i just recently swapped a jdm b16a2 auto tranny onto my 93 civic hatch auto tranny also.

when i shift , park is park = normal,
when i go to reverse it reverses
it does the same thing for neutral,
d4 is neutral, and d3 runs,
so im guessing d3 is d4. and 2 is d3 and 1 is 2.
im guessing its a gear behind? any way ucan fix this?

i would think either improper linkage adjustment or maybe the jdm trans is different than the usdm trans. research the jdm transmission.
