Changing transmission fluid

I have 75,000 miles on my 2017 tundra. Should I have the transmission fluid change now?

 

Definitely. Research how to do it properly. Change xfer case fluid (if 4wd) and diffs as well.

 

Assuming you’ll be keeping the truck, sure. I started doing drain and fills at 45k. At this point if I was you, I’d consider doing a 100% replacement at the cooler then doing drain and fills every 25k or so.

 

Okay. Thanks for the reply

I am researching on how to do it right and I have a bunch of good videos on YT

 

Youtube - The Car Care Nut's recommendations. Great channel.

Oil & Filter: 5k miles or 6mo. (Amsoil, personal preference)
Transmission Fluid: 60k or 6yrs. (OME)
Coolant: 50k or 5yrs. (OME)
Differential & Transfer Case: 30k (OME or Aftermarket)
Power Steering Fluid (Aftermarket Fluid)
Sparks Plugs: 120k (OME)

 

Hey, I use Amsoil for everything too...I have a 21 Tundra..62 000 KM...gonna change the tranny fluid...dealership says can't fo an exchange or flush cuz there's no hook ups for their machine...I'm going to do a drain and fill...should I bother dropping the pan...bolts look good on the pan but I've heard conflicting opinions...I live in Ontario (rust belt) but I do grease and oil spray truck every year...thoughts?

 

I would NOT drop the pan. The pan gives you access to what people call the 'filter' (and some of the electronics), but it's more of a 'screen' and doesn't need to be changed out like a traditional filter would... Drain and fill, leave the pan in place, and you're good to go

Regarding the bolts... Most folks say snap at least a couple removing the pan (even on trucks that don't have rust), but they are generally older than yours. I don't think you'd be doing yourself any favors by removing them 'just to keep them from seizing up'; I think you're better off to only touch them if you really need to get in there and just expect a few are going to go when you do...

 

Shortly after buying my 21 new I removed each pan bolt one at a time and applied anti seize to the bolt threads. Be careful not to over tighten the bolts after using a thread lube.

 

My fear is that since most of these '21s (mine included) were built when the factories and 'ports' were having problems w/keeping skilled laborers on hand; it is likely many of these types of fasteners were done in a sloppy manner or crossed-threaded, etc... I'm guessing the liklihood of snapping a bolt or two that wasn't installed correctly in the first place is fairly high for our rigs that were built during this period.
