Change the filter and fluid in your transmission. Your problem is caused by low fluid pressure resulting in poor torque converter lock up (shudder). Get the OEM filtran filter, 6 quarts of transmission fluid, Lucas trans fix, transmission pan gasket, and filter o ring. The fluid change steps can be found on this forum and can be performed in under two hours. A lot of guys on this forum use Redline D4, Mobil 1 ATF, or Maxlife. I've had great results with Maxlife (red bottle).
