4l60e Transmission Fluid
4l60e Transmission Fluid Type & Capacity FAQ's
1. What Type of Transmission Fluid Does The 4l60e Use?
The recommeded transmission fluid for the GM 4l60e is Dexron 3 / Dexron 6 / Dex Merc.
Since its release in 1993, Dexron 3 (Dex III) was the recommended transmission fluid for the 4l60e. Overtime however, Dex III was phased out and GM released Dex VI in 2005. While Dex 6 is designed for newer vehicles and transmissions, it is backwards compatable with Dexron III transmission fluid.
NOTE: Dexron III cannot be used with transmissions that require Dexron VI.
Eventually, Dexron 3 was combined with Mercon and became Dex/Merc, which is the modern recommeded transmission fluid for 4l60e transmissions.
2. What Is The 4L60E's Fluid Capacity Dry, With Torque Converter, With Deep Pan?
The fluid capacity of the 4L60e is 12 quarts of transmission fluid (dry). This amount is based on a stock, “shallow” transmission pan with a 12″ torque converter. With a deep pan, the capacity of additional fluid can vary from an extra quart or more.
3. Should I Flush My 4l60e?
Flushing a transmission, even the 4L60e is a sensitive subject. Best practice is to do a fluid flush on your 4l60e as long as that has been routine maintenance. If not, then a simple fluid and filter change would suffice.
