Speedometer and Odometer Not Working Correctly On Allison 545
Posted: Wed Jun 22, 2022 6:58 pm
Hello freinds,
I have a question pertaining to my 1991 Safari Serengeti which I just bought. The electronic Speedometer and Odometer don't work correctly, when I turn the RV on the speedometer goes from 0 to 15mph without any acceleration or even movement and when I turn the RV off it goes back to 0. The Odometer sometimes spins too fast and sometimes doesn't spin at all.
Shifting feels good through all gears, there is no slipping or jumping of gears. The only problem I can see is that the speedometer and odometer won't work. Also, I think there appears to be a cut sensor of some sort (which might be the transmission temp sensor) off the torque converter.
The transmission is an Allison 545 and it's an electric speedometer. Any thoughts or troubleshooting advice would be greatly appreciated.
Cheers,
