To Flush or Not To Flush

Well I know this can be a heated debate. My libby had its ****** flushed at 120k miles it has 196 on it now. It is working and operating perfectly. My routine maintence side says to flush it. My main mechanic in the shop says dont touch the ****** if it is working fine. What do you guys think?

There are obviously two ways to go, flush or no.

You have been maintaining the Jeep, why not continue to do so?

The main mechanic answer probably stems from his worry that a flush will cause things to loosen up and clog ports, valves etc. And if it's working OK, don't futz with it.

Just drop the pan, change the filter(s), then fill the trans with fresh ATF+4.
Then you will be back in business and running great (woot)

When in doubt, flush it.

No flush. Change the fluid and filter.

Alright sounds like I will be picking up a couple filters and some ****** fluid. I readd the how to. Is it necessary to have "mopar" fluid? or can I just get ATF from Napa?

If you had it flushed for the 1st time at 120K and had no issues and now at 196K another flush is not going to hurt it.

Use only ATF+4 only.

Doesn't matter as long as it's ATF+4.
