Need help.....pleaseeee
New to the group. Hope I am doing the format correctly. Sorry for the long post.
2001 Toyota 4Runner SR5 4WD
Issue : Popped these codes PO773 and P1780
Nothing happened for awhile and then when it started getting hot out the SUV would make some heavy clunking which you could feel while driving and then slip out of gear. When that happened the RPMs would rev up being out of gear. I pulled over and was able to limp it home in 1st gear. If I tried to go any faster it would slip out of gear again. The next day when it was cold in the morning I had no issues. Drove it to work. Then it sat in the hot sun all day and the original issue happened again.
So I researched the codes and figured it had to be P0773 which is the TCM ( transmission control module). I ordered a new one and replaced it. The same exact thing is happening. I noticed two more solenoids located next to the TCM when I dropped the tranny pan. I should’ve replaced those as well but I figured I would ask everyone in here their thoughts before I drop the pan again.
The P1780 error is a park/neutral switch code. This kind of makes sense because if I am driving and the car thinks its in neutral it would slip out of gear and the RPMs woukd go up. But then if I slow down why would that reset it and allow me to drive in first at lower RPMs?
On a side not. On the dash the VSC OFF and VSC Trac lights have been on for awhile as well.
Any information helping me solve this issue would greatly be appreciated! If I can provide any more information please let me know. I am desperate to figure this out. Sucks asking for rides everyday! Thank you.
