| Received my 98 spec transmission and it was supplied with the OEM transmission fluid. I also purchased MT90 with the transmission because I thought it would arrive dry (without fluid). QUESTION 1: Should I run the transmission with the OEM fluid or flush it out and start fresh with the MT90? QUESTION 2: Should I run the transmission with the OEM fluid and at the end of this year (or other frequnecy) flush it out and refill with the MT90? Thanks for looking!
