Re: Where is the speedometer cable located?

First off, don't place much faith in those road side radars.

You can try doing 60MPH and see if it take you 1 minute to from mile 
marker to mile marker.... but I put about as much faith in that as I do 
road side radars.

If you really want to know for fact, then you need to take your car to a 
pro who can slap the car onto one of those "road test" machines and see 
if the speedo matches the wheel speed.  We don't have these in my area 
since (luckly) we don't have state inspections [ie-another wheel tax].

Does the speedometer needle ever "float" between readings.  For example, 
if you are driving say 70-ish and keeping a steady pace with traffic, 
does the needle float back and forth between 60 and 70, or would it stay 
steady right there at 70.

If the needle stays steady right at 70 for my given example, then your 
sensor that is screwed into the top of the tranny is fine.  I have seen 
where the plastic gear that is pressed onto the diff cracks and then 
slips, thus causing the floating needle.  Only seen this on automatics.
