ATF or SAE 30 for velvet

[mark123456]

I currently have ATF dexron 3 in my velvet 72c and I find it shift very hard, with a loud bang, especially to reverse. Would switching to SAE 30 help this, I was thinking it may let the clutch packs slip a bit. Is there any adjustment that can be made. I have it between a cummins 210 and a Konrad 520 drive and recently broke some gears in the upper and think this may have been part of the problem.

Sorry about the response delay

Your velvet drive should have Dexron III for a direct drive and Mobile 424 if it is a reduction drive. Look at your tag and if it other then 1:1 you need a complete flushing out of the drive.

It shouldn't bang into gear, what is your idle RPM?
