i suggest you start looking for a new trans.
130k miles with no fluid change, not good.
i did the same thing with a 95 lego. i bought it at 75k, reverse went out at 166k.
i drove it for a couple of months with no reverse while looking for a donor.
change the fluid again. read the trans codes and see what they say.
it may be something simple like a temp sensor, but i doubt it.
do you have a flashing AT Temp light (or Power light) at start up?
do you have a Check Engine Light?
