No I did not go to the link but I bet I already read the thread he linked to.SnowbordrWRX said:
Yeah right now it shifts nice but wait a few thousand miles and see how it is. Like I said most people love synth oil in the trans initially but then after a few thousand miles they are having problems.STiGirl said:We just changed mine this weekend, and called the dealer to verify what they used. They told us 80/90.
I ended up going with Mobil 1 Synthetic 75/90 and I'm happy with the results. Going into gears are a slight bit smoother.
Coming from the Audi 6-speed (mated with the 2.7T, not the new one for the 4.2) I have to say the gear change in this car is damn nice. My Audi's tranny was so notchy it wasn't even funny. I wouldn't touch a thing, because in my mind it can't get much better.MKIVSupra said:From what I read the problems have to do with the synchroes. The bearings love a good slippery oil while the synchroes like some friction to get into gear. If you drive normal and take your time shifting you can get by with a good synthetic. If you shift hard and fast, too slippery of an oil will give you problems getting into gear down the road.
At 11k miles now my trans shifts beautifully. I am almost scared to even mess with it. That is why I am really having second thoughts and decided to wait till spring before I change the fluid in the trans and diffs. I read a lot of posts on different forums about people changing to a synthetic and saying how great it is now only to come back a few k miles later and say how it grinds or is hard to get into certain gears.
Hey I am not saying that synthetic is bad to use I am just stating what I have read about people's experinces. I have yet to read one post from a WRX owner that with long term use they had no problems with their trans after switching to synthetic. None of them used any special racing formulas just your basic redlines, royal purples, mobil 1s, etc. There are a lot of things racing teams do and use but they also rebuild things on a regular basis. I am all for synthetic fluids and religiously use synthetic motor oil. I really want to switch to synthetic gear oil but based on what I have read so far I would rather just use regular gear oil and change it more often.crashsti said:i think if you look at any and all major racing classes and teams everyone is using synthetic oils, be it gear or engine. the only downfall to running synthetics is cost. in every other way they beat out conventionals. be it in reduced friction or in resistance to heat. it is possible that someone used the wrong synthetic in thier gearbox. most companies make a RACING formula that is not recommended for use on the street. its possible that someone used a racing variation and that could have been the issue.
