1998 Prizm starts off in 3rd gear, will not use 1st gear unless you manually engage
I assume this automatic 3 speed transmission is electronically controlled. Is this controlled by the ecm or a power train module?
Sound like the power train module is defective. Can you swap yours with another one that works?
