2021 Gen3 Transmission issue???

[RaptorCDH]

Hey Everybody,

So my 2021 Gen 3 with @4k miles has had perfect shifting ansd excellent transmission performance.

Today while coasting with a bit of light throttle …a sudden loud noise and a jolt went through the driveline. I thought someone hit me from behind.

It has never done this until today. No error codes and transmission and it didn’t seem affected after the remaining drive home.
Shifts were smooth as ever …
I’m hoping it was a one and done occurrence…. We will see

Cheers.

if you apply throttle mid downshift, you will be rewarded with an “inarticulate shift”. This happened on my ’17 once and I was of course a little concerned. However, like you it resumed normal operation. On a bet, I decided to try and replicate. It took a while, you have to catch the truck in either mid up shift or mid downshift at just the right moment and give a bit of throttle and ‘clunk’.

They can’t program for everything.

Hopefully it was a one time hic cup! Must of caught mid shift. I think the Gen 3s are built pretty tough !

Yes. The transmission has been perfect on my rig!!

Downshifts in D when in sport mode can be pretty violent. I can feel the driveline move.
Worst case scenario, it’s under warranty…

Firm shifts in Sport mode are by intent. If it shifts smoothly in normal mode, there is not a hardware issue present.

Totally my understanding. Thank you

Agreee …Sport does have firm shifts for sure. I was in normal mode at the time…this particular shift was loud and pretty violent—it felt like someone hit back of my truck …my gen 2 did some occasional missed shifts (ie noisy shifts that either missed a gear or made a loud metallic driveline shudder / noise…)

This was much worse…either way stuff happens and it is warrantied so I’ll just keep on driving!!!

I know exactly what you're saying as my 2019 has done this twice after driving spiritedly and transmission temperature was around 240°.

Getting on the highway and while shifting, it was extremely violent as it felt as though the transmission was coming through the floorboard. This was after a brand new transmission was installed. I took it in and Dealership stated it was overfilled. It's done it one more time under the same circumstances.

Afterwards it goes back to shifting like butter.

why was your trans replaced? also 240 sounds high
