Just bought a used '07 Ultra Classic. Drained the tranny and got a pink/red milky fluid out? It's clean but doesnt look like any of the oil I am used to using. Not sure what previous owner was using. Anybody have any ideas?

 

Tranny ... or primary? If its the primary ... its most likely automatic transmission fluid.

 

Its the tranny and I dont think its tranny fluid. It is red but its milky, not clear.

 

The shop may have put redline oil in the tranny and after a wash a little water has made it's way into the tranny causing a milky film. Drain and replace oil with your choice of dino or synthetic. The other is someone used a 90/140 hypoid truck oil. Your trans should be fine.

 

Redline gear oil. It's supposed to look like that. I haven't used it but other's here swaer by it.,,

 

Thats right, Redline is dark red and a superior oil in my opinion. There may be foaming when it's hot but any milky color is usually an infusion of water.

 

Thanks big kahuna. I think thats what it is alright. Checked around a bit and saw it refered to as pepto bismol, and thats exactly what it looks like.

 

Redline shock proof heavy looks like pepto, but it won't help with indigestion, heartburn, upset stomach, or diarrhea.

 

It is redline shockproof heavy 75w250 gear oil. Very thick super high moly content and will last 20,000 miles easily.
