if its overfilled it can leak from the little valve on top.

mine use to leak from the rear tail part, where it seals to the main case, but after I swapped out the speedo gear, and re-sealed it, it doesn't leak at all anymore.



check your fluid level, and be sure its not overfilled first.

 

We changed fluid when it was out of the car. I will check to see if everything is tight and not overfilled.

 

Speedo gear assembly leaking is a common one and an easy fix. A T5 will also appear to "drip" from just about any oil leak in the engine that runs down and blows all over it like the front or rear seal, oil pan, oil drain plugs, PCV, rear of the lower intake, valve covers etc..
The trans fliud is red and the oil not but when it is blowing around and dirty, you'll only know for sure if you clean everything off and monitor for the source.

 

You are correct! When I had my oil drip from awhile ago it was EVERYWHERE under the car all the way back to the rear end!

 

shifter, front seal, rear seal, fill plugs, vent, where the tail shaft meets the gear box, and the speedo sensor. Those are about the only places it can leak.

 

I finally got under it today and found the allen head that holds the speedo gear in the trans was 3-4 turns out and it was loose enough for me to move a little with my hand...

Could that have caused it?

I get a few drops of fluid only on the drivers side directly off of the trans support...cant tell where the hell it's coming from.

 

yep. and all 3 of my t-5s have had a very slow leak at the seal where the driveshaft goes into the tranny

 

that seal looks good, we replaced all that jazz when I got the Ford Motorsport Aluminum driveshaft...whatcha know abou that son???

 

all mine looked good too, but still leaked a tiny bit:humpnana

 

Did it leave a spot overnight under that part?

 

A lot of people forget to clean and lube the driveshaft yoke when installing a driveshaft and that typically results in a seal that doesn't seal all that well.

 

Mine leaks from where the tailshaft meets the driveshaft when im parked on a incline.

 

still leaking!!!!

I got a few pics...not sure if they help or not...any thoughts....

 

if you can see the black trans support it seems to collecting on there and dripping off that on the drivers side...

 

looks like its coming from the speedo sensor. i think 90% of T5's leak from there man.

 

everything feels tight in there but it does seem like now that I cleaned everything up and checked again, it is coming from the sensor...

what is the best way to stop that sort of leak?

 

With a new one of these, they are under $20. You can try to replace just the orings (one for the cable and one on the body of the sensor) but that didn't work for me and I finally just swapped the whole damn thing.

 

where did you pick that up at?

 

Autozone house brand, $16.
