Just after the 2-3 shift I get 1.5* retard or less. I figured it was from the shift. But then I got thinking it doesn’t happen every time on the 2-3, and it has happened to me from a roll where I’m in third already. The speedometer is accurate ive checked it with two different radar gun. My question is since the timing for ½ and ¾ is based on speed, can my speedometer cable be an issue? Under normal driving conditions the needle bounces a little 1-2 mph, but it dose bounce really bad some time. I.e. cruse at 50 and it will drop to 30 and then snap to 80. Also what options do I have with my cable as to stop this?

thanks, Rich F
