Step by Step. How to Installed a Dodge Ram 68rfe Double Deep Transmission Pan
2. Place a large diameter shallow drain pan beneath the factory transmission
pan. Also, keep some rags handy as this can get messy.
3. Remove the bolts holding the front and sides of the factory pan to the
transmission.
4. Loosen the bolts holding the rear of the factory pan to the transmission.
5. Slowly separate the front of the factory pan away from the transmission
allowing the fluid to drain into the drain pan.
6. Hold up the factory pan and remove the remaining bolts holding the pan to
the transmission.
7. While holding the pan level, lower the pan away from the transmission.
8. Pour the remaining fluid in the factory pan into the drain pan.
9. If changing the transmission filters, follow steps 10-16. If not, skip to step 17.
10. Remove the screw holding the primary oil filter to the valve body.
11. Inspect the oil filter seal from the bottom of the oil pump. If the seal is
installed correctly and is in good condition, it can be reused.
12. If replacing the cooler return filter, remove it drain the excess transmission
fluid into the drain pan.
13. If necessary, install a new primary oil filter seal in the oil pump inlet bore.
Seat the seal in the bore.
14. Place the replacement filter in position on the valve body and into the oil
pump.
15. Reinstall the screw to hold the primary oil filter to the valve body. Torque
this screw to 4.5 N-m (40 in-lbs).
16. Replace the cooler return filter and be sure to not over-torque the filter. It
uses plastic threads which will crack if over-torqued. Torque this filter to 7-
ft-lbs or ¾ turn after the gasket contacts the base

ATS strongly suggests replacing the plastic coupler with our billet
aluminum filter coupler (ATS p/n 301-021-2326). These allow the
installer to torque the filter in place like an oil filter to ensure a
positive seal. The factory plastic couplers are very prone to cracking
if over-torqued. If under-torqued, engine vibrations will eventually
cause the filter to fall off. In either situation, transmission oil
pressure is lost and will severely damage the transmission.
17. Apply some new transmission fluid to the o-rings on the filter extension
and slide the o-ring side over the pickup on the filter, rotating slightly to
reduce the possibility of pinching/cutting the o-rings.
If an o-ring is damaged during installation (a piece of the o-ring
shaved off by the edge of the filter), remove the damaged o-ring and
replace it with one of the spare o-rings included in the kit and
reinstall the filter extension.
18. Using a gasket scraper, clean any gasket or sealing material from the
surface of the transmission case.
19. Place the new ATS deep transmission pan into position with the new
gasket and torque the new hardware to 12 N-m (105 in-lbs).
20. Located on the side of the transmission pan is a hole tapped for 1/8NPT.
If installing a transmission temperature gauge, this hole can be used for
the temperature sending unit. If not, install the 1/8 NPT pipe plug included
with the kit.
21. The 68RFE transmission with a deep pan requires at least
22 quarts of
ATF to fill when completely dry. Transmissions equipped with the factory
pan hold about 17 quarts of ATF. When dropping the factory pan to drain
the transmission, only about 6-8 quarts are removed (this can be more
depending on how long the transmission is left to drain). This leaves
between 9 and 11 quarts still trapped inside the transmission and torque
converter. From here, there are two options:
23. Check for leaks and if none are visible, installation is complete.
Left Stock Vs. Aftermarket
A. If the transmission fluid appears clean and in good condition, it is
ok to add new fluid without completely draining and flushing the
remaining fluid in the transmission.
If this is the case, add 8 quarts of fluid thru the fill tube.
Start the engine and allow to idle in PARK and immediately add an additional 4 quarts. Allow the truck to idle for about 20 minutes.
Then, with your foot on the brake, run through PARK, REVERSE, NEUTRAL, DRIVE and back to PARK allowing each gear to engage but DO NOT move the truck. Continue this for several cycles. With the engine running and the truck in PARK, check the fluid level and add as necessary until it is near the full mark.

B. If the truck is due for a full transmission service, it is possible to
completely drain and flush the transmission in your driveway or
garage, however, we strongly suggest having a qualified technician
perform this task. Serious damage can occur if you run the pump
dry.
68RFE pumps are VERY sensitive to losses in lubrication because the steel pump gears ride inside an aluminum housing and require a layer of oil between the moving parts. If this oil layer is lost, the steel gears will chew into the aluminum housing ruining the pump.

C. In either case, fill the transmission with Mopar ATF+4 or a fluid
that meets ATF+4 spec. These can be found at nearly any parts
store. We recommend avoiding ATF's that say "compatible with"
or "replaces" ATF+4. Any brand is fine as long as it meets the
spec.
When draining the fluid, it is a good idea to keep an eye on how much drained out. If more than 8 quarts came out, for instance, if 12 quarts came out you'll need to add back that 12 plus an additional 5 (i.e. a total of 17 quarts) to make up for the increased volume supplied by the deep pan.
