I put a 97 2 wheel drive 4runner automatic transmission in my truck and trying to find out what vehicle speed sensor goes in the tail shaft of the transmission? I need the one with the gear on it. I bought one from the junkyard that’s a 20 tooth out of 4by 4runner and it seamed like the gear was too big and wouldn’t go in. I pulled the gear out of the sensor and it went right in so that made me think the gear was too big so I bought one one eBay that was a 19 tooth and it turns out the one with less teeth is bigger the the one that has less teeth. Does anyone have any idea what sensor will work??
