Speedo and cruise would not work for 2 miles?
I was driving down the freeway at 60 MPG and my speedo, odometer and cruise control stopped working for 2 miles. Then it all started working on its own. Is my VSS starting to go bad.....what else could be the cause of that?

Dodge had a TSB out regarding another potential cause of this problem. It was first noticed on the 4X4 but also applies to to the two wheel drive series equiped with Getrags.
The drive gear for the speedometer is sandwiched between two spacers. The spacers are held in place by the yoke nut at the back of the trans. You need to drop the drive line at the back of the trans and tigheten that nut to a 290 lbft torque reading. This is the only thing that keeps the drive gear from sliping on the output shaft. This can also cause the problems you describe - I know it happened to me. I have posted this on several posts on this forum and on other 1st Gen sites and it has solved more than a few speedo related problems on G360 equiped trucks. The nice part about this is it's free - just takes a little bit of your time.

try cleaning and tightening your electrical connections at the VSS first and IF that doesnt solve the issue, try Bobs suggestion.. I always like to try the simple/easy things first...

Ok, I had a few minutes to check it out. Wiring connection is very snug as well as the VSS/adapter. I will disconnect and clean out the terminal tomorrow. I agree, try the easiest possibilities first. If this becomes an intermittent issue I might replace the VSS first before looking into that TSB described, nut issue. My torque wrenches don't get even close to 290 lbs of torque. Heck, the torque spec on my dually 5/8 lug nights are 350 Lbs and that gets addressed with a 4 foot handle special torque wrench the Les Schwabs shops have LOL. Not sure where I could even procure a torque wrench for that spec locally.
