Need to make another run to the auto parts store tomorrwow to finish buying everything I need for my engine swap, and Im going to get some tranny fluid and rear end fluid, what kind should I get? Any suggestions? Any particular weight? Thanks.

Actually, should be GL4 requirements
Do a search, some good threads on this subject. Some synthetics (like Mobile One) raise hell with the syncros's in the tranny. Something about some Synthetics being TO slippery. As a result, the syncro's wear out pre-maturely. I know as, sadly, been there done that.
Key point, stay away from GL5 if going with standard gear lube as the sulfates in GL5 is the bad guy. Look for GL4.
Synthetics...............the concensis is either Red Line or Royal Purple.

it depends. different oils are slippery and others not within the same brand. there was a big post on the mobil one synths and redline synths on impreza.com forum when i had wrx. so its not really just based on brand but also on which type of synth from that brand. which you think you'll need is based on your driving habits. hard shifter, you need a grippier oil for you synchros. don't shift hard but want better gas mileage go with the slippy stuff.

I just want something that would work well for average daily driving, but would help when I wanna get on it and go, so I guess Ill try and find something...So what standard should I get? Y'all got me all backwards and ****...I had no idea that there was that much crap out there.

So like 75-90 for me? This all doesnt make that much sense to me...
~T.J.
75W90 GEAR OIL - recommended for most street driven and racing differentials. Excellent performance in conventional and limited-slip units. Also for limited-slip manual transaxles which require a 90 WT oil. Contains limited-slip friction modifiers.
75W90 Gear Oil - the preferred product in nearly all car and light truck differentials, both conventional and limited-slip. 75W90 is preferred for most racing applications. It contains friction modifier which is recommended for limited-slip units. 75W90 Gear Oil can be used in many transmissions and transaxles; however, other Red Line lubricants have better frictional properties for rapid synchronization. Exceeds API GL-5.

why make different cars? one would move us where we need to go. same reason. we all use them for different purposes. my car is for sport driving and autox. so i want an oil that is synchro hkepful and screw the bearings and gas mileage. if this is your daily and your not that hard go with regular. the way you're talking i would say the 75w90 or mt90.
