Weird Problem with Tranny and Speedometer
awhile back, i did my gears and put in 3.73s. well the needle on the mph starts bouncing like crazy once i get up to 55 mph and higher, everything below 55 mph stays steady. so i got my gear ratio changed and figured it would go away, but it hasnt.
here is the weird part. when the needle is bouncing(usually on the highway), if i shift the car to neutral, it stops going crazy and stays steady. i have no idea what this problem could be. anybody know??
