Cummins/68RFE Reliability - how many miles?

3773 Views 51 Replies 17 Participants Last post by  jwolfe11
Thinking of buying a 2019 2500 CCSB 4x4 with the 6.7 Cummins 68RFE and 82k miles. I keep hearing the trans is the weak link on these trucks - is that true? How many miles are folks getting before having issues?

Are there any other common issues on the newer 6.7 Cummins? I haven't had a Cummins since my dad's 1994 24-valve model from way back in the day.

Thanks in advance!

I’d be more concerned about the CP4 recall work being done instead of the transmission. You can get tuning for the trans, and do some simple valve body upgrades and it’s a decent transmission. Or just keep your foot out of it 😂
