4l30e transmission problems

hi, everyone. I have a 1994 rodeo thats is slow going in to reverse
all the time (no difference if hot or cold) but does not slip at all.Shifts
into forward gears with no hesitation. The only trouble im having with
forward gears act like it takes forever shift if it's really cold.But after
warms up it will shift fine other than taking a few seconds for reverse
to engage. (92,000 miles no warnig lights)

any info would be helpful. thanks in advance.

Have you had regular tranny maintenance done?

I really have no idea. I just traded for it a couple of weeks ago. Although fluid looks pretty clean.
