OH!! Ok I see. Yes I have a manual. And yes, then my clutch fluid is very much filled a little past the fill line.

So in order to change the transmission fluid I would just need to unbolt the trans pan from underneath my truck, then bolt it back up and open the engine hood and fill it up with 5.6 pints of Mercon ATF? Where is the transmission fluid container (or tube that leads to it), like how can I identify it from looking inside the hood?

Thank you all so much for your help
