The trans does not shift in Drive and does require manual input to shift. The 1-2 shift feels firm as it should but the 2-3 shift is super slow... It probably takes 1/2 a second to shift under hard acceleration with the shift being kinda soft. Before I invest much time and effort into this trans, can anyone give me a rough idea on what might be causing this issue? Thank you

An air test is in order. The INTERNET, the MISinformation superhighway
