transmission slipped

[Sylvester]

Yesterday I arrived home and drove on my driveway uphill, stopped the truck and put in P. The truck rolled back a little bit and stopped(I know I should have put the parking brake on before that...). I turned it off but noticed I wanted to drive a little more forward. Turned it back on and put the gear in D and as I pushed the gas pedal, the transmission slipped and went to P (or N, don't remember exactly). As mentioned before, my driveway is pretty steep uphill. I saw some warning writing in the dash which included the word "transmission" but pushed too quickly the OK button. I put it back in D and could move on as usual. This was a little concerning. Transmission on a new truck should not be slipping. Is there anybody else who experienced something similar? Any Idea what was going on??

Still kind of confused why you put it in Neutral when you parked instead of Park...

I know the car has some kind of thing when it detects movement after you put the car in park. Mine automatically applied the parking brake once when the car was rolling backwards a little bit. But mine isn't the CVT so not sure how they behave.

Sorry, you are right, was a typo which I corrected in my post. It was P and not N. Mine usually does the uphill support too, but somehow this time it was the transmission which blocked the car from rolling back.

Ah ok, was just wondering about that one. But yah I don't have the CVT so I'm not really sure. It could just have been the computer being kind of confused as to what to do at that moment and hesitating...

I'm a little confused why you're saying it slipped? What you described isn't slipping, but it shifting itself from D to P.

These new vehicles do all kinds of things for our "safety". Since there is no real connection between the shifter and transmission anymore it doesn't need your input to change gear positions. Certain parameters are met and they shift to park.

You should look up a video of the F150s. Under certain criteria the truck will physically move the shifter from whatever gear position you're in to Park. Transmission has already shifted to park electronically, so it just moves the shifter to match that.

I believe if you open the door while in gear, it will automatically go into P. It's to prevent someone form crushing themselves with the door.

It’ll engage the parking brake.

Hi there. Can you send us a DM with your VIN and dealership info? I can look into this for you.

Truck on, in gear, and I opened the door and a warning (gold color border) stating the transmission is in gear. Didn't move forward.

Just remember, this truck doesn't have a clutch. They're not shifting gears. Just when power is supplied or drawn from the two motors or applied by the gas engine.

My driveway is fairly steep going into my garage. I often back out my Prius or the Maverick and park them on the steep driveway in order to get one of my motorcycles out.

I have learned to reduce stress on the transmission (eCVT in both). The Prius really has a hard time getting out of park if under strong forces by the car wanting to roll forward or was parked with forces loading the transmission internal gears that are there

My method is easy to lean and use. I back out of the garage on the sloping driveway. Use the foot brake to hold the Prius/Maverick on the hill. I then apply the parking brake. Next, I put shifter in Neutral and let the weight of the vehicle be held only by the parking brake. Usually, the vehicle will relax and move up or down due to the brakes taking hold. Once the vehicle is supported by the brakes I shift into PARK then shut off the vehicle. At this point I know the eCVT has no forces against the internal parts. To me, over many years, I will have reduced parking stresses on my transmission thereby it should be more reliable. And Yes there are no gears like a manual transmission but there are differential gears inside the ecvt and it does have PARK on the gear selector which triggers something inside the transmission.

It matters not what you think as I will be doing this forever. Try it and see for yourself how Brakes and PARK generate forces on your drive train.

This is the proper way to do it. Only add on would be to turn the wheel so if you ever forget or anything fails the vehicle won't go straight down the hill. But turn and hopefully stop when perpendicular to the slope. Or hits something like a curb, etc.

If I am not mistaken the Toyota eCVT's have a really robust pawl that locates on notches on the outer ring of the planetary gear set to be in "park", and stop the vehicle from moving. I was concerned about my Prius' movement on the drive when parking without the parking brake engaged, until I saw a picture of the pawl. The movement would be the pawl finding it's notch and settling in. Perhaps the Maverick's is the same design (most likely).

Hope the issue you experienced is a design feature as Nick suggested.

Cheers.

Yep Maverick has same design with the parking pawl on the outside of the planetary ring gear.

This is the Rav4 Hybrid but it may be helpful to provide a visual. Ford's HF35/45 does the same thing.

I'm guessing when you go into/out of park on an incline and hear a "GU-CHUNK", it's this metal pawl seating/unseating from a notch under the weight of the truck.
