no, you better have put all the older style switches in teh newere engine as your copmputer may not hoook up to the new switches/sensors.

the answer is still no lke th first answer because all of the elcectrical connections are different thatn the 98 trans. there may be other switches int eh newer trans that aren't in the old one or vice versa.
