I have a question about trans fluid for you pros on here. I am getting ready to pull a 4500lbs trailer 5000 miles from Alaska to Michigan in a couple of weeks. My titan has 34000 miles on the truck and the trans fluid has not yet been changed. I check the fluid and it smells fine, but it is no longer bright red it is starting to fade. I live in a small town in Ak and trans fluid choices are limited. I have found 5 quarts of Royal purple max ATF and 6 quarts of Valvoline MEC/Dex ATF fluid at the local auto parts store. I was thinking of doing a spill and fill because I can only get enough oil to that. Which oil would you fellas go with and will it be okay to just do a spill and fill with either of these oils?

As long as they meet Nissan Matic J specs (or Matic S if you have a newer truck), then pick whichever one you like better. I've been running Royal Purple ATF in my truck for the past 75,000 miles and no problems.

The spill and fill is a good idea, but mixing brands..... not so much in my opinion. If you still have two weeks just order some Genuine Nissan Matic-S online.
