I just purchased my dream car from some bouncy college girl who had a nickname for the car...The Millinium Falcon. I should have figured out the clue that Hans Solos' star ship took a while to make a light speed jump. Ok well here's the facts: My Supra's speedometer does'nt work, the o/d light blinks like a beacon (no o/d) the kickdown works below approx 40 mph, but shifts from 1st to third only, and my cruise control main pwr switch doesn't light up (or function).Now manual shifting is okay so I dont think it's mechanical, any ideas on solving this? thax
