Yeah it could be the trans during highway speeds. Its fun! heck of alot of fun and I think it is the only reason the 4.8 doesnt feel like a total turd. But ZF6 eventually and all my problems will be solved!besides the front end noise lol.

 

Plan on a body lift!!! And the zf6 is a bit quieter in some aspects but manuals are noisy period!!!

 

26095470-pn for high pressure valve it may have been superceded. I will diuble check in am.... Forgot to look this morning!!!

 

I think I would rather do tunnel clearancing than a body lift. Just to keep center of gravity low and not have my frame hang low. I don't like that look much personally.

When I do the swap I will be double or triple layering the tunnel with a dynamat like insulator and possibly make a cool cup hold/ low profile center console. I like quiet!

 

Here is one like i was talking about albeit on a 4.3.....
