New member here, thanks for the add. My brothers ranger with 2.3 auto has the od light flashing and I think it kicks out of lockup. I hooked up the autel and this is what I get. He did have a transmission shop repair it which is when this all started. Seems peculiar that everything is showing up at once like this. Anyone ever seen this issue.

 

Welcome to the forum

Need the YEAR of the Ranger?

I assume 2002 - 2011 2.3l DOHC not the 1995 - 1997 2.3l SOHC

Is the speedometer working?

Codes 1127 and 1288 can mean you checked codes when engine was cold, it need to be warmed up above 150degF or these will show up, so run it for 5minutes or so then re-test

If speedometer is not working then get under the vehicle on drivers side and look at rear of transmission for the 2 wire OSS sensor, unplug it and plug it back in, this is the "speed" sensor also calibrates "gear ratios"

Then look above the shifter for the 2 wire ISS sensor this also calibrates "gear ratios" unplug it and plug it back in

Unplugging connectors and plugging back in "cleans" them to make better contact, also to make sure they were plug in correctly

Also says there are 8 codes, I only see 7, whats the 8th code?

And what was the "repair", the trans shop did?
