Transmission fluid is more rose colored, motor oil will
be dark brown/black.
When you check your transmission fluid the car has to be
running and the dip stick has two level ranges one is for
when the car is at a lower temperature and the other side
is for when the car has been running for a while and is
hotter.
I also have a small tranny leak, I live with it for now,
but will fix it soon on my 83 DL (automatic). When my tranny fluid is low the
car has trouble taking off when shifted into gear and this
seems to be when is happening with yours. Don't let it run
low on tranny fluid or your will kill your transmission and
thus maybe the car. Check your owners manual for the correct
type of transmission fluid to use on your model and always
use what they say to use....they know what fluids were best
for the car.

Good luck and do let us know the results...it helps others too.
