on auto trans use royal purple Max ATF,on ur manual trans use Synchromax, and for ur diff. use Max-Gear 75w90

u can get anything of royal purple from any performance shop and or napa auto parts

If you e-mail me your VIN I can tell you what trans your truck has. Most newer GM Manuals use ATF. Others use Syncromesh. It would be best to be sure. You can also call your local dealer and give them your VIN.
