Fellas:

My GS has 43,000 miles on it and is a '99 GS3.

Tranny Fluid has never been changed.

Should I do a complete tranny fluid flush or just a drain and re-fill?

Is Max-Life Tranny Fluid OK?

BTW< I have had some issues with performance where the car takes forever to get up to speed (50-60mph), might this have anything to do with Tranny Fluid?
I have checked most other known culprits - MAF Sensor, TPS, vacuum leaks etc.

Ted do the drain and fill

this is what Lexus does

i would stick with the Toyota fluid

 

yeah most of the time you can just do drain and fill. unless you are **** as some of us (including me) who pays a lot more for a full flush

 

Far as I know the only T-IV replacement fluids are Amsoil and Mobil, and they're synthetic. There's another recent thread on this floating around.....

 

Definitely get TOYOTA Type IV "Red"

SAVE big money got to the Toyota Dealer and have them dot it.

1. You'll get the same fluid as the Lexus Dealership
2. The procedure will still be in the Lexus/Toyota Service Database.

 

Yes it is good stuff, BUT you still have to change it regularly. It does get dark because the transmission gets hot.

I went from TOYOTA to AMSOIL UNIVERSAL TRANSMISSION FLUID AND a HAYDEN TRANSMISSION COOLER. My transmission runs a lot cooler, with no loss of performance. It also stays cleaner longer than TOYOTA fluid.

YOUR CHOICE

 

hmm.. i was under the impression that the T-IV was the only optimal one to change tranny fluid. I think i will need to do that on my GS... it's heading on 6 yrs old... havent had a tranny change since 3 yrs.

 

some say 3 years 36,000 miles

so you are about due

and it is the t-iv ...but companies are starting to see the light i guess

 

Ted,

Read this thread (https://www.clublexus.com/forums/sho...d.php?t=158500). It discusses pretty much everything you need to know about drain/refills and fluids.

 

will schedule soon.

 

This is also a pretty easy DIY

 

for real? no need to bring down the tranny pan?

 

just like changing the engine oil, just unscrew the drainplug. Look here: http://lexusmodz.netfirms.com/GS_DIY...il/index1.html
