I know its the solenoid switch stuck in l/r position i was wondering what that means?
I'm stuck in limp mode can do a key cycle then it shifts perfectly fine.
Things Ive already replaced:
TCU (turned off check engine light)
Input and output speed sensor (old output had metal shavings on it afterwards shifted good for 15 minutes then a rough downshift to 2nd and stuck in limp mode once again)
It was also throwing a p0700 code but now there are no codes any help would be much appreciated I have tried another shift solenoid pack but it was used and didnt do much good it shifted maybe 5 minutes then computer caught on please i need help
