47 re no first or od

[Jr90]

98 12 valve 47re, pcm has been rebuilt, new solenoids and wiring harness in the transmission. I left the batteries unhooked overnite to clear codes after solenoid install and Codes p0753 1765 are still showing now. Still starts out in first and wont shift into od. This thing is driving me crazy. Trans worked fine for a little while after pcm rebuild. Should I send the pcm back did I get bad solenoids? Or does it sound like something else entirely? Any ground locations to check?

Have you got yourself an ATSG manual for your 47re ? Has some good diagnostics in it. If not I could possibly snapshot pages and send them over.

No I do not have one, I did get it working though, cleaned ground connections to the body and cleaned the transmission connector. Hopefully it keeps it up
