Hi, I have a 71 Cutlass with a turbo 350. It leaks trans fluid, I changed the pan gasket a couple of times and it still leaks. Doesn't seem to be leaking from the front seal. Is there any other areas it could be leaking from? Is there powder or something I can spray on the trans to detect where the leak is comming from?

 

Can leak at dipstick tube, shift rod port, speedo fitting. When you have a leak above trans pan it seeps down and could be mistaken for a pan gasket leak. You need to use something like brake clean to remove what has leaked (make dry) and then carefully check after sitting to see what becomes wet with trans fluid.
