well yesterday im driving with my friend in his 98 gtp with 130,000 and all of the sudden the rpms started bumpin up and down rapidly while cruising at highway speeds with light load under heavy load it would be fine. then at stop lights it would whine really bad and shudder the car and move slowly but if you punched it it would be fine, we got it back to the house doing 100+ keeping the foot on the pedal the whole way the tranny seemed good when driving like this, but get it back to a stop it would act up. we did for $h!t$ and giggles a flush and service to see if it would clear it up, it did but now it just bumps really hard and feels like it slips and catches. is the tranny gone? or TC? valve body? whats the best fix? he just bought the car like 3 weeks ago. can we get around doing the tranny? im not a tranny expert by any means so opinions/ideas would be great
