th400 speedometer help Hey guys, I am trying to install a speedometer on my th400. I want to hook up an autometer gauge with a cable to keep it simple. I am running a ford 9in with 5.14 gears and 35in tires. What do I need to get to do this? Thanks so much for the help.

You need a 15 tooth drive gear, 44 tooth driven gear. A drive gear clip, a speedo gear housing for a 44 tooth gear, an o-ring for it, a retainer, and bolt.
You can find it on tciauto.com, or patc. Or google search GM speedo gears and take the part numbers to your GM dealer.
Count what parts you have first, you might have a few of them already, maybe even a gear.
