Hey guy just stombled on your site looking for help here it goes. I just aquired this car the trans fluid was looking a little dark so I changed it yesterday to my supprise their were 2 drain pluges so I called a loca toyota dealer to ask about the differental drain. They stated both must be emptied and your year you only have to fill the trans and it will flow to the diff. Not seeing any other fill plug I did as instructed today I took it for a drive 25miles and a noise sounded like cv joints binding I crawled to the nearest autozone borowed some tools filled diff ect. Still gone. Can it be fixed? Or new trans? Also if new trans I herd I can put a 1.8L 4sp auto is this conversion simple? Please help me even the dealers don't know Geo.

Whoever told you that the trans. Fluid will flow to the differential is someone to avoid.

The differential must be filled seperatly. There is a fill plug on the back of the differential.

Your differential is cooked, they are expensive to repair, and they can lock up ( due to lack of lubrication) causing the case to crack.

Find a used transmission at a junk yard, you can usually get a decent one for $300-500.

I am replacing a trans. In a 1991 Toyota due to the same problem, the previous owner let the differential run dry. Found a used trans. From a 1992 Corolla for $350.
