1993 eagle talon changed transmission automatic will not upshift stays in one gear even if you take gear shift to 1 or 2nd no change goes forward in drive wont up or down shift?

Check the ECM(ECU). They are know to have bad capacitors 89-94. Alot of people think it's the trans but it could be a blown capacitors. Blown cap's will make the trans only drive in lip mode.
