Safe to put in Mercon V in A833?

Can use but do not recommend.Go with gear oil not auto trans fluid for an a833 in my opinion.
85/90 in gl4 blend with no modifiers. Newer gl5 gear oil has friction modifiers that are not good on syncros. Get my sta-lube at NAPA for about $35 a gallon. An 833 takes about 3.75 quarts.
