Scheduled transmission fluid change

Hi. Just bought a 2020 4x4 sport. I have read through the maintenance schedule. Unless I missed it I didn’t see when to change the transmission fluid under normal conditions. All I saw was when to do it under extreme conditions. Does anyone know when or did I miss it?

 

Yah at least 100k if not longer

 

Wow. Thanks for the quick reply. That was the same thing Dodge told me about my Caravan.... shortly before the transmission went out
What do most people do? I don’t believe in “lifetime” fluid.

 

Do a trans check if you think it was low from the factory. Check again at 30k, 60k check again and replace if severe.

 

Thanks all.

 

It is synthetic trans fluid (at least that is what the service mgr told me).

 

I’ve been doing an annual drain and fill since 45k miles.

 

When it comes to automatic transmissions and how busy these v6's can get towing. Don't care if its synthetic atf in there already. I still plan to drain and refill at least every 30k miles.

 

"Lifetime" means the average length of time the original owner actually owns that vehicle. Are you someone that gets a new vehicle every 2-3 years? If yes, then it would be "lifetime" for you. If you plan to keep for MANY years, like well after warranties have expired, then plan on servicing it on a regular schedule. If you drive a lot of highway miles and no towing or anything that would really heat up the transmission (and the fluid), servicing can be done with many miles in between. If you're hard on it you want to service much more frequently.
Good luck

 

High temps will ruin tranny fluid.
Other than that it shouldn’t break down under normal conditions.

 

once per year is good. drain & fill will only do 20% of total fluid, so your just giving it a slight refresh.

I did mine between 75k - 80k on a 6MT.

 

When I had my 2010 I didnt do the trans fluid for 100k and never had no issues after that but with my new 1 I probably will take it more seriously

 

I’d do it every 50K miles. “Lifetime” is subjective and even 100K is if it never runs hot. The fluid breaks down quickly with excessive heat and you don’t know when it’s running hot. Very cheap insurance to change it at 50K miles.

 

Had a 99 and I had over over 200k on it and didnt change it but every 100k and never had issue with it. Miss that truck very reliable Tacoma. All original

 

The fluid is like a fine wine. It gets better with age.
