had similar prob. after blow a seal on my torque converter. turned out to be dirty connections on the sensor relays. clue was it was missing gear shifts. - arturo08
Sure does sound like the lockup solenoid to me! You need to fix the speedo. first. Any trouble codes? - pushrod
could have a bad tcc solenoid - goodguy
