Towing it behind a truck with the front wheels in the air is a huge
That will damage the underside of the car.

Towing on all fours at low speed (<35 mph) for a short distance (<50 miles) would IMO not damage the gearbox as oil is being circulated.

This is where I think the oil pump is, if I understand the manaul correctly.
Driving uphill for a while (on the Dragon I've seen a movie linked to that on the temp site) does not damage the transmission.. does it?

Another thought:

Idling your engine to operating temp is much much harder for the transmission as the primairy shaft is spinning at engine idle speed (1200-900 prm) without any oil supply to its bearings and 3-4-5-6 gears needle bearings on the primairy shaft do not get any oil either.
Only what 1st and 2nd gear set are splashing around.

 

well too late...

my car got towed before with the front wheels in the air...

all seems fine for now.

do you think the damage will gradually get worse? or just one time damage?

cuz my overrev damage was very very gradual...but engine and trans are different...

If it was towed that way for the 10 miles you posted earlier at slow speed you may be allright.
IMO the slow speed is important.
There's nothing you can do about it now anyway.
(don't do it again )
Nothing underneath got damaged? Exhaust tips? Rear bumper?
If the front wheels are lifted too high its easy to see the rear can get damaged.

For some piece of mind you could change the transmission oil and watch for metal shavings.

Using a flatbed is still the recommended way to transport the S2000 if it can't be driven.

thanks...no damage to underside. no scrapes on exhaust.

changed tranny 2-3 times since...no metal shavings observed to flow out when i drained it.

thanks.

 

word look for shavings...stick a magnet to the base and drag it to the opening to pull shavings out.... if you seee some....thats bad

Also everyone should have known about the tranny spin in neutral... it's why when you double clutch "which ive noticed most people dont even understand still" you let the clutch out in neutral to match rpms. Clearly something is spinning or this wouldn't be the technique

 

I know its slightly off topic...

My point was that if someone thinks they are doing their engine a favor by letting it idle to operating temp before driving it (when the car hasn't been driven for a while or its been parked outside in the cold, or.. whatever you can think of) they are making things worse for the transmission as the primairy shaft and 1-2 gears are spinning without the oil pump providing oil anywhere.
The gearbox oil would most likely be cold & thick & most of it drained to the bottom.
Not an ideal situation IMO.
