Ihave a 2002 toyota echo it does not shift into overdrive plus it does not idle properly

SOURCE: I need to find the pattern for the serpentine belt on my 2002 toyota echo

Did you check under the hood? There should be a decal w/ the proper routing of the belt somewhere in or around the engine compartment. If u can't find it, let me know, I'll try to get more info. countrycurt0

The one labeled "ACC" in the interior fuse box

SOURCE: takes a long time to shift into overdrive

sounds like the toque converter is locking and unlocking have the trans serviced and flushed if this does not cure the problem then you could be looking at a trans rebuild or replacement.Check the fluid first could just be low.

SOURCE: 2000 toyota echo, transmission won't shift to 4th

With such a small engine, the automatic Echo won't shift into overdrive (4th gear) until a certain engine/transmission temperature is reached. This is to protect the bearings and gears from too much torque and stress while the oil is still cold and not flowing at it's optimum level. Usually when the blue "cold" light on the dash shuts off, the transmission will up-shift to 4th. When it is very cold, it could take another few minutes of driving before it will do so.
