:tttt:i have the factory trans pan on my truck and plan to do a filter change on it and was just wondering how much fluid im gunna need to replace what i drain thanks for any input :pca1:

try a search

If you're just draining the pand and replacing the spin on, you will need 2 gallon.

fyi, the internal filter doesnt need changing unless the tranny is re-built
