Transmission issue suggestion

[Illking]

Hey gang, Ive been reading lots on this topic here at 5g and to be honest its a bit overwhelming so I humbly come to you for suggestions. My truck is about 47k maintained well and dealership did transmission fluid around 43k. It has just recently started a new strange behavior. I live at the top of a hill, I drive down it to flat road, when i go to accelerate on flat road i totally lose power momentarily sometimes 2-5 secs of it just feeling like it slipped into neutral (quite scary when traffic is coming). other than that I haven't had any transmission issues besides maybe a handful of random hard shift but nothing consistent enough to be concerning. My truck has been running a livernoise performance tune for about 5 months and it has really cleaned up the shift points besides this neutral stalling issue. Seems to have started just when I made my final payment and received the title

Before I run to the Dealer which I will since I am still under factory powertrain warrantee, is there anything I should do / can do without forescan. TCM relearn seems to be a suggestion after services, tunes etc.

80% of my driving is in heavy stop and go Los Angeles traffic and some hills so I think moving forward ill utilize tow mode more and or disable AutoStart/stop.

Thanks and sorry for another transmission thread I promise to make it up to yall by posting pictures and trip report of my trip to the sierras this weekend.

Jason are you an early 2022 truck? If so you may have the dreaded CDF issue and want to have it tested while under warranty. They will charge a diagnostic fee but if it is the old style CDF drum, it will fail and be covered.

I ran the Livernois tune for 6 years on my 2019 but set the truck back to stock a couple months before bringing in for testing. I told the service writer it would fail and was right even though neutral out for me happened only once or twice. Hard shifting like you are experiencing didn't happen enough to bother me either but to me were signs my CDF would fail the test.

Good luck on whatever you decide.

Since you recently had the dealer change the transmission fluid, I would suspect a low transmission fluid level. Check the transmission fluid level.

Yes it is a 2022. Thanks guys, I really appreciate it. I'm almost due for another oil service so Ill schedule that and the CDF diagnostic but first ill check my transmission fluid to be sure.
