Based on alot of imperical data I collected on both this site and other Subie-oriented sites, I decided to change my MT to 100% Redline LWSP for my 60k servicing. Everything went well, for at least the first few thousand miles...then, things began to change,and NOT for the better!
I noticed that I began to get a grind on the 2nd to 3rd shift, especially when shifting quickly. Then, it got to the point where I had to gingerly almost "place" it into 3rd gear. Then, it began grinding on the 3rd to 4th shift, so I decided that measures HAD to be taken to preserve not only my sanity, but my gearbox as well.
So, angry, I went to my local parts store and bought the ONLY gear oil they had available on hand- Lucas GL-5 80w-90 oil. I know its not the right viscosity, and I can tell its affected the performance of my XT because of its thickness(now it feels like I really have to spin it to get it "on boost"). That being said, the grinding is gone and the gear noise I typically hear has abated. When I drained the Redline, I checked the mag cap and found there to be some metal shavings...not alot mind you, nor were there any chunks or flakes (which I expected to find), but the shavings were there, which is rather disconcerting, because it was obviously cleaned when I serviced it not 5k ago.
I should mention that I had absolutely NO issues with any shift "feel" or engagement problems prior to changing over to this product. I purchased the car with 27k on it last year and have almost 60k on it currently-my only mods are a K&N filter in the stock airbox, an afta-MAF Perrin hose and a Cobb ST 1 tune. All of these mods I had installed at around 45k miles.
My questions are these:
1) What sort of damage has been done to the synchros with this product?
2) What type of gear oil should I switch to?
I really enjoyed the smooth shifting and the fact that I felt like I was getting more power from the reduced friction of the Redline product, but, obviously, I'm REALLY leery of putting ANYTHING like that back in my trans.
I was thinking of putting in some "S" type subaru 75W-90 gear oil, or something similar to that. Anyone have any suggestions? Oh, and I'm not really keen on the Uncle Scotty's "brew"- I don't know why one would put synchromesh in a trans that isn't made for it...but I digress. Any thoughts would be welcome! Thanks!
