My message is don't fill it up cold tsk I use a thin small screwdriver or something similar to check the fluid levels now, I use to use my pinkie finger but that gets old wiping the goo off of your fingers shruggy


This makes sense. The odd thing is that while I did top it off cold, I also checked it this time while it was cold as well. It was a hot day but the car hadn't been driven in several days...

Since there was some oil coming from the axle vent, I am guessing it can't be too clogged. The little crimped cap on it moves around freely.



I had an 01 Chevy PU I purchased new.. ( miss that truck) When doing the first service on it the rear fluid was supposed to be 1 inch below the fill plug, per the service manual... Thought this was odd, but it makes sense after reading this post....
