Hi Scotty. 2008 Saturn Aura. 180k miles. automatic. All these problems seem to be happening at the same time. All the gauges start acting up. Sometimes will not even turn over, security light comes on. Sometimes will start with security light on. Shift into reverse and hits hard, put it in drive but acts like its stuck in 2nd gear.  But then sometimes it starts perfect, shifts smoothly into gear and takes off normal and the gauges are fine. I put it in shop they tightened some cables at battery, did fine for a day then started having all the same problems again. Could this be an electrical issue causing all these problems and transmission problems at the same time? Thanks
