rear transfer case oil CAM OUT BLACK FRONT WAS MORE BROWN SHOULD THIS BE A CAUSE FOR CONCERN LIKE INTERNAL WEAR , THERE SEEMS TO BE A SLIGHT LEAK FROM AROUND THE REAR TRANS CASE I CANT PUT A FINGER ON IT. I JUST DRAINED BOTH T CASES AN PUT FRESH AUTO TRAK FLUID IN

 

Caps lock??

We only have 1 transfer case, the one that connects to the transmission.

The others are the front diff and rear diff. Both of those just take gear oil, like a 75W90 and will be brown/black when drained.

The transfer case on a 4WD non AWD normally just takes regular ATF/transfluid. The AWD transfer cases will take that special auto trak fluid. It's not abnormal for the T-case fluid to be colored if it hasnt been changed in a long time.

 

i put the auto trac fluid in the front diff then by mistake i havnt driven in 4wd since i put it in, . I'll just drain it n put that 75W90 in the front diff gesssh i fucked up
