I replaced the transmission on my 99 bravada and every thing went well. But when I drive it the vehicle tends to pull back the rpm's move up and down slightly and when I put it in reverse I have to push hard on the gas to move it. Is there a adjustment I missed or could it be something else.

I would nt think its an adjustment issue as no adjustment is needed
only adjustment I could come up with is for neutral safety switch
if tranny control module has no codes and no pending codes
it would be very difficult to help with out a scan tool connected to it and road test to verify the condition
RPM and tranny data
When pushing hard to go back do the RPM go high and truck having hard time backing up
and if so I would also suspect internal tranny issue

was it a used tranny or rebuilt

What did you mean by (when I put it in reverse I have to push hard on the gas to move it)
if using an OBDII reader you have no access to TCM data and codes
I would remove connectors on tranny and recheck
