Does your 95 have the f22 in it? What engine does the 98 have, the h22 possibly? Im not too familiar with manual/automatic conversions but if they're both 5 spds the two will swap fine. if you are upgrading from the f series to the h series, i believe you can keep the f series tranny, but i wouldnt recommed it. i doubt that it would last very long. The 95-98s are a little vauge to me, the intro of the 6 cly and f 23's. Do you have any more info on what engines your looking to swap?
