#440, "RE: B&M TrickShift Fluid" In response to In response to 3
The A604 is very very picky on its fluids. Use only ATF +4 ( or ATF +3 if you can find it. ) Any other fluid will damage the tranny. The truth about the fluid from chrysler is that you can use ATF +4 on any vehicle that used or is using ATF + , ATF +2, or ATF +3. However if you have a vehicle that uses ATF +4 you dont want to add ATF +3. But as said above dont use anything other than that listed above or youll be rebuilding the tranny much sooner than youd like.
