i have a 01 grand caravan. strated getting 740 code.Inotice no issues with tranny,its old and has 188k.Does anyone have any idea how long trans might last.Don't really want to put much money in it.I read in a few articles it might be good for a while since its not showing any issues or is it the cloud before the storm

This one shouldn't be too serious. Just a connector or a fluid problem.
