So I got done installing my aw4 in my 1997 jeep xj. I was told the new transmission was out of a newer jeep xj. The only thing that looked different was the output speed sensor. So I cut and spliced the wires going to that. My jeep starts fine goes through the gears fine when parked. But when I get going it has power to 1st and when it shifts to 2nd, it bogs down. Could the wires be installed wrong on the speed sensor or? Thanks
