Oil pan and filter related items

Part Number	From	To	Comments	Suggested Retail
F6AZ-7A194-A	1996	2005	Factory installed deep sump pan. If installing this pan on a 1992-1995 vehicle, you will also need a new deep sump style filter.	$23.92
F8UZ-7A194-AA			Factory installed deep sump pan with drain plug. Used on 1998-2004 E-250 econoline vans delivered to the U-Haul corporation	$73.27
F2VY-7A191-A	1992	2005	Molded rubber gasket that seals the pan to the transmission case. If your vehicle is relatively new, you can likely re-use your current gasket.	$14.63
F6AZ-7A098-A FT-105	1996	2005	Factory installed transmission filter on 1996-2005 crown vics This is also the filter that you need to install a 1996+ transmission pan on a 1992-1995 crownvic. Note this filter is not compatible with the AOD transmission installed in some early 1992 crown victorias.	$26.91
N605785-S1036	1992	2005	Bolts that hold the transmission fluid pan to the case. There are 14 of these. To lower the chances of breaking the bolts or stripping out the case, make sure to apply some penetrant oil to them prior to removal  M8x1.25x16	$0.69
E9TZ-7L027-A	1992	2005	Pan magnet. This magnet attaches to the pan and attracts metallic debris in fluid circulation. This magnet is very strong and would be well suited to hold heavy papers to a refrigerator or dishwasher door. This magnet is also used in numerous other ford transmissions including the E4OD, 4R100, AX4N, 5R55S, etc.	$4.22

Notes:

• To make the 1-2 shift feel firmer via an accumulator spring change, install a higher rate spring on the top and a lower rate spring on the bottom. For an extremely firm shift, the bottom spring can be removed entirely, but this will result in very hard shifts on light throttle application too.
• The molded rubber style pistons were introduced into production crown victorias part way into the 1997 model year. Many early 1997 vehicles still used the older style aluminum pistons with rubber o-rings that were prone to fluid leaks and case bore wear. If you are changing accumulator springs, order new pistons too. And if you have an early 1992-1996 vehicle, you should consider replacing the pistons with the later revision 1997+ bonded rubber design to prevent transmission damage in the future.
  
• If changing the filter, inspect the valvebody closely to insure that the old filter seal ring has been completely removed from the sump port. If the old seal is inadvertently left in place and a new filter installed, low apply pressure will result in damaged clutch friction material when the vehicle is driven.
• If you live in an area of the country where chloride salts are used during the winter to keep the roads clear of snow and ice, it would be a good idea to lubricate the pan bolts a couple days ahead of time with some penetrating oil. Snapping a bolt and having to drill it out and then helicoil the hole will greatly complicate a fluid change project.
• If you are servicing a 1992-1995 crown vic, you should consider upgrading to the deep sump fluid pan and filter. Part #'s F6AZ-7A194-A and F6AZ-7A098-A This will help prevent fluid starvation to the clutches during hard turns and other evasive maneuvers. Also, if you need a new pan for a 1992-1995 vehicle due to collision damage or corrosion, you will be forced to do this upgrade since the older style pans are no longer avaliable from ford as service parts.
• There is also an application chart for 1-2 accumulator springs listed in TSB 97-11-11
