Transmission shifting roughly

[majorranger]

I have a 2019 Ranger and since it has been pretty cold lately (low 20s), it is shifting rough at low speeds from 2nd to 3rd gears. Is there something I should have checked or updated?

reset the adaptive learning memory for the transmission first, then check the transmission fluid second and see what it does

Let the engine idle until the RPMs drop. That's all my local dealer would say and I do not have the issue if I let it idle until RPMs drop under 1,000. Yes, it's really annoying when you're just making a local trip.

Mine too lately, well since we have been staying below freezing, only till it warms up then its fine the rest of the day, I always remote start and idle my truck in the winter ...

My 1-2 shift can be rough, but I have been using tow mode more this winter than last. The 1-3 shift in drive is usually much better. It only does it the first shift then no more till the next morning.

Mine's shifting rough at higher speeds, when it downshifts from 10th to 9th & 8th. New DPFE didn't help. .

When it’s cold I let it warm up at idle a while.

As do I. But usually not more than 5 minutes.

Don't do this unless you're willing to do the proper relearn.

The Adaptive Learning Drive Cycle must be performed after any of the following procedures are performed:

• Transmission rebuild or replaced
• TCM replaced or reprogrammed
• Major engine work performed
• Air/fuel management adaptive values reset

Perform the adaptive learning drive cycle on a level road surface as follows:

1. Record, and then clear any DTC’s
2. Drive the vehicle until the engine and transmission reach normal operating temperature.
3. Accelerate from a stop with light throttle (15%), ensuring that upshifts 1st through 8th occur at engine speeds between 1300-1600 rpm.
4. Continue to accelerate (may apply slightly more throttle after 7-8 upshift at 32-38 mph (51-61 km/h) until you achieve 55 mph (88 km/h) and the 8-9 and 9-10 shifts complete.
5. Brake very gently to a complete stop and hold the foot brake for five (5) seconds.
6. Shift the transmission to Neutral. Wait 1 second.
7. Shift the transmission to Reverse. Wait 2 seconds.
8. Shift the transmission to Neutral. Wait 1 second.
9. Shift the transmission to Drive. Wait 2 seconds.
10. Repeat Steps 3 through 9 six (6) additional times.

After the final step, place the vehicle in park and cycle the ignition key off. Wait 3-5 minutes before driving.


Personally I wouldn't.

How many miles on the 2019?

When the box is cold, the fluid is very slightly thicker than optimal and you can have some rough shifts at first. It isn't necessarily a problem, but it is annoying. If it hasn't been done, a fluid service can pay off, as well as using 12-15oz of Lubegard Platinum.

There are several users here that have reported good results with this. @TJC is one.

really? i'm curious why. i always warm my ranger up whether it's warm or cold outside. the transmission just doesn't like cold temp fluid. during the summer the warmup is 1 or 2 minutes, but during the winter i'll leave that em effer out there like 10+ min lol.

admittedly it's mostly cuz i'm a pansy about the cab not being warmed up. i like comfort when possible. but also the transmission behaves better.

Not just the Tranny, Im thinking the Turbo too....
It was -6F leaving this morning and probably wont go above 32F till March

It's just what I do. A long warm up isn't required and I don't like wasting fuel.

I have always from day one let mine run till it idles down. The colder it is the slower I drive off to warm it up. Always tow mode.

Thermal camera of Dash, its hot before I hit the end of the driveway, even if I only idle it a Min.
after these pictures I figured out in the settings how to change it to F LOL
Its the goyojo its not as clear as I want

I've been doing this my whole life going back to the days of 4bl carbs. Start it and listen for the rpms to drop then go. Summers are usually 1-3 minutes but winters (especially in MA & AR) could be as long as 15 minutes. I'd rather waste a little gas than damage something internally not letting it warm up and having the oil flowing good.
