2001 sierra allison problem scanning

[chucker81]

I have an 01 sierra crew with 8.1, and the transmission can't be read from the scan tool, live data and what not.... Any Ideas? Also it vibrates above 50 and the fluid is brunt.

your POS scanner cant read it ,

 

go to a place that can scan it ,simple

 

vibration could be anything,,take it in

 

these trannies are awesome ,dont worry to much ok?

Its a geneis OTC, so not a pos. Also my Bully dog programer wont read tranny temp says 32 degrees all the time
