68RFE Updated Mopar OEM Solenoid Pack (All Model Years)
The 68RFE Solenoid Pack is the hydraulic, electronic and mechanical hub of the transmission responsible for opening and closing critical oil circuits at strategic TCM-commanded times to catalyze and facilitate desired clutch applications and combinations.
In simpler terms, it serves the role of controlling what functions of the transmission (such as clutch packs) turn on, and when and is a critical part of the 68RFE valve body. For further details on the failures there within, read our technical publication on 68RFE valve body failures and solutions here:

Naturally, this design however leaves the product open to many failures. The OEM 68RFE Solenoid Pack is generally reliable, but fails moreso due to aggressive valve body failures that introduce dirty oil to this unit and cause flexion to the internal pressure manifold of the pack itself, negatively impacting reliability.
Though this is the case, nothing is more reliable than an OEM 68RFE Mopar Solenoid Pack! There are various options on the market, often cheaper. This is a true, OEM solenoid pack, delivered in the original Mopar box, and is tested before embark. These should be replaced with ALL rebuilds and valve body swaps.
Model Year Guide:
Blue - 2019+
White - 2007.5 to 2018 (Natively 2007.5 to 2010, but will forward-fit any 2011 to 2018)
Grey - 2011 to 2018 (2011 to 2018 trucks can choose white or grey)
Footnote: There is a common misconception that grey solenoid packs are inherently less reliable than white solenoid packs. To the best of all research we have performed, there is no available evidence to suggest this in any capacity. In fact, the only reason for Mopar updating them with the white solenoid pack, is because they are a direct fit and there is no need for 2 part numbers that serve a common purpose.
This part replaces part numbers 68353383AB (Grey) and 68353383AA (White).
