Default Transmission fluid
can anyone tell me how to check the transmission fluid in my 1985 c4. I bought it in aug 2014. I drove it a little to familiarize myself with it. I saw a small leak between june - oct 2015. It seems to have gotten worse. The battery died shortly after so I need to get that resolved and begin the work to restore the few things that I know need addressing, but want to make sure there's enough fluid in the tranny to move it.

the only thing that I will add to Ant Farmers advise is if a Manual trans is Gear oil in the main trans (the T-10 unit the front trans) ATF in the O-D unit the one more rear, be warned the O-D units tend to smell like gear oil if not serviced regularly so don't be fooled. So if your O-D has black Stinky oil it needs a full service

I'd make sure it is at operating temp before I do that if it is auto.

Go for a 10 mile drive and check then. Make sure you are on level ground and check. I want fluid moved around, hot and see if the fluid is in good condition with nothing swirling around.
