06 F350 VSS Speedometer not working

alandells · #1 (**permalink**) 04-29-2010, 06:18 AM

I recently purchased a used 06 F30 6.0 dually and the speedometer intermittently works it doesn't work most of the time to be honest. I was told when the bought the truck the speed sensor in the rear end was replaced but didn't fix the issue. Is there somewhere else I can look or something else that might be leading to this problem? Because of the speedometer not working I can't use the cruise and I have a heavy foot. Any suggests would be greatly appreciated.

Thank you
A

My 06 had two combo meters replaced for this issue. I think there is a TSB for this IIRC

Okay what is the TSB and the IIRC? Also where are the combo meters located? By the Speed sensor? THANK YOU SO MUCH!!!!

The combo meter is the whole guage cluster.

TSB- Technical Service Bulletin
IIRC- If I Remember Correctly

Perfect. We already replaced the guage cluster. I will see if I can find any TSB. Thanks again

I have the same problem with my 2005. I replaced the transmission with one out of an 06 and the speedo quit working. I have replaced the speed sensor on the top of the transmission with the one out of the 05, didnt help. I replaced the instrument cluster and the sensor on the differential, still the same. I talk to the parts guy at dealership this am and he said it shows 2 sensors on the transmission. One on the tail shaft and one on the top of the transmission. I am ordering both today and let u know if it solves the problem.

Replace the one on your rear axle before you replace the other two.

Also check the ABS fuse
