Hey ya'll, i was wondering how many quarts i need to buy to replace my tranny oil... kinda a noobie question, but you gotta start somewhere. >_<
i was thinking redline synthetic. any opinions. i had a previous post on this and that's what came out of it.
thanks for your input!

 

I believe 2 QT's but you minus well go ahead and get three.

Redline/Royal Purple/Mobil1

 

FSM is available in the FAQ and it carries all that handy information

 

I always like to flush an extra quart through

 

how would you do that?

 

take the bottem drain plug out and theres another bolt higher up the tranny, take both out and just use something to put oil into the top bolt. It flush thet tanny, kinda hard to explain lol

 

why is it that some places charge a large amount to do this? Is the experience in flushing out, draining out the transmission fluid that much more complicated that flushing, oil change, draining out the engine oil?

last i saw someone told me it was atleast 100$ to perform this... is it a "do it myself" job? do u have images of where those plugs are located on the tranny? thanks!! =)

 

It doesn't really flush the transmission. It just runs down the side of the case to the drain hole and out into the drain. Kind of a waste of fluid especially when using expensive synthetic stuff.

Most transmission shops can do a real flush for a nominal fee. Involves circulating a solvent through the transmission. It's also not really required since transmission fluid is in a basically sealed environment and doesn't absorb combustion byproducts.

 

i also heard its recommended every 30,000 miles... ?

 

very easy to do... just a matter of getting up under your car and draining the oil out, putting the plug/bolt back in and refilling it in the top plug/bolt.

when you refill, would work best if you have like a hand pump but if you dont... use gravity... since you cant lift the bottle up above the tranny refill hole... i use an aquarium gravel cleaner vacuum tube... From the engine bay, run the small side of the tube into the tranny refill hole and have the large end be your "funnel" where you pour in the oil.... if i'm not mistaken, the holes are on the passernger side of the tranny... correct me if i'm wrong... i forgot.

edit: dont forget to pop a hole in the bottle for the air to get out of the bottle for when you pour the oil into the tube if you decide to take this route, will let the oil pour out faster.

omg that is an awesome idea... what about automatic trannys. mine is kinda fucked and well about to die. lol. my pan is coated in a nice layer of fluid. i plan on replacing the tranny with a 5 speed swap tho. later.

Yeah, I'm with rotarybeat. I changed the fluid in my N/A auto tranny by unbolting the pan, replacing the transmission filter and gasket then adding fluid in through the fluid check funnel under the hood. All the while using a pump to guess where the good level was after finding out that the check rod is wrong. I have no idea how the the tranny fluid level checker is the wrong one. All I know is that after replacing it to the ideal level on the checker I went to test it out and sat in my car as it rolled down the driveway without the gears catching in the tranny, I took some out and now it works fine.....for the most part.

 

thats what i was thinkin. just pooring in oil and letting it drain is a waste. the oil should at leats circulate the tranny so that it can "flush" out the old oil deposits.

theres a tranny oil filter? im guessing for automatics only correct?

 

smart asses that dont know what they are talkin about... HAH!!!

 

mine took 2.5 quarts, how you really tell is its soposed to be even with the fill hole on the side of the trans.

the drain is a 24mm and the fill hole plug in the side side is square, but you can use a 14mm open ended wrench to get it off

GM syncromesh is the best trans oil to use, soooo smooth

 

yea i totally forgot that what i said doesnt work LOL, sorry for the what is it called?? crap information LMFAO

 

Easy, you just drain it and replace it with a flush (they sell it everywhere.) It usually comes in a quart b/c it expands (almost like engine flush) and you put it in and drive w/ it for about 30min to an hour depending on what you buy. Then you drain it again and fill up. I like it b/c you only have to do it like once a year, but it gets alot of the impurities out of your tranny. Dont flame me, but I used to work at Jiffy Lube, so changing oil isnt too annoying to me any more.
