You don't mention any CEL's.....your GP light may be voltage related or a bad connection/ground. Check the condition of the wiring harness, some early 96's suffered from deterioating wiring insulation. Might want to monitor voltage while driving using the CCU (key on, hold REST for 5 secs, use AUTO buttons to toggle to screen 24). After the GP relay clicks off (~2 mins after starting), voltage should be around 13V at idle and pushing 13.5V when accelarating.
The crossover flaps and EGR valve are typical causes of surging with your engine. Check vacuum lines and look for rotten rubber. After 16 years some of it will need replacing.
If you go the indy route you might want to pick someone different than the original owner used.....

This alll sounds like a transmission problem to me.
