I'm having a problem with my transmission in my 94 z28. It doesn't downshift at all unless you manually shift for it, but it still upshifts perfectly fine on its own. Does anyone have any suggestions on what to look for. A friend of mine thought it could possibly be a vacuum leak. Would that be a possibility? If you have any suggestions to try before taking it to a shop, that would be great. Thanks.
