I have replaced my 92 AX15 with an 96 AW4 tranny and NP242 TC. Everything works great except one quirk. When on the hiway and cruise on, approach a hill and the tranny kicks down a gear. So far so good. When it kicks down the cruise control shuts off. This should not happen. I find this odd since the PCM and the TCU are seperate. I suspect it may have somethingto do with a manual tranny set up the RPM does not change much when the cruise is on. Any thoughts? How can I cure this?
