I can maybe understand the possibility of the growl, but not the rattle under load. The rattle is due to the lash in the gear train and should only occur with the clutch out in neutral, NOT while driving under load.

I'm in complete agreement with Paul in thinking you have something going on besides the transmission.

BTW, I had the dreaded ZF "seizure" also and had Redline lube in the transmission with only about 2,000 miles. The transmission still had the original oil when I changed it at 59,000 miles & it looked like new oil when I drained it. I would not recommend Redline for the ZF. I've been running the Castrol from BMW in the new transmission.
