it takes auto trans fluid (mercon). theres a drain and fill plug, but i think you will need a hand pump to get it back in there (3 bucks). the gt goes 1/2 below the fill plug and if its a mach it goes flush with the fill plug. have fun. :banana . oh it should tell u how much fluid in the owners manual.

 

i just drained mine with the bottom plug, then to fill it i took the shifter off and dumped the fluid straight into the top of the tranny..

 

This is the best way. Should be 3.3

 

How many quarts? I dont have a manual

 

I probably will pull my shifter off and fill from there , but how do u know when its full?? Im gonna use royal purple synthetic gear oil , but font know what kind and how many quarts. Oh and do u have to seal off your shifter when u pulll it?

I recommend this RP fluid. I don't know exactly how much to use but I know a gear kit comes with 3 bottles. :dunno

 

your supposed to use auto trans fulid aren't you? thats whats in mine

 

p.s. you could measure how much comes out, or take out your top plug any extra would run out i cant see 1/2 inch of fluid makeing a difference.

 

woah woah.. dont use gear oil. saleen0101 your car is an automatic? or is it a manual. you can't take the shifter off an automatic. or at least thats not how you want to go about filling your fluid.

 

No no its an manual 5 speed. sorry . what kind do u suggest? And do u think 3 bottles of royal purple should do it? Im just gonna pour three bottles through the shifter hole

 

these manual trannys use automatic transmission fluid, NOT gear oil. i dont remember what the capacity is. i think its around 3 qts. i do know for a fact that the owners manual has the capacity and recommended type of fluid though.

If you are right can someone explain to my why every gear kit on AmericanMuscle.com comes with that gear oil? Every single one. :dunno

Thats for the rear end, not the transmission.

After re-reading his first post, isn't that what he is talking about?

About to change the 5 speed transmission oil myself and need to knowhow many quarts of gear oil for my 2001 mustang and if its simple to do. Is there a weight like motor oil?

 

Are there different weights of auto-tranny fluid or what? Im gonna change mine to Rp soon as I get my shifter.

 

its like a retard convention in here. Gear oil is for rearend gears, i never saw a post with him saying he needed to change rearend gears. Mercron tranny fluid is what you need or GM syncromesh can be used also. Just drain the damn thing, pop off the shifter and pour directly into the tranny. About 3 quarts. pull the fill plug and stick your finger in there, after 3 quarts you should feel some fluid at your finger then you are good.

 

+1 .. ahahaha, this is quite the old thread but i felt i must 2nd that after thinking the same thing after reading the 1st few posts

 

:****

this thread is definately getting confusing. lol

i just went and checked my owners manual

FORD MUSTANG GT 4.6SOHC:

5-speed manual transmission: USE MOBILE 1 SYNTHETIC AUTOMATIC TRANSMISSION FLUID. 3.8 LITERS, or exactly 4.0 quarts.

this is the correct answer and it is exactly what you should use, it is straight out of the owners manual.

 

Yes this is correct 4.0 quarts . I think I will go with mobile1 synthetic atf since I run mobile 1 synthetic in the motor. Thanks

 

its like a retard convention in here. Gear oil is for rearend gears, .

ahahahaha,... well said

 

Not to confuse anyone but you can use RP's SynchroMax transmission fluid. Its specially formulated for manual transmissions.

 

Well im about to change out the fluid today. Any tip or suggestions? Im just going to drain it and fill by pulling off the stock shifter, but do I need to buy silicone(to seal shifter) after I put 4 quarts of tranny fluid in it to prevent leaks? Or am I ok to just bolt everything back and call it good.?

 

I was made confusing by one mistaken poster... That's all. Everybody makes mistakes.

 

How many quarts? I dont have a manual

i didnt have a manual either.... get a chiltons man 20$ at auto zone... it can be your best friend

 

Actually, just do an online search... There's a new spec on the fluid level that will help with the shifting problem (hard to shift into first/reverse sometimes). It's part of the "solution" from Ford's TSB...

 

Synthetic ATF. If it's a 3650, Mobil 1 or GM Syncromesh is ideal. According to Ford's TSB, 3.0L (think that's about 3.2 qts) on the refill. That extra 1/2 in of fluid will cause shifting problems b/c it will drag down the syncros. Easiest way to change is to drain with the bottom plug, pull the shifter and fill there. Yes you will need some RTV to seal the shifter.
