WHEN THE KEY IS IN THE #1 POSITION IT SHOWS THE CAR IS IN SPORT MODE WHEN I HIT THE SELECTORE SWITCH IT TURNS TO ECONOMY BUT WHEN I LET THE SWITCH GO IT GOES BACK TO SPORT MODE.THEN WHEN I START THE CAR UP IT GOES IN TO LIMP MODE AND NO DRIVE STYLE IS ON. WENT TO THE TRANY GUY HE TRYED PUTTING THE COMPUTER SCANNER ON IT AND IT DONT SEEE THE TRANY BUT IT DOES SEE THE ENGIEN.

do you see the S-M-E and the gear indicator in the dashboard?
If not, clean the gear selector switch and all is o.k.
Info how to do is on Gale's page

When I Turn The Key In The #1 Position It Comes On In Sport Mode Then When I Start The Car The S-e-m Go Off And It Is In Limp Mode. But When The Ignition Is On I Put It In E Or M Mode It Goes Right Back To The S Mode. Ill Try Cleanning It And See What Happens Any Other Posibilitys? Is That A Reason Why The Computer Scanner Doesnt See The Trany Computer Too?

I had it once that it did not go into S when switching to S.
The switch was dirty. I just switched about 30 times through S-M-E while engine was off, and it was o.k.
But while you clean the gear switch, clean that S-M-E switch too.

There are two things you need to check. Get some contact cleaner and clean the shift lever switch and also the little auto/manual* mode switch. This sounds like an electrical problem.
