Ive just had a yank ss 3600 stall and a tsp torquer v3 cam installed and dyno tuned. at wot the car is fine and the tune is fantastic,,BUT drivablility can not be properly tuned cus the car keeps fluctuating speed signal even while moving. At idle its vary evident cus you can see the speedo jump sometimes high as 40mph. Has any of you had this problem and or know a solution??? Tuner recomended checking for a damaged or grounded wire or possible a vehicle speed sensor. Any help would be great, and I thank you all!

I've replaced the transmission speed sensor but problem continues. mostly jumps in gear at idle but will jump as you put it in gear or even sometimes when you put it in park!

Any codes? You could try disconnecting the battery and letting it sit overnight, maybe its just a bug in the system. I had the same thing happen to me, was going 130mph in park lol. Battery out and problem hasn't came back yet.

I did try that with no success. Its actually getting worse. Jumping alot at idle.I will pull some panels over the weekend and check to see if wires are rubbed and or grounded out.

Wires got pinched when they put the trans back in.
