Had tach jump problems with my '95 after the tranny was rebuilt and a new ECM installed at the same time; another ground wire solved the problem - but I think it was not a real solution, as after only 2,000 miles I need another (costly with labor) ECM. I think the tranny was rebuilt for the standard and not the autobahn package and it's electronically killing my tach and on-board computer. Hope this at least helps you start to troubleshoot.

The same exact thing happened to me yesterday, driving 65 then a slight pause/jerk, then the tach red lines but the car ran fine....have you found out anything?

You guys all need CPS (Crankshaft Position Sensors) replaced.
I just had it done - $164 - but my mechanic rocks and is not a thief.
Problem solved! And no more hesitation/missing on passing.

Just bought a 95 olds aurora, niether the the tach or speedo work. I know they are electronic with some sort of sensor on the tranny, but have been trying to find a fuse panel diagram to see if there is maybe a fuse or relay that can be replaced?

was this the fix
I have the same problem

had a 2001 aurora v-6, very intermittent, would stall and tach would jump. remove starter to easily access crank sensor. remove and replace crank sensor and problem fixed. sensor costs about 100.00 for oe replacement, mitchell calls 1.5 to r and r.
#11 of 12 01 aurora tac problem
Apr 26, 2010 (5:59 pm)
when engine gets warm, about 6 miles, i have the hesitation in the 3.5 v6 motor,
then tach jumps to 4-5x what it should read. motor stills runs fine most of time,
sometimes rough on restart, but smooths out & then ok. i will try the CPS, seems
to be a common problem on the 01 aurora 3.5

Sometimes when i shut my 1999 aurora off the gauges go wacko and also not often but sometimes the car will stay running for 2 seconds? Any advice would be helpful
