i have a 7fgcu15 sn# 69539 and when you run the engine for 5 to 10 minutes the light next to the check engine light flashes 8 times while the engine is running seems to be running fine but the other day was called out to the unit and the trans was real sluggish got it back to the shop and put it on the rack and changed the trans filter and fluid and cleaned the trans stainer out noticed the inching valve was not releasing all the way installed a return spring and all seems fine does any one know what these 8 flashes mean.
thank you
