Output shaft seal leak

My 2005 GMC Canyon has a 5 speed manual transmission. The oil seal behind the transmission looks to be in good condition, but oil is leaking out of the drain hole in the seal. Is this a result of another seal leak inside the transmission housing? Or could this be a result of not driving the truck much? I usually drive it about once every 2 weeks.

IMMA JEEP CJ KINDA GUY

I ATTEMPTED TO LOOK UP YOUR VEHICLE IN "MITCHELL 1"

"CANYON" WAS NOT AN OPTION---PICK-UP "C" OR "K" 2500-3500 WAS. ENGINE SIZE WOULD HELP TO.I NEED MORE SPECIFIC INFO! (I LIVE AND BREATHE JEEP CJs, SO BEAR WITH ME!)

I ALSO ATTEMPTED TO LOOK FOR THE SEAL(S)? AT AUTOZONE. COM AND ADVANCE AUTO. STILL, NOT ENOUGH INFO

TO TRY TO LOCATE YOUR TRANSMISSION ELSEWHERE--IT'S #'s, WOULD BE HELPFUL

I SORTA SAID, "MANUAL TRANNY SEAL, HOW HARD CAN THAT BE TO INVESTIGATE?"

WITH THESE MODERN RIGS, LOOKS LIKE IT'S NOT SUPER EZ, AS WITH OLDER JEEPS AND TRUCKS

CAN YOU SEND MORE INFO?

MAYBE A GOOD "IN FOCUS" PIC?

WE TRY TO PLEASE, EVEN IF I GET STUCK, WITH MORE INFO, THE OTHER FELLERS HERE, MAY JUMP IN TO ASSIST

Thanks for your reply. Here is some more info:
The truck is a 4WD GMC Canyon Z85 SLE.
The engine is a Vortec 3.5L 5-cylinder DOHC.
The transmission is an Aisin AR5.
Here is a picture of the seal. There is a little hole in the bottom of the seal that I thought the oil was leaking out of. But now that I looked at it a second time, it does appear to be leaking around the shaft/inside of the seal. So I suppose it's time for a new seal? Thanks.

YOU MUSTA CLEANED IT UP?...I WAS GONNA RECOMMEND "PURPLE POWER"...SIT 5 MINUTES, RINSE WELL...KEEP IT OFF OF YOUR PAINT! THEN LOOK FOR THE INITIAL IT LEAKS.

THAT LOOK LIKE THE RIGHT DESCRIPTION AND PART???

LOOK THRU THESE...SURELY ONE OF THEM IS SIMILAR...DON'T STOP ON THE 1ST ONE....SOME OF THESE VIDEOS, ARE BETTER THAN OTHERS...YOU KNOW YOUR RIG, BETTER THAN I!

YOU KNOW YOU CAN DO THIS! TOOLING, SHOULD BE MINIMAL. A "MECHANICAL" PAL, WOULDN'T HURT EITHER.

YOUR THOUGHTS?

Thanks so much for your reply. This should be do-able.
Youtube is great for stuff like this! It really helps to see it being done- just trying to fight through my shop manuals can be a little confusing sometimes.
Thanks!

I'll plan on taking care of it in the next week or two and report back, hopefully with no problems.
I do like to watch youtube and get some tips when I'm tackling a new project. Even though they can take a few hours to download with my dial-up connection!
