Certainly having the transaxle codes should help narrow down this issue. A standard, consumer-grade scan tool won't access non-powertrain codes, so you'll likely need to use a professional scan tool to get this information. In otherwords, getting the transaxle codes probably won't be free.

It sounds like you're transmission is in 2nd gear, which would indicate limp-home mode. Does the shift lever allow you to shift to "1" or is "2" the lowest you can select? It's been awhile since I had my '98 SHO and it was console shift, so I'm not sure if that would allow me to select "1" or not.

Transmission Range Sensors have been known to cause some pretty odd electrical issues and for awhile it seemed like everyone was fixing their Taurii issues by replacing their TRS's.
