Tranny issues

Hi I have a 97 Bravada with 118k on it and im having some problems with the tranny. my main problem is that first gear shifts pretty rough. right before it shifts it's like theres a dead spot right around 2500. seems like it's almost just disengaging and then engaging slowly. just had the tranny flushed and transfer case fluid changed. The tranny feels loose in general compared to my old 93. i understand that the tranny shifting is controlled by a computer, could this have anything to do with it?

anyone?

You might try having the trans fluid AND FILTER changed if the "flush" hasn't damaged anything.
You should have a Check Engine light on with the Transmission Component Slipping DTC...P1870 I think.
