Transmission Behavior when Cold -

[BAQ717]

Anyone else’s transmission torque converter seem to “slip” on the first gear change when cold? It’ll change gears fine but then RPMs will dip soon after under throttle. Goes away after doing it once or twice. No issues other than that, transmission is quick and smooth. I am assuming this is normal behavior but wanted to get thoughts. My truck is not in the recall and I don’t suspect anything serious but still worth asking

Yep, mine does this every day when cold. I'm in the TSB range, but from what I've seen this is pretty normal.

Mine does the same thing on the first shift. I live in Florida and even on a warm night the first shift is rough. I have gotten into the habit of taking it easy through the first shit then driving regularly. When at out PA home on a cold night it is only slightly worse, but not something I would consider an issue. I guess like my 64 year old joints, takes a few minutes to get the fluid moving.

Mine does this too. 100%. 2025 TRD OR purchased in mid-February.

Mine does this too after a cold start, usually the first shift off the driveway

I’ve had my 2024 for a year now. It is slightly better now since I got my truck OTT tuned.

In addition to mind like others smoother when warm, my experience with other makers' 8-10 speed automatics seems quite the same. For examples, the Acura car and GM I think Allison automatics in heavy duty pickups.

I agree @bitflogger, lots of 8/10 speed automatics have similar problems. Mine had some odd shifts and a few scary reverse engagements when it was below 1k miles, but now it is mostly fine. I have no idea what changed but as long as it stays the way it is I am a happy camper.

More and more I start to wonder if my age is showing not being reactionary like many, but for how many don't know how good modern vehicles are.
