Drifts forward in reverse up hill

[Michael McDonough]

I have a 2017 Expedition that when put in reverse going up hill will drift forward before I give it gas to move in reverse. This is very unnerving. Any help in what could be the problem?

Could be an issue with the reverse pump. Is it holding in the forward gears? Any slipping or weird shifting going through the 6 speeds?

No slipping in forward gears. Just bought this as a used truck. It is a certified truck from ford. I would think it shouldn’t move when trying to back up even a small hill in reverse. I thought maybe there was something I could change in the setup that would keep it from doing it. I will call the ford dealer about it. I was hoping to keep them out of it but if its bad it should be covered.
Thanks for your help.

Our driveway is fairly steep, if I let off the gas backing up it, it will move down the driveway or forward. It is a heavy vehicle, and the TC is not locked, so if you are idling below the stall point it will move with gravity. Same thing when going forward on a hill, the difference is most modern cars have a built in hill hold that uses the brakes to hold the vehicle from slipping back. Not sure the Expy does, never really paid attention.

Best bet, see if your dealer or someone that has one like yours, will let you try theirs on a hill. If you live on a steep hill, it's probably normal, but try another one and see. I'm sure someone here with same or close vehicle can tell you about theirs. You've got the last year of the 6 speed Transmission.

My 07’ with 6R75 doesn't do that. If I put it in gear (reverse or forward) on a hill it just holds still until I give it some throttle.

Ok, so we got an older 07 that doesn't, and a newer one that does creep. Is this just a newer Expedition thing?

My 17 has a hill hold in forward gears I know. It actually feels like the brakes are applied if you are fast to try and take off from a hill without a big delay going from brake pedal to gas pedal. I’ve never tried it on a hill in reverse. I can let off the brake on a hill in forward gear and it takes about 1 second before it drifts back on it’s own.At the same time if I jump on the gas quick you can also feel a power brake then it jumps.

Thanks for all your help. I`m going to take it back to the dealer and see what they say. To me its a safety problem. I have to back up on my driveway (its on a slight hill)
to hook up a trailer. When I`m doing this I`m not expecting it to move forward before I have to give it some gas. I`ll see what they have to say.

Thanks again

I honestly believe this is normal. Hill Hold does not engage in reverse. If you find out differently, I would be interested.

Yeah I know the older Ford auto Transmissions like the C4,C6,and FMX have a Hill hold only in 2nd gear for some reason. The worst thing about that is they also would start out in 2nd when you went to take off unless you clicked it back in drive or 1st right before taking off. They had nothing to hold in reverse as far as I know.

I think that's just how it works... just like going from reverse to park nose-down on a hill gives a slight lurch forward

PS hold the brake with your other foot

 

[Trainmaster]

I agree; normal operation.

Sounds normal to me. Why would you want the torque converter to engage while at an idle - slipping and building up heat, let alone expect it to hold a heavy truck on a hill???

I have this with my vehicle too. Stopped at a light facing uphill and hill was quite steep. When the light went green and I let go the brake, the truck rolled back until I hit the gas. Scared me a bit and I was lucky no one was behind me. I just learned to goose the gas pedal before fully releasing the brake when on steep inclines.

I started driving with two feet before I obtained my license at 16. Now in my 50's still driving that way. My father drove that way, and my son does too. Left foot always the brake, right the throttle on an automatic. I think if more drove this way there would be less accidents and hitting the gas instead of the brake parking accidents into buildings. Manual clutch left, right brake and throttle. Seems like common sense to me.

I tried the 2 foot method, but it never worked. Mashing on the brake pedal with my weaker left leg, just never felt right. Maybe it had to do with all the years I drove a manual transmission. My left foot was for the clutch pedal. I don't think Ford includes the hill holder for reverse. Don't be surprised if the dealer says it's normal. If you had a manual transmission, you just deal with the rolling, when hooking up a trailer, or backing normally.

Took it to Ford and they also said it’s the way it works. It will hold for 2 seconds after you take your foot off the brake then it will let go. So you should have two seconds to use the gas after you release the brake. Doesn’t seem right to me but that is the way it works. Gotta be quick.

2 Seconds is an eternity in response time or foot movement.
