My tranny fluid is like a dark maroon sorta brownish red color. the car just today gave me a lil problem. When i floored it from first gear, when the car shifted to second gear it kinda lagged a lil before it would shift to second???? WTF does this mean. should i changed the tranny fluid?? should i do my VB upgrade with new tranny silinoids?? Im at a lost here please help

 

Sounds like it is time for a flush. Regular tranny fluid is clear red. How many miles since you last changed the ATF?

 

i dont know if it has even been changed i bought it used. should i just do a lil drain and fil?

 

There is also a TSB out for your year I30 for a slow 1-2shift which is fixed primarily by an updated TCM software.

 

realllyyyyy where i need to knowwwwww

 

yeah, you could do a drain and fill, but I think if I were you I would do a complete flush. I've been draining and filling every 20k miles since new. So my ATF fluid never really gets old. Draining and filling on a car of your age (what is the mileage?) may not be the best option.

Some will say you shouldn't drain and fill after a certain mileage if you aren't having problems, but I never understood that.

how often should i change my tranny fluid?

 

Its good preventative maintenance to change it about every 60K miles. But you should always check your fluids color.

 

thanks guys, oh by the way should i have the tcm reseted or reprogramed? if so how much does it go for??

 

I'd say every 30k. But tehre is a TSB for the 1-2 shift slip that states to replace the VB, I just orderd a VB from Max tuning b/c mine was slipping on 1-2, but not the 2-3.

 

so you think that will solve the problem there telling me to changed my silinoids as well and have everything done at once. I might just do all of that the vb mod and the silinoids.

 

i had slipping pretty early on in my the transmission's life. i had the tcm and solenoids replaced under warranty and all slipping went away. i also do a drain and refill with mobil 1 atf once a year and run a moderate sized tranny cooler.

 

Color of the fluid doesn't say anything about the viscosity, oxidation, stability, friction quality etc, Nissan trannys are brutal on fluids and a 30,000 mile OCI with dinos and 60,000 with syn is optimal. Oil analysis should say how far one can extend the OCI.
