Has any one done this yet?

 

I'm running Redline MT-90 and its ok. It's definetely an improvement over the stock junk but there is still more room for improvement (nst bushings and trd shifter kit should solve that)

 

care to explain what you mean by improvement?
?

 

It goes into gear much easier and it doesn't "clunk" like the original stuff when shifting into a different gear.

 

Royal purple tranny fluid. it does make a difference as far as shifting goes, especially when cold. it does cut out on some of the whine in first and second gear, also. still clunky... even with the TRD short throw... but better than how it was (with both)
