Speed sensor ?'s

So i got the dual cases in the truck. Using gear drive cases. I ordered the VSS adapter from TG. It converts the mechanical signal to electronic. On the first drive the speedo worked for about a mile. I pulled it all back off to ensure that it was all splined in. Drove it again, worked for about 1/2 mile. I had to use the extended speedo cable adapter because I cannot fit the adapter on the speedo drive because of the FROR crossmember. The only thing I can think of is that I have a bad VSS adapter. Ive looked around and cannot find any issues with them.

 

I don't have any experience with the TG adapter, but i have the inchworm version and have had zero problems with it. I actually have another billet housing thing to make your own adapter if you cant get the trail gear one to work. Let me know if you want it.

Im using the same adapter @tlevan03 only it was from Marlin, they both look the same but price differs... havn't had an issue from mine for a few years now. Double check your connections?

Marlin's site has a testing procedure that might be helpful.

Same here... my Inch Worm VSS has never given me problems.
Be sure to use heat shrink on the connections if you need to cut/ add wire.

Good luck.
