Have been curious as to what would happen to the firmness of the auto tranny shifts with a fluid change to either Redline or just a conventional type F.
I'm worried about the amount of slip that the stock tranny allows;just can't be that good.

My Maxima buddies are in the process of convincing me to go with fully synthetic oil and a tranny cooler....
Will do soon!....Anh(another CL member here in Austin) just recently did a tranny cooler for under $150...Good piece of mind as well as adding life to your tranny...Tiny

Trans cooler is an excellent idea but keep the Toyota Type IV. These trans go for 500K miles on average, it must be doing something right so why risk it.

I too am wondering about this "life of the car" tranny fluid. I have always changed the fluid @ 30K miles since I had a Celica kill a tranny @ 32K miles. My Lexus service manager assures me that I will not have to change this fluid just like the book says. I am still concerned about it though. Any thoughts? Thanks

I was under the impression that the ATF was to be changed every 15K.
Don't know where I heard that,but with the slushy way these cars shift,I'll be changing often until I find out a good way to firm up the shifts.
Really will just replace the auto with a six-speed after it bakes itself,but will give it the benefit of frequent changes in the meantime.
