45rfe Valve Body

Cause: May be the sump filter is cracked on the seam or the neck seal is loose or missing. allot of filters are splitting down the side of the seams. may or may not have trouble codes P0868, main pressure. P0868, loss of prime, P0731 ratio in 1st. P0736 ratio in rev. and other codes. may be only cold first time engagement issues, depends on severity of crack and seal issues etc. If filter was just changed check the seal and possibly new filter is cracked as well. (check your cooler spin on filter if you have the split sump filter if pt # 4799662AB this can be why your sump filter is split, During converter drain back you can get air in the system and when engine is restarted this filter has check valve issue that allows air to blow open the sump filter, replace spin on filter) Another possibility is the cooler filter (screw on cartridge type in pan) has the holes restricted by the seal. use Chrysler filter 04799662AC is best bet. check holes are not restricted if using aftermarket filters.
