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.
