When going down highway I slowed down made a right turn n noticed the engine light and a flashing ! came on in my 2000 Taurus. I noticed it didn't change gears also. I've checked transmission fluid and had it hooked to a scanner. Codes are showing malfunctioning with transmission. Been told it could be ECM but also told it was speed sensor. Car runs fine, transmission goes into reverse, neutral park and car drives just won't change out of low so pretty sure it's not torque converter... Anyone else had this issue?
