I believe i have located the fill cap and when i remove it there is a dip stick on it. Is this the correct fill cap because i cannot find any other one.

Hi,

Yes, there is a dipstick under the cap. I attached directions below for draining and refilling the transmission. There is a picture of the dipstick.

Please take a look and let me know if it helps or if you have any other questions.

Take care,

Joe
