so here i go to change my oil, and i see a leak. fluid on the tranny pan is greenish (i thought atf was red). weird because it seems to originate from one of the bigger bolts holding the pan in. the tranny pan seal shows hints of oil moisture all around. tell me what you think, bc i'm not rdy for a new tranny, i just got new axles in, broke as a joke, and i'm ready to sell this car because of the hassle it's been.

1st pic - oil present on hoses on upper left corner
2nd and 3rd pic -
4th pic - whatever is b/t the tranny pan and the oil pan has some oil on it as well.





i'm hoping it's grease from when my cv's split open, but i'll let you guys tell me what it is.

 

all the green fluid is antifreeze. judging by the pictures i cant tell where its coming from. and the 4th picture if im right that looks like where the transmission bolts to the engine that that would be a rear main seal leak

 

uhhh rear main seal is to retain the oil in the engine.. not coolant..

 

is this something that i can get by the winter with? I guess I can just keep filling the atf up while it leaks??

 

if it's a rear main seal leak, that should be atf. but where is that coolant coming from???

 

I thought a failed rear main seal would cause an oil leak, that it was seperate from the tranny? I know the tranny bolts up there, but...

 

rear mains is to the motor, if left alone without repair, oil will leak out causing u to lose oil, while oil will smear on the Flywheel. The green stuff is coolant, and judgin by the amount and the "wetness" it seems rather fresh did u do any kind of service to it? maybe opened the cap and some spilled out.

 

the only recent work i had done was both front axles and both accessory belts.

 

its the rear main seal in the transmission. its where the output shaft comes out of the trans and the torque converter goes on that seal right there is whats leaking

 

by the pictures, it's the rear main seal.

fluid found leaking is green in color. is it my horrible luck that both of them have pooped out?

 

its the rear main seal... its a b.itch and a half to replace because you have to drop the transmission... dont worry about it much...

 

just go to a shop and have them look at it

 

Just to clear up a little misinformation here and to simplify things.

1 Picture of your radiator (duh) and atf lines where they flow to the radiator for cooling(the shiny metal lines). It appears that coolant from your radiator is flowing down the metal lines to where they bolt into your tranny and the coolant is then flowing off them and onto your pan bolts. You have a leak at your radiator somewhere it appears which is what the green fluid is telling you, otherwise, check your upper radiator hose and see if there is a crack/leak on it where it attaches to the radiator or elsewhere.

Naplesmaxima--there is no rear main seal in the transmission. The rear main seal is at the rear (side in our horizontally mounted engines) of our engine where the engine crank/output shaft is. The rear main seals soul purpose is to keep engine oil in the engine (im sure you already know this). The rear main is not part of the transmission though.

Many people have leaking rear main seals. Its not preferred, but somewhat normal to lose a little oil there and over the years, you will notice it where your tranny mates to the engine. If its not dripping, i wouldnt worry about it.

I would check the ATF in your transmission, but from the look of the pictures, you do not have any ATF leaking from anywhere. Situation appears normal except for the antifreeze/coolant that is leaking from somewhere near the top of your engine.

 

I agree with the leak coming from around the area of the radiator. Double check all of your Rad. lines, the upper and lower hose. Also double check the cooler lines underneath the rad.

 

the automatic tranny cooler is in the bottom of the radiator. it looks as if the coolant ran down to the tranny from the hoses, most likely the tranny cooler lines. you may have a cracked radiator, but it could be a back cap or over flow hose.

 

ok thanks. the coolant coming from a cracked rad/broken hose was sorta what i was looking for. I was planning on doing a coolant flush anyway, so I should probably just buy new hoses to boot. hopefully i could find something in the haynes to help me out. Thanks for the replies, that naples dude had me confused as hell

 

So what made everyone think it was the real main seal????

 

They dont know what the hell they are talking about. They see a leaky rear main seal and think thats his problem and completely overlook the fact that there is green liquid everywhere.

 

I dont know what everyone else is seeing but last time I check green fluid was coolant. Where you guys are getting rear main seal from is beyond me.

 

halloween does that to you. you see things that are not real out side, so you see things that are not real under the hood.

but seriously the only way that could be a RMS leak is if the head gasket is blown and all the oil already leaked out of the RMS and now coolant is following. no f'in way.

 

fill the radiator, and gently squeeze the coolant lines leaking to the engine. you should find the leak like that.

 

OK first of all like everyone else is saying, RMS leaks result in OIL leaks....Now, i see from the pics, there is green fluid everywhere....Maxima Radiators are tempered plastic, so it is just like glass (in the sense that if its heated and cooled QUICKLY it will split in some areas....example-Driving your car 400 miles nonstop then getting it washed and gettin cool water on the radiator can SOMETIMES make it split...) Now if u are leaking any dark thick oil, show pics of that, because that may mean u are leaking gear oil form the tranny....But as for the green stuff, its Anti-freeze coolant, so if u want to spare yourself the time, go to a valvoline quick oil change center and let them find it for 20 bucks...no big deal to find it for yourself though so good luck with whatever choice you make...BUT to completely clear up the BS on this thread as if previous posters have not done so already, REAR MAIN SEAL LEAKE WILL RESULT IN AN OIL LEAK!!!!!!!!!!

 

Referring to the last picture, that is a photo of where the transmission mates to the engine. The dark color generally indicates a slight oil leak that is seeping out of the mating surface, flowing along the inside of the bell housing/rear engine housing, and slowly seeping out of the mating surface where it mixes with road grime and gives a wet dirty appearance.

As stated in my post, the main problem is the leaking antifreeze, however, judging from the last picture, it appears there very well may be a seeping rear main seal which is pretty normal in fact, status quo for our cars it appears.

Slag

 

...Slag for the death blow!

 

good thing he doesn't have toyota red in there... would have been harder to tell

 

woudl it be hard to replace the hoses concerned with the coolant system? i'd love to be ghetto and put some duck tape on the leak or something.
