Transmission Fluid

Capacity 10q30 9L800. Do NOT use MerconLV \ SP \ ULV or TypeCVT \ F \ FNR5 Fluids; they'll damage Ford 5r55e Transmissions. Only use Fluid that is Compatible\Compliant with the MerconV specs such as:

MerconV.BaseOilATF

MerconV.BlendedATF Options

Transmission Maintenance

For 1995~2002 built Ford 5r55e Transmissions, like this one built late in 2000, an apparent consensus amongst
experienced mechanics is that the maintenance tasks below be performed, so to preserve operation & longevity.
Photos & notes should be taken of each part before disassembly or removal, as required for proper reassembly.
Use a PermanentMarker & PlasticZipperBags to tag & store smaller parts; this will keep them organized & clean.

These items should be done AsSoonAsPossible\ASAP:

~ With DripPan & ShopRags ready for 4~7qts of ATF (2WD ShallowPan holds less, 4WD DeepPan holds more),
unclip & move the HeatShield off the right Pan Flange, then loosen the FactoryOriginal Pan by slowly loosening
the 18 FlangeBolts & using a clean ThinBladeScrapper as needed to carefully crack the Flange & Gasket open.
Patiently allow the ATF to drain & drip into the DripPan; don't be in a hurry to take an ATF shower; roughly 2qts
can be prepumped out of the DipStickTube to minimize this mess. Loosen & remove FlangeBolts in slow stages,
allowing time for the ATF to drain & drip. As the last FlangeBolt is removed, carefully lower the Pan & empty the
remaining Fluid to the DripPan. Measure & note the total pumped + drained Fluid throughout this procedure as
an estimate of refill quarts needed later. The original Pan was factory fitted with no Drain; it's recommended the
original be swapped to an aftermarket Pan with a DrainBung or drill & weld a new DrainBung in the original Pan,
then add a DrainMagneticBolt or DrainBrassBallValve; adding a Drain makes routine ATF changes much easier.
Slowly loosen the 1 Bolt holding the Filter to the bottom of the ValveBody; if needed carefully pry the Filter loose
with its Bolt partially engaged; allow ATF to drain & drip. When drip is stopped, unbolt & remove the Filter & its 2
ORings; again allow Fluid to drain from the ValveBody. Inspect & clean Pan+Magnet; remove old gasket & clean
both Flanges; disect & inspect the Filter; make note of any fines or debris. Here are search links for these parts.
