    Welp, I blow'd er up. Time for a new build!

    WTB DB2 Cores

    2 of the 5088 and a 4911 which I'll probably keep . 4410 , 4126 and 2 of the 4544 pumps for the 6.2 . Another 4544 with the top off . I have no idea what these are worth , the core prices on the web are nuts ! If you want the better condition pump , one of the 5088 pumps was off a G van with...

    Throttle position sensor part # and source?

    Probably be next week until I can get to it . I'm at the top of the Beltway where 95 meets . The gauge blocks might be for setting a 700R4 . Anyway they were .660 if I remember correctly . Have you tried B&B off Central Ave for parts ? Crazy Rays had some trucks but they don't let them sit very...

    I've got one of those EPROMs , BLUE means nothing . It's the letter code on the other side that's important . Yes , you basically have a standalone ECM .

    4l80e/6.5 NA limp mode??

    Looking in the shop manual , no Trans light . If you had a P code engine , they call it a Service Throttle Soon . In the speedo , you have a red Brake light . To the right would be Air Bags light if you had them .
