Ive recently replaced the transmission and it drives and shifts perfect, but sometimes out of the blue the car will die like the alternator is going out, usually within the first 5 min. of driving, lights dim slowly, no radio, no gauges, until the car runs rough then dies...the only way to get it started again is to jump it, otherwise it will just click like the starter is getting weak, and after you jump it, it runs fine and will stay running..The battery light flashes rapidly..doesnt stay lit, and i just put a new battery in. ive checked the grounds and all seem to be tight. I need help please!!!

    Make sure the terminals and cables are clean and tight even down to the starter, because a loose or corroded cable will cause intermittent problems.

    These cars are also very prone to burn up alternators. They will run with a charged battery, enough to get you say, maybe 100 miles without the headlights on, then go dead. I just replaced my alternator again to find out that the harness has now burnt out.
