My truck(1995 Chevy 1500, was hitting hard going into 2 gear(automatic) Ammco said it was ECC under dash, replaced it, now the truck does not even turn over. Does it need to be re-learned?

SOURCE: CHEVY 1500 TRUCK HEADLIGHTS TURN OFF WHEN YOU TURN ON SWITCH

If you have replaced the switch, and it is still doing it it sounds like you definately have a short somewhere in your wiring. On the other hand if the dimmer is in the turn signal arm ( forward bright back dim ) the problem could also be there in the dimmer switch, such as a short being caused by that dimmer switch being faulty.Auto Zone and Discount Auto Parts both test a lot of your electrical problems for free, and/or may have some knowledge to more accurately pin point the problem. Not sure about Pep Boys or some of the other discount auto part chains.

If you have no reverse then yes it needs to be rebuilt. as far as the whining it could be in one of the differentials. or in trans? just depends on where you hear it

You can remove the interlock off the gear shift or maybe spray some crc on it otherwise probably a loose wire or switch
