99 Suburban transmission leak?
Hey gang - it's been awhile.
So, after all the ice and snow here in Oklahoma, my wife noticed the Suburban leaking something.
Looks like transmission fluid - clearish and oily....
I crawled underneath and took a look, and - well... I admit I'm no mechanic.
It appears that there's somthing that goes into the bell housing - if I didn't know better I'd say it was a starter - cylinder about 10" long, no wires - and it looks like a seal is leaking where it goes into the bell housing of the transmission.
Take a look at this pic I attached...
What the heck is this?
Why is it leaking?
Is it a big deal to fix?

Well that is your starter. The color of the oil looks like it's the engine oil. I'd presume that your engine's rear main seal is leaking. As far as fixing, if the truck is 4WD then the engine would need to be removed, or the front axle would need to be removed to be able to get the oil pan off, and replace the seal. I wouldn't say it's an easy job. sorry

Well - heck. I guess the wires go in from above....
It is a 2wd, so does that possibly make it easier?

What engine is in there? It looks like a 454 from the limited view of that pic.Patrick

Could be oil from the top of the engine just working its way down to the starter. I had a quicky lube change the oil on my Silverado once and they spilled oil on top of the engine. The oil pooled there and slowly oozed its way downward. At first it looked like the oil filter was leaking. Quicky lube checked the filter for fit and then wiped the excess oil off the filter housing. The next day the filter was covered in oil again. I took it to the Chevrolet dealer and they found the pool of oil on top of the engine. Once that mess was cleaned up the leak was gone. Goodbye quicky lube, & thanks for the no-service.
You may have an intake manifold leak or something like the oil pressure sender could be leaking. Let's hope its not a rear main seal, because that is an expensive repair.
PS If the source of the leak is not obvious, you can add a fluorescent dye to your oil to help pinpoint the leak.There is no way to happiness....happiness is the way.:yipi:
