1-2 Shift lag/slip

When leaving my house, in the morning, I accelerate slowly. My truck shifts out of 1st and pauses before going into second.

The momentum of the truck slows and when it shifts into 2nd, it jerks.

It's uncomfortable but I also wouldn't want to be in the middle of that when I am required to accelerate quickly.

Does anyone else experience this?

Re: 1-2 Shift lag/slip

There are a couple of threads of transmission troubles on the 2014/2015 Jeep SRT's. I hope yours isn't one of them. Search for these threads on transmissions. You'll find them.
Good luck!

Re: 1-2 Shift lag/slip

I've seen threads about higher gears. Just haven't seen anyone specifically talk about the 1-2 slow shift.

Re: 1-2 Shift lag/slip

Maybe you need the newest update to your transmission. I think that one came out a week or 2 ago.
Good luck and let us know how you make out.

Re: 1-2 Shift lag/slip

Mine does the same thing and it is only the very first shift since being parked. I asked before and didn't get many responses. I also have an occasional 6-5 jerk when in auto and a 4-5 slip in Sport. I plan to take it in for the new flash at some point when I get some free time.

1-2 Shift lag/slip

My '15 does this as well. Also just in the first shift since being parked for extended time. I also have the occasional 6-5 jerk during hard braking. I'm hopeful the new tranny flash fixes both.

Re: 1-2 Shift lag/slip

Happens to me as well and every time wife says I can't drive.... Pisses me off . Very annoying although it is random or at least I haven't figured out what causes it.

Re: 1-2 Shift lag/slip

I'm dropping mine off in the morning for the newest PCM flash...we'll see if it helps this issue, along with a 4-5 slip in Sport and 6-5 "hard lurch" in Auto.

Re: 1-2 Shift lag/slip

The most recent transmission flash seems to have fixed the 1-2 shift lag...*knocks on wood*
