Manual Trans Oil Leak (major leak)

My manual trans seems to have puked up all of its oil...found an oil slick in the driveway. I smell burning oil. Today I started getting massive gear whine in fifth. Now I know where the oil is coming from. The splash shield is covered in oil. When I saw the dark oil, I thought it was engine oil. Most of the other Ford manuals I have owned used Mercon. Didn't see pink in the driveway. The Fusion Mazda G5M uses 75W90 gear oil.

 

Great fun. I just happen to be a transmission engineer...

Any clue as to what might have caused it? Bummer though.

 

 

Probably one of three things given the location of most of the oil...

 

1) Input shaft oil seal - but the clutch wouid probably get soaked with oil and I have not noticed anything strange with the cluch.

 

2) Leak between the housing and case.

 

3) Diff/axle seal leak.

 

 

I'm gonna take it in tonight. The dealer's location is about a 25 minute walk to home, so I can hit some bars on the walk back!

As long as your car is under warranty they should provide you a rental when they have to keep it overnight. That's how it worked when my Explorer was under warranty.

 

For Ford/Mercury a loaner is only provided for the first 12 months/12K miles. For Lincoln the warranty only calls for "transportation" but most Lincoln dealers will give you loaner for the full warranty period.

Yeah, perhaps...just hit 12 months and 11k miles. Ford dealers are given a "rental budget" each month that they can use at their discretion from what I understand.

 

 

The advisor said the tech reproduced the transmission noise (a deaf person could hear it) but the oil is from the engine. :rolleyes: The trans is being pulled and repaired - next Monday. The oil level in the engine after cooling has been at the same level for weeks - I check it often since I don't trust the stupid oil filter cartridge design - and more specifically, the o-rings. The oil on the splash pan has a strong odor, nothing like engine oil.

 

We will get a rental...my wife can bust balls pretty good. We bought/leased five new cars in the past three years, if they want our business... :hysterical:

Keep us posted. I'm sure many of us are curious about your episode.

Called the dealer...parts are on order for fifth gear. Maybe tomorrow I'll get it back.

 

The Edge is running $15 a day for the vehicle upgrade and unlimited mileage. Gonna go broke if they keep the Fusion much longer.

A new fifth gear should fix the noise (grinding) problem but what caused the leaking of fluids?

They claim a replacement trans hasn't arrived yet. In the meantime I am driving a stripped down turd of a Taurtus when my loaded Fusion is stuck in the dealer. No Alpine, no sunroof, no leather, no Metro Park sticker...if I want to use a Detroit area Metro Park, I will have to pay for a new sticker. This f&^#ing sucks. By the time I get the car back, it will be about 2000 miles under on the lease. And if I want to drive more than 100 miles a day on this Taurtus, I have to pay!!! :angry: :wacko:

 

The service advisor said a dowel pin on the flywheel went through the trans housing and did some damage. But, it did not cause the oil leak...as a transmission engineer, I don't recall a trans issue where the housing or case got pierced and didn't leak.

 

I spent a bunch of time trying to clean up the three oil slicks in my driveway with kitty litter yesterday. This is definitely not 5w-20 in my driveway, it doesn't soak up too well. Storm runoff from my 'hood goes to the Rouge River.

 

They are replacing the trans, clutch, throw out bearing, flywheel...

 

My wife is doubting another Ford lease. And I want out of the auto industry. My dad spent 30 years as a Ford engineer. Now he is getting screwed on healthcare costs and who knows what else they will pull.

Got the car back on Friday - March 2. New trans, clutch, flywheel, TO bearing...plus other warranty stuff. The new trans is tough to get into first and second when cold. But the trans is new, Ford doesn't reman manuals from what I understand.

 

The floormat issue - you get a whole new set when the driver's mat wears a big hole under your right heel. That is was nice.

 

The trim piece replacement on the door B-pillar did not fix my wind noise issue. The old piece fell off at 4k miles and I though the open hole was the source of the noise.

 

New front passenger wheel bearing - I found slop in the wheel and retorqued the half shaft nut. Apparently a lot of water got down into the bearing and rusted the hell out of it while the nut was loose.

 

Overall they did a good job on the repair. The only thing that feels different is the cold shifting.

Thats a pretty old trans design. Could require a little break-in or maybe manufacturing variance is an issue. Its a lease with less than two years to go...and warm weather is coming. Hopefully it goes away in the spring. If not, the next owner can worry about it...when it is out of warranty. ;)
