Hola Transsmission was rebuilt by another shop, vehicle came in with 123 and reverse only, neutralizing in 4th and above, i have heard of swapped connectors causing this, but they are ok, I cannot find any problems inside trans or with valve body. Has anyone seen something like this before? Good day everyone.
