Shifting Reverse to Drive lurch

[dcgibs]

I was just testing right now, again after work.
I do reverse backup, stop, shift to drive and get on gas right away. Truck actually starts to roll back, w/o power. Then a 1-2 seconds latter kicks forward.
After going forward I stopped, shift to reverse and get on gas right away. Truck does opposite, start to roll forward, w/o power. Then 1-2 seconds kicks into reverse.

I’ve never in my life experience this reaction to shifting, even getting on the gas quickly after.

I am convinced there is something wrong.

@P. A. Schilke what is your suggestion? Dealership or should I call Ford, is that an option?

Hi,

Time to get a Ford Field Service Engineer involved if the dealer will not to a Test Drive....You have to be forceful for this to happen. A call to Ford Customer Service should also be done...Something appears wrong to me...

Best,

i know this is old thread but its new to me since im kinda new. my truck does this once in a while also. mine is 4x4. i always stop fully before changing between R and D. when the truck is warm and ive been driving for a bit it will not do it. if i just start it up after its been sitting, then it happens. of the five or six times its happened one time really had a good thud, you could feel it shake the truck. took it to my friend that is a ASE mechanic that day he put it on the lift and looked around, pushed and pulled on the driveshaft etc. and said things looked fine. that makes me think that the unwinding or winding Phil mentioned earlier in the thread may be what mine is doing.

I’m curious if your friend also checked the transmission fluid level?

good thought, he did not check it. honestly i haven even checked it myself in about 3 months... think maybe its a fluid level issue?

Not if you checked it 3 months ago and there are no leaks. Not sure about the Ranger transmission but previous automatics I had would be sluggish to go into gear if the fluid was low.

I've experienced this phenomena a couple of times when my truck is cold...what happened during these rare incidents is that the transmission delayed engagement when I shift into reverse to back out of garage...so after shifting, I let off the brake, then 1.5-2 seconds later the trans engages reverse when I had already lifted off the brake...so there's an unexpected lurch...just needed to hold the brakes a little longer...

I believe Mark is a newer Ranger owner. I think he meant that he hasn't checked it in his 3 months of ownership.


Mark, many Rangers were undefilled from the factory. Might want to check it. It's a pain to access and right near the hot exhaust.

Crack it open first to break it open, cold truck, close it up gingerly. Go for a drive and check fluid levels afterwards when warm. I use a Kevlar glove and sleeve to protect me, but whatever you do watch out for the hot exhaust.

What? Are you saying we can’t pull a “Rockford” in our trucks?

I hadn't heard the term "Rockford" before. But immediately I figured you were talking about J-turns. A quick Google search confirmed!



Our milktrucks that have Allison transmissions employ a shift inhibit feature to protect them from these types of shenanigans. The ones that don't, well, they have no protection from hoonigan milkmen.

same here, i also experience it on my new 21 Explorer 2.3 10 spd but only when its cold shifting for the first time in the day.

That was a lot of fun to do in my beater when I was young...I'd never try that now with my own cars ... ?

thanks folks!
ahh yes the rockford! i had to do at least one in my last mustang before selling her, took a couple attempts to get it satisfactory. the last one with 20 feet of elevens was just to be a perfectionist. likely wasnt good for the clutch or tires. wouldnt let me into first without being basically fully stopped. 2nd worked, just added more rpm.

Most manuals gate the 1st gear so that it cannot be shifted into above a certain speed.

A proper rev match with a double clutch will often defeat this. Allowing you to downshift into first at the higher part of it's range effectively.
