Changing tranny fluid

[Bob Lawrence]

Hi guys,
Want to get your feeling about changing the tranny fluid.
My bird has 130k on it and I don't find any records of the previous 3
owners changing the fluid.
Since we live in our bird fulltime and maybe take a trip once every
other month for a 3 dayer, no problem.
This Fri I'm going to get the oil changed (5k on engine rebuild) and
change the tranny fluid.
We will be traveling fulltime in 18 months and want to know if we
should change to synthetics.
I have notice the tranny temp gauge going up in stop and go traffic
and I have read the synthetics cut down on the heat factor.
Is it worth the expense ($8.00 a quart)and how long does it last
before needing rechanging?
Should I just stay with the conventional stuff in there now (changing
it out, of course).
What think you?
