Hi all. I have an 89' Toyota Carib which is the right hand drive version of the Toyota All Trac. It's pretty much a Corolla. Anyway, I have been having an issue with my car not going into overdrive. The temperature reads cold when I approach highway speed and it has the tendancy when the temperature drops off to nothing to shift back into 3rd gear. Here is what I know:
- its not a transmission issue rather its a safeguard for emissions that disables the car from going into overdrive when the car is cold. So, in reality my car is not cold, it just thinks it is. So what can I do to troubleshoot the root of this communication failure??
Any information would be helpful
