so is the 75w-90 just a really think motor oil or is it the special auto tranny fluid?

Manual Tranny Fluid
 
This stuff is MANUAL transmission fluid, AKA Gear Oil. 75W-90 is the kind called for in my owner's manual. It is rated by viscosity the same as motor oil, but comes in a different container, and is more expensive. Do not, I repeat, DO NOT put it in an automatic transmission, you wil F*** it up. Check your owner's manual for the ATF you use, there's a number of different formulas. The procedure for an Auto is different, as well, most don't have a drain plug, so you have to drop the pan to drain it, and you will have to fill the tranny through the dipstick. Not impossible, but messy and a real PITA.

Oh yeah...
 
Oh yeah, and whatever you do, don't put any kind of ATF in a manual transmission, you will kill it quickly.

At least on first gens, there is an auto tranny drainplug...but you basically gotta drop the engine crossmember to get the pan out of the way too... d'oh :o

damn i totally misread the subject of this tread and thought it was for auto tranny's. Anyhow. My auto has a drain plug but as far as i can tell you have to fill the thing from the dip stick.

kansei June-28th-2003 06:12 PM

In an auto yes fill through the dipstick tube.

THEGOLDPRO July-1st-2003 01:30 AM

according the the haynes manual you have to drain through the bottom plug and refill through the speedometer driven gear case hole (not sure where that exactly is) and yeah its 2.8 quarts... well 2.83 but i'm sure i can measure out that .03 part the 1.8 L tranny takes 3.55 almost a full quart more... i'm hoping to change my fluid this weekend or early next week...

kansei July-19th-2003 09:48 PM

1 gens fill through the speedo ,2 gens have a fill plug on the frt. This for manual only ,auto will drain on bottom and remove pan if you want and fill through dipstick tube.

protegeboy78 July-19th-2003 09:58 PM

so is this a pretty quick thing to do? or will this take a while? and do i need a new bolt and washer when i'm done?

kansei July-19th-2003 11:20 PM

It wouldn't hurt to put a new washer on but it is usually not needed.If you have any question about the washers (fill and drain) replace them, they are just copper washers and you should be able to get them anywhere, and open the fill plug when you drain ,it will drain alot faster.

pcguy2k1 July-22nd-2003 08:56 PM

The fill hole is the one that's angled down slightly, right? It's the only one I see on the front, and the drain is located way back on the bottom close to where the shift fork enters or so? It's the only 23mm bolts I found on the Tranny so far, didn't want to go ahead and mess my car up, so I'm making sure.

I discovered that my battery cable the positive plug was a little to big for the connector sticking out so it was loose, early loose to the point where it was capable of coming off :eek:. And it was thightened all the way :eek: . Oh well pliers work well in some cases, bent it down to a smaller shape and it fits, maybe that will solve some odd idle problems. We'll find out and see on the drive to work tomorrow.

protegeboy78 July-23rd-2003 07:40 AM

what size washer do i need? or how do i find out without pulling the plug cause i can't drive my car to the store to buy a washer after i've pulled the drain plug
