yes I would change all the fluids in the engine, tranny, rearends, and also brake fluid.How often should I change my transmission fluid/filter?
if it sat that long then i would definitely change the transmission fluid and filter along with the transfer case and rear end. it will be better in the long run to do so.How often should I change my transmission fluid/filter?
Depends on your driving conditions. but once a year is fine. once every six months. even better!
