That SAE90 is probably for the reardrive gear. The transmission shares oil with the motor which certainly does not run SAE90 or 80. Another possible culprit could be water in the hydraulic lines. If it got cold enough to freeze it wouldn't be very hydraulic anymore. Flushing and replacing that might be a good idea too.
