Repairing or replacing a vehicle’s transmission is a major job, and you could be looking at a very large bill if you leave it all to the mechanic. However, if you’re capable of dealing with your 6.7 Cummins transmission on your own, then you could potentially save a large sum of money. +Read more
There’s also a middle ground. If your 68RFE transmission is failing or has failed, then finding an entirely new 68RFE transmission for sale and fitting it yourself could be the easiest route to getting your vehicle back on the road. There’s also the option of buying a 68RFE transmission rebuild kit and refurbishing the vehicle’s transmission on your own. This is the cheapest, yet most labor-intensive option. Although it involves the most work, the rebuild kit should make things quite simple as it will contain all of the parts you need to refurbish a 68RFE transmission.
Sometimes, a specific transmission component is past its best and just replacing that part will solve your vehicle’s issues. For example, if your vehicle is struggling to shift gears at all, then there’s a good chance that your 6.7 Cummins torque converter is failing and needs to be replaced. You can simply replace the torque converter and get on with things, though if you’re going to the trouble of removing and opening up the transmission then it may make sense to do a full refurbishment anyway. Replacing parts that are likely to fail over time, even if they’re still in working order, could save you a further time-consuming and potentially expensive repair in the future.
You also have a golden opportunity to perform some 6.7 Cummins transmission upgrades if you’re working on the vehicle’s gearbox anyway. However, you don’t need to be working on a full transmission refurbishment for an upgrade to make sense. Fitting a new 68RFE transmission cooler is one of the simpler gearbox jobs you can do. So even if your transmission doesn’t need extensive work, it’s probably worth thinking about a 6.7 Cummins transmission cooler upgrade.
An upgraded transmission cooler will keep everything running colder. This in turn reduces wear on the transmission and brings down your gearbox’s failure risk significantly. Performing this kind of upgrade means you can likely avoid having to refurbish or replace your transmission for a significant amount of time.
