Default 2005 Outback Automatic transmission Issue

About a month ago I bought a 2005 subaru outback with a blown motor. The previous owner drove it on a single oil change for 40,000 miles, the motor then developed a serious rod knock. I bought the outback in running condition, trailered it home and replaced the short block. upon starting it, it had some difficulties, wouldnt start. After playing with connections it finally started and ran fine. No dash lights, nothing. The next day after finalizing a few things i started it again to heard a weird noise in the transmission along with the area around the ecu and under the drivers dash. Now, the cruise light flashes, the check engine light is solid, listing 2 codes (p1714,p0700) and at a stop the "AT oil" and "AWD" lights flash. When driving it would shift hard from second to third and on the highway at 2500rpms would stutter between overdrive and 4th gear. after a bit of searching, taking it to the dealer and troubleshooting i decided to replace the Transmission control module. Just did that tonight and the light flashing problem still exists however it appears to shift smoother.

Known information-
40,000 miles on heads, and complete driveline
70,000 on short block
Cruise light flashes, solid CEL, "At oil" flashes when slowing down and both "AWD" and "AT oil" flash at a stop
Replaced TCM
Check harness and connections

Codes-
p1714- Throttle position sensor power supply circut
p0700- transmission link


Can anyone help? im mechanically inclined and am stumped with this one.

The p1714 is your problem. This is the tps power wire for the transmission. The p0700 is a transmission system malfuction code caused by the other problem. This should be posted in the transmission section.

The p1714 is throttle position sensor circuit for the transmission so I would try that first.

You should check the connection from your shifter to the transmission.

unplugged the battery for 25 minutes, pumped the brakes, started it up and it was on.

Well I double checked that code on all data last night and it says it's your throttle power feed to your tcm shorted to ground or poor conection. Alldata says its the throttle pedal pasition switch but I think it would be your throttle position sensor.

I just bought one last night, read the same thing. Going to go through the steps and try to figure it out.

Chase the TPS wires back to the ECU, crack open ECU and look at the connections on the boars.
