Hello, Im in the middle of replacing a clutch. This is the 1st clutch I've done. When I cleaned the insde of the transmisson housing. I found what looks like cracks but may just be seams in the aluminum. The dark areas inside the cracks just appears to be a little dirt. It doesnt appear to be transmission fluid. Can anyone tell me if I should be concerned? Thanks, Ray Note looks like I forgot to set the date on my camera! The pic are from today

 

Casting flash. Perfectly fine

 

I concur. If it was a crack it would have continued through the ribs. Not made a 90* turn.

 

Thanks I greatly appreciate the replies. Now I can finish putting things together! Ray
