My 5.7 Hemi with the 545RFE took 8 quarts of ATF+4 to bring it to the full mark after changing both filters. I started with 5 or 6 quarts and then slowly added, after running it a bit, until it read full when hot. There are two filters. The return filter is a small screw on (like an engine filter) and the main filter goes over the pump pickup tube. Be sure to remove the old "neck seal. In order to avoid problems (sucking air), this caution in the shop manual must be adhered to:
"CAUTION: The primary oil filter seal MUST be fullyto the transmission will result."
installed flush against the oil pump body. DO NOT
install the seal onto the filter neck and attempt to
install the filter and seal as an assembly. Damage
