Weird Nuetral Behavior

Recommended Posts

I've had my 2015 Connect XL for a week (75k miles) and it's acting extremely weird. I was getting off a highway ramp and put it in neutral and revved it up and as the motor spins down it tries to engage the gear and surge forward like the transmission isn't fully out of gear when you manually put it in neutral. If you're at a stand still and rev the engine it does the same thing. I've never seen an automatic vehicle behave like that. I have read some negative reviews on the transmissions and after seeing the van do this I'm wondering what causes them to fail. I know earlier models were worse but is it a heat problem (possible fix by adding a tranny cooler?), or maybe a mechanical issue? Has anyone else had a connect tranny do this? I have a short warranty so if this is a sign of a weak tranny I want to know so I can diagnose and bring it up before my warranty runs out. Thanks in advance.

I have never, with an automatic transmission or a stick shift, do what you described.   Exiting a highway would lead me to believe that you are decelerating from highway speed.  Why would you put it in neutral and rev it up?

OK first off, this is not normal behavior lol. I would never think to do this either but in gear while coasting, it wants to downshift and when it does it actually surges forward rather than slowing it down. Most good transmissions basically drop RPMs to idle as it coasts to a stop. I revved it in neutral just to see if it was gear specific or if it does it all the time - it's both. I think it's safe to say a transmission converter should not be engaged in neutral so I may need to look at babying this tranny before she goes POP. I hear they need fluid changed frequently so I may start with that. Sure would be nice if Ford hadn't taken the dipstick out of these so you could actually see if it's low or dirty. It's almost like they want to keep maintenance hidden from the owner so it blows a tranny and the dealer gets a $3000 check. Nah they wouldn't do that!

I have not done the coast rev procedure you talk about, nor would I do so.  A transmission oil change absolutely  would be a good idea at 75000 miles.  

Remember the computer talks to the transmission and can control the valve body.  Shifting into neutral with the stick is no longer the same as it was  before there was a transmission computer..  

A road test with Fortrans or a  advanced  scanner will give a good picture .

Your test  will not give the same picture of condition that it use to.
