Will not shift out if low from time to time
SOURCE: 1991 geo metro rough idle
i have no idea about an idle up solenoid relay but i had the same problem.. there is a hex screw on the motor that takes a very small allen wrench head where you can adjust the idle from there. its near the throttle body
SOURCE: geo metro transmission slips and
Auto Trans I had to replace solenoid in transmission there are two of them when you drop the pan. After testing with a 12 volt battery one was bad replaced and transmission works fine. Mine was a 1996, cost about $90 for solenoid.

Try this
Here are the most common causes of surges, stalls at stops, low erratic idle speed, rough idle and engine hesitation, it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

may be low on fluid as that wont shift the pistons in the valve body of the transmission
due to no fluid pressure!
SOURCE: 93 GEO METRO WONT START WHAT DOES DIAGNOSTIC CODE
P0012 = "A" Camshaft Position - Timing Over- Retarded (Bank 1). Check the timing chain/belt. It must be loose. Must be replaced ASAP if it is indeed loose.
