S14 Auto. AT warning light.

When I start my S14 it sometimes gives 15 flashes of the AT/OD off light on the dash.


Have had a search and can't find the decoding on the forum for this. Does anyone know? :)


Setup:
Auto converted S14a Turbo
Full loom transplant
Low miles gearbox from imported NA Silvia.
ATF front mount cooler from Ford Focus


Thanks in advance. :notworthy
