fluids (maintenance)
#12
Dodge told me it only took 4 qt's when servicing the trans but they were wrong as it it took about 6.5 Qt's to refill. What I have noticed since then is that every post I've read about servicing the trans is that it took between 6 and 7qt's of tarns fluid to refill, more if you have an aftermarket extra capacity pan. The best Trans fluid is Amsoil IMHO.
As for fuel filters the best filters either #1 Baldwin PF7977 #2 Fleetguard Stratapore and last Dodge, thou I've heard that Donaldson is now making new fule filter to meet Cummins Specs. For oil the best oil filters are Donaldson ELF/Amsoil or Fleetguard Stratapore.
BTW don't fall for the Mopar ATF+4 is synthetic its not. Below is some info from Allpar website about ATF+4 trans fluid:
The use of Group III base oils is probably the leading cause for ATF+4 being a more expensive fluid than ATF+3 (which according to the paper uses a Group II base oil). The paper noted that one alternative was to use synthetic Group IV base stock, which are even more expensive than the ATF+4 solution,
Below is some info about oil groups:
Group I base oils can have a mix of different hydrocarbon chains, with relatively little uniformity; these oils are the least refined. They are usually not used for autos.
Group II are the most common base oils in “dino juice,” with good performance in most areas except cold temperature viscosity.
Group III are called synthetic, and have high molecular uniformity and stability. Group III oil bases are used in most synthetic oils.
Group IV are chemically engineered stocks, arguably with the highest performance and longevity.
