Thanks for all the info. No idea when the stuff was last changed since I just bought the car. A shop quoted me 70 bucks just for labor to change the fluid. I figure I can probably buy some ramps and fluid for that price. I've read that redline MT is good and that's what I'll probably use. Any other suggestions for an old tranny with tired synchros?

Thanks, Just read the reply from the other day too (doh!) Should have searched better. Any reccomendations for fluid? Its a 2WD Wagon with some synchro problems. Is the plug easy to spot once under the car? Is is just drain the stuff and add the amount specified in the manual?

Hi, Synchros seem to be quite worn on my 88 GL Wagon. Think its a SPFI or MPFI. Read on here that changing the trans. fluid to Redline MT might help get some more life out of the transmission. Is this something I can do in teh parking lot of my apt. complex? Have some mechanical knowledge. Any tips? What tools will I need? Any info would be greatly appreciated. thanks

I don't think its related to the oil anymore. The oil level seems to be fine. Not even sure what type of engine I have - it's an 88 GL wagon so I think it s a multi point FI. Not sure though. The product I was told about is called Rislone Ring Seal. Would I add this to the transmission fluid?

Any idea what might be causing this now intermittant fluctuating idle? Just started her again and its idling better but not perfect. Bad MAF? Also what the name of that stuff to help the snycros? Does it work? Thanks

Yeah that's fooled me before but it s on tight now. I think having the cap off might mess up oil pressure. Just a guess though.

Hi, Complete subaru noob here. Just bought a 1988 GL Wagon with the NA 1.8 liter engine. It has about 136,000 miles. It burns a little oil and I noticed it was on the low end of the dipstick. I addes about 3/4 of a quart and when I started the car again it had a rough idle that bounced from about 900-1200. It didn't do this before - could I have overfilled the oil? The car was running perfectly before I added the oil and idled roughly instantly after. Also, the syncros seem to be worn from 2nd to 3rd - is there anything I can to ease the damage to the transmission. I though I had heard of some additive. thanks for the help, I'll be around here more from now on. hopefully sharing advice as I learn about these cars.
