CODE P0713

Good afternoon , i swapped my replacement transmission.. everything mechanicaly seems ok, but it doesnt shift to 5 and 6th gear. the code that keeps popping up is P0713. anyone have any input ?? thank you

 

Any info would help.

 

Don't quote me…but looks like it a transmission temp sensor. May be locking you out of 5th/6th to protect itself since the ECM is getting bad info from the sensor.

 

The problem is ive searched and cant find the temp sensor for the transmission. Funny enough when running the trans temp does work .

At 8:20’ish …Looks like the temp sensor is in the valve body (assuming you have an AB60 trans -you can confirm on drivers side door VIN sticker).

Hopefully someone can chime in for further but doesn’t look like a tough DIY job.

 

that helps a lot! thanks ... hopefully thats all i need to replace

 

Any update on this?
I just sent my truck in for a trans rebuild. They completed the job and the trans was shifting beautifully. after 1 day of driving, I get the P0713 code and it won't shift past 4th gear. I take it back to the shop. They put on 3 different wiring harnesses and 2 different valve bodies and still have same issue. It is now worse, they clear the code and then the code pops up as soon as the key is turned on a cold engine. They are afraid there is a wiring issue in my dash between ECM? and trans temp sensor. Coincidentally, for the past few weeks before I took the truck in, I would have intermittent issues with some displays on my dash (the clock wasn't displaying, the radio display was off but radio worked, and one more display on my dash). I have now been without my truck for nearly 4 weeks and they want to keep it for 2 more to try and find the wiring problem (or possibly PCM, ECM issue)
If anyone can help me, I would greatly appreciate it. Thank you

 

i feel you pain , basically the same situation i am encountering . Mine still hasnt been fixed . If i clear the check engine light it comes back right away . Please let me know if you figure out what the problem is . Also which harnesses were swapped out ? Thank you

 

Its probably the solenoid that is bad. I'm not saying I'm AAMCO nor a transmission specialist, but if you get an immediate code, odds are its not a harness, unless it was burnt or melted. I had a bad solenoid and the code would pop up immediately after I turned over. Something to ponder about.

 

I will tell my mechanic about the solenoid. I did originally have a code for a bad solenoid D in the tranny. That's a good idea to check if they did in fact swap it out.

The wiring harness is, I assume the harness that connects to the transmission. I believe the temp sensor is part of that harness. Since multiple harnesses still have same code, it must be something else. I will update as I learn more.

 

Do you remember what solenoid it was?

 

solenoids were changed out with the valve body so I guess it isn't that.
I've read on other threads that it could be:
1. corrosion on harness connectors or broken/bent pins. (checked this already)
2. Faulty thermostat or coolant temp sensor (apparently the trans won't shift into the higher gears if it thinks the engine isn't warmed up)
3. bad ground or low voltage on battery.
4. faulty wheel speed sensor. (I'm curious about this one because I do remember my traction control acting up before I took to shop)
5. wiring to knock sensor

 

Im completely lost with my trunk. everything worked perfect prior to the tranmission swap (minus the slipping) on the cluster it shows that the engine temp works, transmission temp works, i have a brand new battery the connector wires and pins are in good shape . the only thing i havent changed is the temp sensor in the transmission. also i believe the wheel speed sensor works because when i drive it ... it shows the mph clock working.

 

I get it man, mine was actually working fine, I just saved up the money and knew I needed work. My main issue was my torque converter but I drove it like that for 3 years. My mechanic is on vacation this week so he will get back to it next week. I'll let you know what happens.

 

Hey Rambarani, my transmission guy borrowed another transmission and swapped it with my rebuilt trans and still got the same code so it can't be anything in the trans. He traced all the wires back to the PCM/ECM so he thinks the issue is there. We found a used one for $300 (new one is like $1500). We are going to swap them and see if that is the ticket. It comes in next Wednesday so I will let you know.

 

Hopefully you get a decent outcome. I'm trying g to help someone who's code won't go away after a rebuild.

 

Whats up man , any updates?? Im still trying to figure mine out too

 

Finally fixed it! It was the ECM/PCM. Its the little computer on the passenger side firewall. It has a plug with about 60 wires going into it. My transmission guy was convinced it wasn't anything in the transmission and wanted me to replace the ECM. A new one was like $1600 from Toyota. Since this was a guess at the solution, I suggested getting a used one from a junkyard and see if it fixed the problem code. The first ECM we got, it made the truck throw the same P0713 code plus added 3 more codes for the throttle body. Sent that ECM back and got another used one. Once this one was plugged in and programmed, the problem went away. I have been driving for 2 weeks now with no issues. We don't really know why this happened and whether it was a previous issue or not. I did mention that my dash clock and radio display were not working. Now they work so it makes me think my ECM was glitchy. Good luck!
