Ugh, service manual note for a 2013:
TRANSMISSION FILL
To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:
Remove dipstick and insert clean funnel in transmission fill tube.
Add following initial quantity of Mopar® ASRC ATF to transmission:
If only fluid and filter were changed, add 6.8L (7.2 quarts) of ASRC to transmission.
If transmission was completely overhauled and the torque converter was replaced or drained, add 13L (13.75 quarts) of Mopar® ASRC ATF to transmission.
Check the transmission fluid and adjust as required.
I seem to recall reading this elsewhere before I bought a manual as well.
Thanks!
"I" will do a complete change and new filter every 30K.
