1996 Geo Metro • 4 cylinder 2WD Automatic • 100,000 miles

I have a 1996 geo tracker with a 3spd automatic transmicion the trans just went blank while driving had to put in park turn off and back on so it would drive for a while and then it would go blank again. Changed the filter and worked perfect for 1 month and one day it went blank again. I have changed the filter twice and it works perfect for about 1 month and then again it go blank. Please help!

Sounds like something is plugging some of the miniature orifices. Try performing a full fluid swap. Also, have the codes pulled and let us know if any were stored by the computer.
