Spends too much time on here
No, I won't consider ZFs recommendation either. I've not changed trans, dif or transfer case fluid in any truck i've owned since the early 1990s even when the manufacture recommend they get changed. I change my oil when the oil indicator says to change it; normally between 8 and 10K. Never had an issue with any of them and I can afford to pay for a problem with the money I've saved over the last two decades not performing this service.
Don't know and don't really care enough to call them. I have no reason to question their price and those who are claiming it's an impossible price are all posting fluid prices that are 2 - 5 times higher than what it can be purchased for. They add the price of the pan and filter, but I don't think the fluid change price includes that as those service are listed separately.
I suspect it's an error on the site, though it honestly doesn't matter.
Whatever works for you, it's your vehicle.
