Question
1994 Cadillac DeVille - New speed sensor; put in new spark plugs & ratchet fell behind motor near speed sensor, found it setting on wire to speed sensor day later.  Now car is acting up, after approx. 15 min. of driving, speedometer goes to 0 & kicks out of gear, won't shift.  Codes are: 24-vehicle speed sensor signal to TCC; 75-intermittent vehicle speed sensor signal; 39-torque converter clutch. Don't know if this is relevant, but "old" speed sensor (4 mos. old) had metal shavings attached to it.  Can you please help us.  We don't know how to fix the problem.
THANK YOU!!!!!!!
