Are the speedo gears and housings universal on these 904 trannies?
I'm missing one, but I'm not sure of the year on the tranny. Gracias |

Sorry, no, they are not. Gears are selected based on tire size and rear drive ratio. The parts manual lists the combos. Check with Kennedy American, they have a few listed.

The housings are the same but the driven gears are different. Chrysler's only have one drive gear which is machined into the shaft. Here's a calculator to figure out what driven gear you need with tire size and rear gear ratio. http://www.tciauto.com/tc/speedometer-gear-calculator
Here's a place that sells the gears and housing. http://www.transmissioncenter.net/speedometer_calibration_______va.htm |
