The 6L80E Transmission automatic transmission makes use of 4 underdrive gears as well as two overdrive gears. As a result, it doesn�t have the usual direct 1:1 ratio like the 4L60E and 4L80E transmissions. Here is the gear ratio of the 6L80E Transmission automatic transmission:
First gear 4.027
Second gear 2.364
Third gear 1.532
Fourth gear 1.152
Fifth gear 0.852
Sixth gear 0.0667
Reverse 3.064
6L80E Transmission Identification
You can identify the 6L80E Transmission in two unique ways. However, your identification method depends primarily on whether the transmission is still mounted in the vehicle or has been dismounted. If the 6L80E transmission is still mounted in the vehicle, you can only identify it using its RPO tag in the vehicle�s glove compartment. This is why knowing the RPO code for the transmission you want to identify is nothing short of golden. For instance, here�s a list of GM transmission RPO codes you should know, arranged in no particular order:
6L80E MYC
