Ford 640 trans fluid level

moday · Nov 21, 2022

I had drained the trans fluid during a rebuild....I'm assuming the square plug at the rear bottom left of photo attached is the fill level to use (see
picture below) and it's not the hex bolt behind the brake pedal.

Please confirm as it's not real clear where the arrow is pointing to in my service manual.

thanks in advance, Moday

The square head plug. Not the hex or will be removing shifter to realign forks.

THanks....that's what I thought as I saw another hex bolt on the other side.

I know there is a dipstick for hydro but I need to check axle. I can't honestly recall if I drained that....another square plug on same side in back?

thanks, Moday

Way at the back on the left.

On our 641, the rear axle check plug is a similar plug, toward back of rear axle, but on the other side.
