Very well actually but if it should have dinosaurs that’s what I’ll get . The oil has only been changed in the transmission twice in the ten years since I’ve been around the truck The first time I changed it, the truck belonged to a guy I worked for had to scrape out gear teeth shards our the bottom of the case from the years of abuse and super truckers floating gears or trying to I should say. I bought the truck five or 6 years ago and I decided I had better change the trans mission oil again this time when I drained and took the cover off there wasn’t any gear teeth I also added a filter to transmission
