess.

I like my 10 speed. I do wish the performance mode would firm up the shifts some. I am used to tuned transmissions that have a firmer shift. Just a personal preference. I wonder if a zl1 shifts the same way or if its firmer?

Mode in mine firms the shifts

There are two different TSBs for the shift programming on the Ford version. While they are the same transmission mechanically, the electronic controls for either version are exclusive to each manufacturer, and each version is built in their own plants. For that reason you really can’t lump Ford’s problems into the GM version.
 
Mine has been totally flawless. Reports of ANY issues or complaints with the GM 10 speed have been so scarce to the point of being meaningless, isolated incidents. Unfortunate, but it can happen to anything.


A colleague of mine is going to the plant in Toledo next week [emoji16]

Ive notice if i put my 19 LT TB 5.3 8spd in Auto instead of 2wd the 1-2 shifts are better and the DFM activates less. Down side gas mileage seems to go down a little.  But back on topic I wish my tranny would just stop working, maybe then i can get something fixed.

Valve body replaced, which included the solenoid that was bad ( reported by TCM).  The truck now shifts.  I will update should anything else warrant it.

Over a month in, nearly another 1900 miles.  I believe I have 3-400 more to go before the same mileage when the valve body failed previously (1939).  Crossing my fingers it makes it past that.

Same, my 8 spd, first 1-2 hard or hanging shift, won't happen if I warm a few minutes.....once the tranny fluid is above 90-100F shifts smooth as silk. Post 3/19  doorplate sticker production trannys have factory fill Mobil1 fluid and tech bulletin advises 122F for proper test operation of tranny with this fluid.

      Oil Consumption

      By Chuck FB · Posted

      Ok that confirms the extra quart theme they are still going with which must mean they have noted some initial use more so then some engines and probably the bigger factor in all of this probably isn't the engine so much as its the insane distance or OLM that lulls a lot of the driving public into driving their new vehicle off the lot and not even doing one short interval oil change because the manufacturer doesn't say different and if the dealer follows that logic as well. Selling the rarely needing to be serviced concept seems to go over well with the public that wants to get away with as little as possible for dollars spent on the vehicles maintenance and I bet there are 3.0 engines just like other vehicles out there that never have their oil checked by the owner which goes back to why they probably felt the need to add that extra quart to avoid a costly theme.    Speaking of cutting filters open, it was probably over two years ago now that a youtuber who buys vehicles to do longer term reviews and pulls a fifth wheel through the mountains of Colorado on summer trips and that becomes part of the testing. Anyway he had a GM HD with the 6.6 gas and a Ford 250 with the 7.3 gas at the same time and of no surprise the Ford had more power etc but somewhere along the way in the few thousand miles he put on the truck, he changed the oil and was seeing glitter and cut open the filter and yeah, things were not looking spectacular. The truck about that time or soon after seemed down on power compared to what it had been and then threw some engine code, I expect the cam/lifters were failing and so he brought the truck back to the dealer and made some deal to get out of it as he knew it would sit for months waiting on a new engine as they were so backlogged at the time. He kept the GM for some time after that using it exclusively until he sold it after buying his next vehicle to do a review on. Definitely the filter can tell a story when things are starting to go sideways, but it would be a sickening feeling to cut it open and be faced with an ugly mess like that and be running a magnet through the pleats and the oil on the dirty side of the filter and see all the fines sticking to the magnet.    The dealer may have some ideas based on experience as to where that coolant smell is coming from, I would imagine if they can't find it but its smelling they would put dye in it to they could give it a run cycle and use the black light to see where it pops up, if its a hose connection, water pump, rad or even a head gasket etc.

      charm.li (website) has the vehicle-specific diagnostic procedure for that code, you can use to find what the cause of it is.

      Oil Consumption

      By KARNUT · Posted

      It’s at the point of amusement. I’m retired I have time. It’s fun seeing people try to convince me I’m using oil. I’m buying oil at the prescribed time. It gets drained and new goes in. Do I add in between, no. My oil doesn’t even get dirty in 5k miles. I don’t even see any drop on the stick. I check in the same place. All is well.
