Transmission 8 speed. 1st gear seems to hold long before it shifts up. Or it seems a little long to me. Been like this since I bought the truck. Is this normal? I had a 12 Ram with the 6 speed transmission, don’t remember that one doing the same.
Thanks!

Number one cause of delayed shifting is trans fluid level, which is a problem with the 8 speed to check level. It is likely due for a drain and fill with filters, see if that fixes it.

The 8 speed has a very specific procedure to fill and check fluid level, there are copious posts on this site of the green sheet instructions (thank you, Rick, AKA @Wild one).

Follow them.

Please post with any questions about the process.

Does this primarily happen on the first upshift out of first for the day? This is somewhat a phenomenon with these transmissions, some seem to do it more noticable than others, the other mentioned quirk is the transmission will flare out shifts(2-3, 3-4) and people will ask if it's starting to slip

My 1500 used to flare on the first shift of the day, otherwise the transmission acted like it couldn't get out of first gear fast enough. I believe letting it idle in neutral for a minute flows fluid through the transmission where park does not and helps eliminate this issue. OP should definitely still check his fluid level and probably change fluid though.

Idling doesn't help in my case, I back out of my garage about 150' and still get the delayed first shift from time to time.

Our 2019 Classic will sometimes do the sluggish 1-2 shift on the first shift of the day, when everything is cold. I believe that's just normal operation when it hasn't warmed up yet. We typically drive pretty easy headed out of the neighborhood anyways, one neighbor has a flock of "free range" chickens that love to dart into the road at random times.

This transmission is used in numerous high end cars, BMW, Land Rover, Aston Martin, even the new Supra. If there were major problems with it you'd have heard about them. Don't romp on it until the fluid has had a chance to circulate some, it will be fine.

That's a bit of a leftover theory from the RFE trans wherein the trans cooler circuit did not flow in park and they were notorious for drain back in the cooler circuit so idle in neutral helped them out.

Good to know. Must have been a coincidence when it decided not to flare then. I haven't noticed it on my PW so I wonder if they updated something on the 75s.

Don't know if my 2016, 8 speed is the same as yours, but I noticed slight slipping 1-2 at 20,000 especially when cold.
I watched it until 59,000 with slightly more slipping. Finally I got an occasional flashing P from the shift indicator.
Fca refused to help repeatedly, but finally they got some kind of clutch error code, and I got a new tranny.
You have to be very, very persistent.
