I took it to a-affordable transmission in colorado.
After a 20 min drive to the parents i stopped on the street and reverse engaged fine. I need to see if manual 1st doesnt engage when reverse isnt working.
I called the shop and they said the viscocity change could have clogged a valve or something, and to drive it for a week and if it still does it then bring it in.
Thanks for the suggestions guys, updates to come...
