I have a 02 max with the 6spd non hlsd transmission with over 112,000 miles on it.

it has never been drained/flushed, I havn't had any problems shifting or coming out of gear while driving, but I am starting to do some Matinance to the car due to spring coming up.

but before I go ahead and do the transmission was wanting to get an idea if I should do it or not.

like I said I havn't had any problems with the transmission thus far.

so would I benefit from draining/refilling/flush? or just leave it be until something happens?

Thanks.

 

Maintenance is always a good thing to prevent problems before they happen, for me when it comes to the transmission there are a couple of things to check first. As you said you have no slipping or grinding those are very good points, you can check the color of the fluid on the stick if it is a nice redish color that is also very good, then give the fluid a smell test you don't want to have any burnt smell. So if there are no issues with performance, nice redish color and no burnt smell I would not do any drain and fill, just leave things alone. Don't let any of the shops try and convince you to do a power flush as that will just sent crap from the pan back up into the transmission, only perform a drain fluid, replace pan, and refill for the best results.

 

is it automatic or manual?

if it's auto just doing a drain and fill over the next 2 years should suffice, to slowly introduce new fluid into the torque converter and solenoid pack

 

awesome! thanks i'll check it asap! thanks for the great info!
as stated in the original post its a 6 speed manual lol. but thank you anyway

 

oh ok, wasn't sure because the 2nd poster had mentioned seeing if the color is " red " .

the manuals in our cars color of gear oil is a honey color .

i'm going to be changing the gear oil in my car this weekend and will be using 80W-90 GL-4 Napa gear oil.

will take some pics of the process

 

ohhhhh gotcha, yeah im not too familiar with transmissions and what color oil Im supposed to change it out with and such.

 

it's a fairly easy project.

i think the biggest tip anyone can give you is always remove the fill plug first.


1/2 inch drive ratchet, unbolt left. then remove the drain plug and let it drip out ( color might be black or very dark depending on the last time it was done ) , then after it all drains out, reinstall drain bolt and use either a suction gun to suck up new fluid from the bottle, or use a funnel with a flexible neck. then fill until the gear oil come out of the fill plug and tighten until snug...thats it !

 

took a snap shot of the drain and fill locations


drain ( 12mm bolt )



fill plug ( 1/2 in ratchet )

 

just call me mane. very simple task basically drain and fill. do not remember how much RP I used but they will be able to tell u at the auto parts place. I am just using 75 90 RP.

 

IIRC it uses 4.8L, i just used 5 qts to be safe, or until the fluid starts to drip out of the fill hole

 

Here is a link of a vid that i found... the flush is for a honda, but i think it will work the same way with nissan... just a matter of identifying the correct hose with the Service Manual... Hope this help, it gave me some guidance...

You do not need to flush a 6 speed manual trans.. For any reason.. Ever...

Just drain the fluid, install plug, refill.

 

Just drain and fill til it comes out of the fill hole. I use Redline MT90, it keeps my shifts in cold winter areas smooth.
