'98 Plymouth Voyager - ATF +3 or +4?

[zebra14]

Greetings - we have a '98 Plymouth Voyager with the Mitsubishi 3.0 V6. I had the automatic transmission rebuilt about 15K miles ago and figure it's time to exchange some old fluid for new. I have been trying to figure out which AT fluid I should use. As I have a 1998, it appears to be a pivotal year. Some websites recommend that if it's older than 1998, one should use ATF +3. Yet I have also read that ATF +4 is the stuff to use as it supercedes ATF +3.

Any recommendations as to which fluid I should use? The manual says ATF +3 7176.

I have read to use what the manual recommends, but I have also read that ATF +4 is better replacement.

Can any Chrysler owners set me straight?

I don't think +3 is being made anymore. Anthing on the shelf is more than likely old stock. I would use the walmart +4 at $2.97 a quart. It's a better fluid and backward compatible.

+4 replaces +3, and it is an improvement.

+4 is the proper fluid for that tranny. Choose the cheapest +4 brand(usually supertech) as every one of them is exactly the same. Same basestocks, additives, everything.

I posted the same thread here first:

and some are saying I should stay with ATF+3, yet I'd like to go to ATF+4 as it sounds better and I should have a problem with it. (famous last words)

Upgrade to the ATF+4.
