Where is the transmission dipstick located on a Chevy 350?

You will find whether you have a th350 transmssion or any metric trans , the dipstick will be located on the right side of the vehicle in the rear. Your (left hand side facing the engine) there should be a tube that comes up between the ac unit and the engine on the passenger side. its not going to stick out very far so it might be kind of hidden, but there is only two dipsticks, oil and Transmission Fluid,(process of elimination)
