Default Tranny flush hard?

I think I need to flush my tranny on my 98 legacy brighton, is it hard? what kind of fluid do I need? Because sometimes it's feels kinda rough to get it in gear.

it culd just be low, or the torque converter could be oing bad. But yeah, start with a drain and filter replacement. It is not too hard to do. Just remove some bolts, clean up the pan to remove all the residue that settled in it, replace filter, replace gasket, bolt back up and fill. It is a very messy job, though. Wear OLD clothes...

Oh, when I think of tranny flush, I think of an auto. To change out the gear oil isn't hard on almost any manual trans. You just remove the filler plug and siphon out the old stuff. Pump new stuff back in and close it up...

A tranny flush means that you take a machine and flush out the transmission - that's pretty much only done on an automatic tranny, FYI. Just changing out the gear oil isn't hard at all. Just like an engine oil change - drain, drain, drain some more, and then fill 'er up. It's hard to get it all out, so fill it up with approximately what you drained. The dipstick is near the back of the engine bay, sticking out of the transmission.

There are a number of routes you could go for tranny fluid. Among two reccomendations are doing Uncle Scotty's cocktail (search for it here on Nasioc) or the Redline Lightweight Shockproof/ Gear oil mixture. I forget the ratio of gear oil to Shockproof.

Check your owners manual or a Haynes manual.

It's on the bottom of the tranny. If you know where the ENGINE OIL drain plug is - it isn't that one.

the manual transmission drain plug has a giant square cut into it, and faces straight down from the bottom of the transmission case. i think you use a 1/2" drive ratchet to loosen it (insert the ratchet directly into the square hole, don't use a socket), it's been a while since i changed the tranny fluid in mine so i forget the wrench size. but yeah, just take the plug off and let the old oil drain out. then wipe all the shavings off the inside part of the plug (which is magnetic and catches all the little metal shavings that are floating around in the oil), and then replace it when the fluid stops coming out. put it on tight, but not too tight. pretty much just do it like you would do the oil drain plug.

then get inside the engine bay and look towards the back of the engine, on the passenger side of the car. you might need to remove the intake arm to get a really good look at it, but the dip stick is a small yellow one stuck right on top of the transmission. take that thing out, insert your funnel (get a long neck one, or at least one with a hose attached), and pour in about 4.2 quarts of your favorite gear oil. 75-90 weight is the recommended type, i use Mobil 1 myself, but everyone has their opinion on what is best.

hmmm, looks like maybe some of the subaru manual trannies use a 17mm or possibly a 19mm bolt then for the drain plug (which should still be magnetized. i know my automatic uses a 19mm, but i swear my manual uses the 1/2" drive hole...i'll have to check it out next time i'm down there.

and i know what you mean about being able to just do everything at once. unfortunately my wi-fi doesn't go out to the parking lot of my apartment complex, but i've been working on my cars too. just replaced the a/c belt adjuster on the white car (which i broke because i forgot to loosen the old one when i was tightening the belt down), and installed a rear wiper on the red car (which is a brighton, so it didn't come with one). now i get to swap the steering wheel on the white car (for a leather one from a GT limited!)!

For the newer Subaru's, you actually need to use a Torx T-70 to remove your Transmission drain plugs...

This way your local Jiffy Lube grease monkey wont accidentally drain your tranny fluid when you only wanted your engines motor oil changed.

i'm still learning this myself. i only bought this car back in October '08, so i haven't really had it long enough to experiment much with it. that, plus it was down for 2 months when the clutch failed and i had to save up to get it replaced.

i originally had the regular old valvoline 75w90 gear oil in it, but then switched to straight pennzoil synchromesh because the gears are grinding. next i'm going with straight Mobil 1, which is what i always use in my automatic.

Check the band adjustments on the tranny...a simple adjustment can make a world of difference.

Band adjustment is on a automatic transmission. There is no adjustment for manuals. It adjusts the brake bands inside the 4eat which the transmission uses to slow down and stop different internal moving parts (planetary gears, sun gear, ring gear). This is what the transmission uses to have multiple drive ratios (gears, or 1st, 2nd, so on).

I needed to look up that info anyway because I was talking to somebody about how automatic trannies work and couldn't remember the name out the outer gear (ring gear)
