2005 Volvo VNL with 2nd gen Eaton Fuller 3 pedal autoshift

2005 Volvo VNL with D12 engine and 3 pedal Eaton Fuller 2nd gen Tranny is acting up(hesitating to go in some of the gears sometimes). I called Eaton and they told me to test is in manual mode and I did it but still hesitating to get to 5th or 10th gear( eventually will go in but it takes 3,4 seconds) . Eaton service told me that is most likely Tranny ECM. There is NO codes in Transmission diagnostic and there is NO codes on Tranny shifter(when I try to Retrieve it either ). There are also no codes in Engine diagnostic, voltage is solid 13.7 system air pressure is good at all times. I cleaned battery conections(batteries are fairly new and tested), all connections between Tranny and batteries cleaned and ziptied.
The only codes that I have are in Vehicle ECU and they are INACTIVE :
*SAE J1708/J1587 data link Data erratic( MID 144 SID 250 FMI 2)
*Retarded control set switch Mechanical fault (MID 144 PSID 1 FMI 7).
First code I've had for awhile and even though I've changed all speed sensors somehow its still showing up.
Second code is new and I am wondering what it can be. Did a Google search and Volvo code search but nothing is showing up. Any help would be appreciated.
P.s. Truck was put on computer to retrieve codes and nothing is showing up

 

Anybody?
