Hey guys I have a T10 in my 78 Malibu. I had 4.10 gears for a very brief period and the speedo worked but was off. I swapped to 3.23 and it stopped working. I determined it is on the transmission side as a drill turning the cable on that end, allows the speedometer to work. Could this be something like stripped speedometer gear? I see a kit on ebay with 5 different gears and a bullet, what exactly is the bullet and will i lose fluid when i pop the gear out?
