Rust in the Transmission dipstick tube
I have recently got a 1995 GMC Jimmy and am trying to replace parts. I went to check the transmission fluid but when I pulled the dipstick out it had rust on it and I am concerned it is also in the tube. I don't want to check it too often because i am afraid that rust will get into the transmission and mess it up. Can anyone help me to figure out a great way to either get rid of the rust or replace the transmission dipstick tube? I have looked at Autozone, Advance Auto, and even O"Riellys with no help.
