ATF+4 in older transmissions

I need to change the fluid on my 1998 Dodge Stratus. When I went to
Walmart to buy the fluid, they only had Mopar ATF+4.

If I remember correctly, the TSB said that ATF+4 could be used as a
replacement to ATF+3, except for 1999 and before mini-vans.

I checked on Allpar.com, and there was mention about ATF+4 possibly
not being compatible with all earlier seals, which may cause them to
leak.

I will probably go ahead and do it, but just wanted to see if there
are any opinions on this.

Thanks,

KM
