Need advice (auto transmission)

[Swedishmoose]

Hi guys,

I tried to find information about my issue (if it is an issue) but couldn't find anything.

So i'm hoping that somebody here might have a light bulb moment.

I started our 2000 Falcon Futura in our garage this morning when it was kind of cold (5 C). The garage is levelled.

When I put the auto in reverse i moved about one meter backwards and then i put the auto back in neutral because i forgot something in the house.

The moment i put it in neutral and lift my foot of the foot brake, i noticed that the car was still creeping forward just slightly.
When I prodded the throttle the car was reacting to it even though it was in neutral.

I repeated it again but put it in drive (D) this time, rolled forward a bit, put it back in neutral and it was again creeping forward just slightly.

Could it have something to do with the thicker cold transmission fluid in the morning?
When the car had reached operating temperature, everything was fine.

The gears are definitely not engaged which would mean that the shifter linkage would need adjustment.

I also noticed when it was so cold this morning, that when i put the auto in gear the RPM didn't drop instantly from 700(N) to about 500(R, D). It was a bit inert and slowish.
Same when I put it back in neutral. Usually the RPM goes back up from 500 (in gear) to 700 (in neutral) instantly, but it was also a bit inert.

When operating temperature is reached everything is fine.

I also don't know if these two things (car slightly creeping forward in neutral when cold) and RPM adjusting very slowly when cold in neutral and in gear have something to do with each other.


Hopefully it wasn't too confusing.

Anyone an idea ????
