Hairline cracks in an R154 Bell Housing?

[Rennat]

So i've been cleaning my transmission today, and i noticed that there are a lot of little hairline cracks and such... i understand that its 18 years old (i have a '90) but, im just being cautious and would rather ask the question then pay for it later on.

I'll go take some pics right now...

those are not cracks...those are casting imperfections from when the aluminum was poured or injected into a mold.....the outer side cooled a bit quicker causeing fractures on the outside skin so to speak but then got filled back in with aluminum....you can sand those out or file them out if you like...but they are just from the casting operation....i work alot with cast aluminum at work and see that very often! its no big deal...just take some heavy sandpaper to it if you care.

hell yes! like i said, i would rather ask a dumb question and learn, then not ask the question and pay for it!

i might go paint it... but not sure yet... lol

sounds like work....i just like to clean them up like new....i cleaned my trans up spotless and when im under the car it just look pimp all new lookin lol....i did toss the idea of painting but then again "sounded like work" so i said fuck it.

paint is easy... especially when you clean stuff with brake cleaner! lol

its most likely not going to get painted or anything, i have enough black in my engine bay...
