Transmission service

How often should I service transmission? Dealer says 90K miles / 6 years. Same question for 4WD components? There the dealer says 60K miles / 6 years. Manual is mum.

4wd. You should engage for a few miles every few weeks

 

I changed my fluids in my transmission, front and rear diffs, transfer case and radiator at 50K miles. Some might say I did it too soon, but nobody should be able to say I am neglecting my truck. The link Chew posted in post #2 above has some great How To videos if you plan to do the maintenance yourself.

 

The graphics and videos are great! Very helpful. I noticed the service intervals are based upon mileage only, whereas Toyota also includes mileage or time. The time must be for low mileage drivers.

 

That is why I did my fluids at 50K miles. My truck is 9.5 years old and I only currently have 61K miles on it.
