Hi guys, got a question that I'm unable to answer after searching. What's the general consensus about doing a drain and refill on a high mileage 2003 Sedan with 207k? The previous owner was an ex who had it pretty much since new and she can't remember when it was changed last, if it ever has been. The transmission has zero issues but I would like to service it before the summer here in PHX. I had a buddy who is a mechanic tell me with that kind of miles he would just drive it. I'm not so sure.

Any advice appreciated!

 

i would change it.. i never bought into dislodge b.s...

 

Drain and refill is good. Stay away from the flush machines.

 

Way to tell if it's been serviced is to check the color of the fluid...red is good, black not so much. Since you have no warning on the dash just do a drain/fill, no worries.

Thanks guys! I feel better now. Now, the question is, do I buy Nissan fluid or the Castrol import stuff?

 

Re-read what I posted!

 

my bad, it was the fine print I didn't catch. Thank you sir

 

Lol

 

I would be cautious. I know a lot of people consider it bs, but my grandmas tranny had high miles and her tranny took a **** when my dad decided it was a good idea to change the fluid. I do NOT, however know whether he flushed it or drain n filled. I think there is some credibility to the rumor.

 

186k on mine..i have used castrol import multi vehicle since around 100k. I would do a drain and fill, another in 10k mikes and another 10k after that. I do a 10k (every other oil change) and figure i exchange about as much fluid as a flush would every 30k.

 

Also, did he use the right fluid or whatever was cheap?

 

Hey, there are many opinions here on what is "right" when it comes to servicing an old transmission. What I can guarantee you is that if you flush the transmission clean you are going to have a bad time. All you need to do is drain from the drain plug and refill back up top.

If you are on a flat surface it will take exactly 3.5qts. Last two times i've changed mine it has been exactly 3.5 qts. Do not drop the pan on your first change. If you drop the pan on your second change purchase an additional 2-3 qts.

You will also need a new transmission gasket when dropping the pan.

 

Anyone find the pan gasket for cheaper then $20?

No, he used the right fluid, but it had never been changed before. As the rumor goes, if its never been changed and you have high mileage, you should just leave it alone. If its changed regularly and on schedule you are good regardless of mileage.
