Hello, Am going to change filter in 85 700-R-4 . How much fluid should I expect to add back to Tranny to top it off again. Am also thinking of topping it off with Amsoil Super Shift synthetic . Any one else out there tried this, and what did ya think? Comments? Also, what is total capacity of that tranny ? Thanks in advance!

 

3-4 quarts, just add some and check it, then add some more till it's on the mark. amsoil makes good products
