Flashing MIL after 24x conversion

[joecar]

Also gm.tstate00 pid says 'no' for in p/n while monitoring. is the pcm seeing this and not letting CASE work?

Maybe...

you might need to swap the trans segment from a manual trans file with same OS id (there may or may not be one available).

My summary page states that trans type is 'manual'. Why would it looking at auto trans range selection?

Post a screenshot of this...

if it's derived from the VIN then it is meaningless in regards to what the calibration actually contains.

I posted my tune on the first page. Post two I think. When I open tune it states 5.3L as engine and Manual as Transmissionn type.

This is my problem. I have 32 and 34 grounded and PCM still thinks I am in Drive. P/N status is 'NO'

What do I do?

Can you move this thread to the appropriate category so I can get some more views? I didn't realize I posted it in the Scanning forum.

Do a segment swap from an auto trans vehicle. Then ground C1-32 and C1-34 during the relearn procedure and see if that works. If it does then you can flash your manual trans segment back in.

Moved thread to Conversions.

Worked great, Lextech. I am now able to do crank relearns.

Unfortunately I am still getting a large amount of misfiring on cylinder 4 and 7 after this conversion. New ckp, swapped coils with 4 and 8, new wires... ran great before the swap.

You are using a Gen3 calibration on a traditional smallblock Chevy engine. They don't have the same firing order. Check the wiring portion for the firing order of the coils and injectors.
