what do you have to do to connect 1995 wire harness to the 2000 trans mission. is there an adapter?

tans is in car but can't connect because of different sensors...what now take it back out???

Do you have one installed now but can't connect or are you "just asking" before you do the swap?
In '96 most manufacturers made major changes to the wiring b/c ODBII Federal requirements. There is almost zero compatability between wiring harnesses -95 and 96- If you are doing a swap you may want to stick to parts from '95 back for your '95.
