ATSG CONFIRMED FIX - AUGUST 2024
2015 Dodge R2500 68RFE
Complaint: After Rebuild, truck had a good reverse until after a couple road tests, then it lost reverse completely.
Cause: Defective aftermarket input drum cut the inner o-ring seal between the forward clutches and the reverse clutches.
Correction: Replace the input drum with OEM.
Part numbers related to the repair: NA
Year Make and Model of the Vehicle: 2015 Dodge R2500
Mileage: NA
Shop Name: Sampson Transmissions

Additional Notes: During rebuild the input drum had to be replaced.
