Clutch engaging in NEUTRAL!!! Toyota hasn't solved it yet...
 

Has anyone else had this issue?

Cold start...and it has to be pretty cold out...but cold start, let clutch out, RPMs drop 200-300 and in neutral she pulls forward a few inches. Put clutch in and RPMs raise back up..let out and they drop... When it first happened I felt it just bump the ebrake some...but when I put the ebrake down the car actually pulled forward a few inches. Once warmed up there is no issue and no pull. Car has been with toyota for almost a week now with no answer yet as to why.

Any help is appreciated! Thank you!

Why would the car move forward in neutral. Something doesn't add up. Make us a video.

In a manual trans, there are parts rubbing against each other even with the engine in neutral.
The drag for the oil (which is worse when cold) will exert some torque on the gears even when they are not engaged.
This is in the needle bearings between the gears and the drive shafts.

This is normal.
Now if you said it was doing that with the clutch disengaged then you have a problem.

If you start a man trans car in neutral on jackstands, the wheels WILL begin to spin up but you can stop them with just your hands.

It`s normal. Don`t sweat it.

Just exactly how cold are you talking about. A 2-300 rpm drop when releasing the clutch in neutral is not normal, and there should never be enough friction in the system to move the car on flat ground in neutral.

That doesn't sound normal to me. Sure there is still a bit of friction, but friction from fluid shouldn't be enough to move thousands of pounds of car forward. On jackstands you can see there is normally so little force that you can stop a wheel with one hand.

This is 100% normal.

I'm so confused by all the details in this thread

What oil are you running in the car?
What clutch do you have?
How cold is "very cold" at startup?

Seems like your fluid is causing some type of excessive drag on the input shaft, which is making your RPMs lower when the clutch is engaged with the flywheel.

The armchair mechanic in me thinks your transmission fluid is too thick for your temperature range.

Exactly. If I leave my track gear oil in over the winter and start it up on stands I can't grab the wheel and slow it down unless I want a finger taken off.

I have a feeling the OP has OEM fluid, which slightly surprises me that the car physically moves, but who knows.

Perfectly normal. All of my cars have done it in cold weather - significantly below freezing. This is a pretty light machine.

What you are experiencing is normal

Even though many have said it already.
