Transmission Slip

Hello Allison Man
I have a 1994 Gulf Stream Scenic Cruiser with an Allison 6 speed transmission. The last two times I started the coach and began accelerating there was a momentary slip as the transmission shifted from 3rd to 4th gear. After that, as the transmission warmed up the shifting was normal. What are your thoughts as to the cause and proper tests/fixes to pursue?
Thanks,
Jack
