Guys, need your help. I have someone here locally that seems to have a bad vibration coming from the tranny at the time you would expect lock up to occur. The PCM was just tuned by Ed Wright and a Spohn chassis mount torque arm installed. The converter is a SY3500. He did not feel this before the PCM program was changed and torque arm installed. I know that Ed changed the way he programs shift points (RPM based instead of speed). We still need to a-tap the car to see where TCC is being sent to the tranny.

If I remember right, I saw this posted here a while back. Can anyone help?

A slight vibration may have always been there, but not noticed until the new poly TA mounts transmitted the vibration. How bad is it?

Did Ed change the line pressure?? Are his cruise LTRIMs negative? If those two are fine, have Ed raise the lock-up table by 3 mph if he left it stock and see if that works.

When are you going to get Edit and eliminate the middleman? <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />
