I have a 92 FWD Auto Trans Legacy that was missing a differential dipstick. I picked up a yellow one from the yard and filled it to the full mark. It is leaking from the shaft seal a little.

 

Today, I saw a black dipstick which was about 2.5" longer (about 11"). With it installed, the diff is 2.5" over filled.

 

Will someone with a FWD 90-94 I think check, and let me know which is correct. Thanks Larry

 

Yellow Plastic top Dipstick - straight shaft about 3/16" dia 7-8" long

Black Top DipStick - bent shaft with mid support 1/8" dia about 10-11" long

 

Thanks for the correct Identification!

I'll check for you when my wife gets home in her 90 FWD Legacy standard.

The yellow one is typically the atf dipstick.

 

My 90 FWD auto had a black handled dipstick for the differential. It's possible in 92 they changed the coloring and stuff.

I checked the yard yesterday. The 90 takes the long black dipstick. The tube sticking out of the trany is about 3" long for this longer black dipstick. The yellow one, the tube only sticks up about 1" or so.

 

This should fix my leaK :>)

 

Thanks for the feedback
