This is my first attempt at a post, I have read everything I can find related to the 5EAT problems on this forum and thought I would see if anybody can help me with my issue. The car is a 2008 OBXT Limited with the 5EAT. The original symptom was that the transmission would not down shift out of 3rd gear when coming to a stop and then stall (similar to leaving a manual trans in 3rd and pushing the brakes without pushing the clutch thus killing the engine.) I took it to the local Subaru dealership and they found code P0741, performed a transmission re-learn, reflashed the TCM and noted that the turbine speed sensor harness plug had some damage. I elected to NOT replace the sensor harness at that time and drove off. The transmission acted normal through town and out onto the highway but within 40 or 50 miles (I am 70 miles from the closest dealership) the code kicked on again and the car went into safe mode. At this time, however, the torque converter didn't stay locked when I came to a halt. I called the dealership when I got home, cleared the code P0741 with Free SSM, and it drove fine for another 50 miles before going into limp mode again. This time, I decided to replace the entire sensor harness (the harness has all three speed sensors on the outside of the transmission, and connects to the valve body inside the pan). I also drained and refilled with 8 quarts of Valvoline Max Life ATF (I know many of you don't like this ATF so please let me know if this is part of my problem) and put in a new battery. After the new sensor harness, new battery and new ATF I took three test drives on 3 consecutive days. Day 1: 5 miles mixed driving without problem and normal shifting. Day 2: 10 miles mixed driving, slight rev between shift 2-3, got home added 1 quart of ATF since dip stick showed low. Day 3: 30 miles mostly highway driving with normal shifting, then the car stalled at a stop sign. I limped into a parking lot and the car died every time I tried to engage reverse or drive. The engine began to idle very rough when I started it a couple of times and after 10 minutes of Start-shift to R-stall, Start-shift to R-stall, Start-shift to R-stall, it finally stayed running and I was able to drive home. I made it into the garage, checked the ATF level - it was good, checked for codes - there were none. Waited for 1 hour and took it for another drive around the neighborhood and it acted totally normal. Now I am scared as @$%! to drive it anywhere because I don't know if it is going to die at an intersection when I stop. It seems to me that it is acting up when the ATF finally gets hot, after 30 or more miles of driving. I do have Free SSM but have limited knowledge of what to check for - any advice would be awesome!
