2002 Wrangler sport with automatic. Just had the transmission totally rebuilt and Transmission solenoid and Switch (Stop lamp) were both replaced. Problem is when car is in drive, you cannot depress the button on the shifter to downshift to 2nd. If you just touch the Brake pedal, button moves easily. Rebuilder say it is a control cable with an interlock in it, needs replacing - Jeep dealer says no (they want $135 to determine what the problem is). Everything on transmission is perfect except cannot depress Shifter button Any ideas?
