Oil used: Redline MT90 (75w90 for manual transmission w/synchros) and Lithium grease.
I have 65 thousand miles on my car now and lately I've been hearing a constant squeak coming from my tranny.
I heard a lot of good stuff about Redline MT90 tranny oil so I decided to give it a try. After looking in the GTS owners manual, I found that the 2zz tranny takes 2.4 quarts of oil.
I went down to my local speed shop and bought 3 qts for $9.95 a qt.
After I got home from work, I decided to do the oil change. I jacked up the car with 4 jacks. 1 on each corner of the frame and made sure it was as level as I could get it for best oil drainage.
Unscrewed the fill plug on the side of the tranny and unscrewed the drain plug and out it came into the catch pan.
I fabricated a device to funnel the oil down into the fill hole. I used a garden hose about 2 ft long and a funnel. I attached them so I could flow the oil into the tranny through that cramped space of an engine bay. Before all this, I had to remove the drive side under engine plastic panel and front driver side wheel.
After replacing the oil, I let it idle for a while and as I shifted through all the gears with my foot on the clutch. I could tell right away that the smoothness of the shifts.
Test drive: I love this stuff. It made shifts extremely easy especially since I have TWM short shifter. The 1-2 shift is VERY smooth now. I haven't tried lift yet because I want to at least put 20-40 miles down so the oil gets circulated thoroughly.
Yesterday I used a can of spray lithium grease to lube my shift links located under the CAI
and ECU. After thoroughly spraying the links, I put on a surgical latex glove and rubbed the grease deep into the joints each time I put it into each of the 6 gears and the reverse gear. It helps if you have someone cycle through your gears while you lube the links.
Tranny oil per qt was $9.95
Spray lithium grease was $2.50 at Pep-boys
Highly recommended to those who want smoother shifts and prolonged synchro life.
