My car has 180,000 and I have zero transmission fluid changes, on a manual. They said it’s lifetime fluid, but I’m not sure if that’s my lifetime, the car's lifetime, or the transmission’s lifetime. Guess we’ll find out.

My bud has Ram. The tranny went out at 125k. The tranny is sealed with no way to change fluid.

I looked up the expected life of the truck. It was 150k lol.

My 17 ford truck has 155k on it. The oil gets changed every 5-7k. I change all other fluids every summer before we start camping. That’s transmission, differentials and transfer case, I’ve done the brake fluid, power steering fluid, and coolant once . I’m hoping it lasts a long time and I plan to give to my 13 year old son. It’s about to be on its 4 set of tires.

The fluid in an automatic lives a much harder life than the fluid in a manual trans.

ATF is constantly being shoved through valves, picking up clutch fibers, gets hotter, faster than a manual.

Biggest problem with the gear lube in a manual trans is condensation contamination if you do a lot of short trip driving.
