Interesting Observation... G-56 cracks..

[roperteacher]

I was under my truck the other day changing my new 07's Manual trans fluid to Amsoil ATF4 and I noticed There were cracks on the surface of the Aluminum housing. Little ones like you would see on tires that have been sitting in the sun for a while. . No leaks or anything, just a curious observation. . I cannot remember seeing them on my 06 G-56... any ideas? Just curious...

Thanks to John Holmes at Carson dodge... . He exp;ained the cracks as absolutely normal and it is a result of the SAND CASTING process! Interesting!!

Yup mine has the same things on it!

 

[SNoyes]

Yep.



Got those as well. Glad someone tracked down why they were there. I had the initial reaction like there was something wrong. Of course, I only started to look there when I had an noise issue from my transmission...

My 06 has the same thing. I believe it to be from the casting process.

They're not cracks, they're character marks.

while i have not seen the g56 housing, i have seen lots of cast aluminum components, and i am pretty sure what type of "cracks" you are talking about on the surface. . they are normal. . i have seen some cast components at work that have hundreds of small cracks on the surface, but a quick touch with the sander and they are gone [i got bored at work one day]

A polished trans housing would be cool.

roper, Did you give up on the 06? Did they give you the 07 since they could not fix the water leak on the 06?
