I assume that you have checked the fluid level and that is not the issue! This sounds like a valve sticking in the valve body or faulty shift solenoid. It could also be the vacuum modulator. Pull the vacuum line off the modulator and see if any transmission fluid drains out. Also check the vacuum hose to the manifold for leaks. You need to take the car soon, to a reputable transmission shop, that advertises "free diagnostics" and have the trans scanned and pressure tested. Do you have any codes or SES lights?
