I have a 91' 240SX with a auto trans. I just put another tranny in it, and this one is doing the same as the old one. The first trans had 1st and reverse and wouldnt shift, SO I bought another trans and put it in and now the same thing. Someone told me that it was the speed sensor, so I got a new sensor($100...whew). Still nothing happened. I have 1st and reverse, But it will not shift, it acts like it wants to shift but it stays in 1st. When I bought the car the guy had already put the first trans in it, and he had some wires wired up into some other wires that go into a clip beside the fuse box under the hood. I have NO idea, if these wires are correct or if it is another issue. But I know it isnt very often that 2 trans are doing the same thing. Here is a pic of the wires..... any suggestions would be helpful, thanx.....
