Archived NV-5600 gear oil level

[EODDEWEY]

Installed fast cooler on driver side. Do you fill the transmission level with the fill plug or to what level. The service manual doesn't tell you anything about refilling the transmisson or how to refill the thing. Help!! Trucks sittin in my girlfriends driveway and she isn't a happy camper.

I filled it up to the fill plug level

I just filled mine up to the fill plug level. With both coolers on mine, it took about another quart and a half of gear oil.
