Go to the dealer (without the truck, or just don't let them touch it) and request from the service writer a "VIP Report" print out. You will only need the last 8 digits of your vin number. Since you are the owner, it shouldn't be a problem to get this.
That will show all the dealer-done work on the truck, including the recalls. It should also show any uncompleted recalls. Do NOT let the dealer connect their scanner to the truck EVEN FOR CODES because it may possibly automatically update the firmware in the various systems in there. This is what you do not want. You DO want the upgraded parts from the F37... IF it hasn't been done.
If I am out of warranty do they still need to do the F37 parts if it has not been done?
Sorry for asking a dump question. I have not been buying nice vehicles that long. with the Subaru I had last I bought it a few years old and checked it for recalls. all there was on that was a clip they added to the throttle cable so it would not get stuck when using the cruise. when I inquired at the dealer for that they told me it had been done. that car was out of the bumper to bumper then too.
There is a BIG difference between a recall and a Technical Service Bulletin (TSB) that should be clarified first:
A recall is mandated by the government to fix some safety flaw in the vehicle. It will be done free, to any vehicle that has the problem design. Warranty or age does not matter.
A TSB however, is something that the manufacturer has decided to 'upgrade' because of a design failure that may not cause any safety concerns, BUT may affect the life of a given component or system. These are also sometimes called 'customer satisfaction repairs' because they are done based on an individual vehicle's presentation of the symptom when not every vehicle of the same model exhibits the same problem.
The F37 is a TSB. It was discovered that Chrysler selected a sub-standard torque converter for the original installation in our CRDs, and they decided to repair them with better components. At the same time, they decided to reprogram the engine computer and reduce the available power output of the engine electronically. This can be un-done with a computer tune from Green Diesel Engineering (A much better tune than Chrysler's) or from InMotion. The second change is the transmission control computer was also reprogrammed to change the shift points of the torque converter, again to protect the STILL sub-standard part they were installing at that time.
The F37 TSB's torque converter part has now been upgraded a second time, and they will be installing the European torque converter part. Reprogramming of the computer to reduce the power output is still taking place however.
So in this instance, they do not HAVE to do the F37, but they will bug you about it every time your truck visits a dealer. There is a decent possibility that you can still get the parts and install done for FREE, which (if your truck is still running the original parts) you should want to do. But you have to then get the programming done too. The engine computer programming can be un-fixed for you, the transmission programming cannot. This isn't a HUGE thing for most people however.
Where the biggest difference in the programming is, is the power mapping for the transmission computer, for the individuals who desire to take their CRD far beyond the Factory power levels. I am one of these people. I have already upgraded my torque converter and the computer programming, but the transmission computer is still the same one that I had after the f37 was done to my CRD before I bought it. Unless you plan to squeeze every last HP out of your engine, the difference probably wouldn't even be noticed by swapping Transmission computers with me. Then you would be safe to get the upgraded parts from the dealer, and the lifespan of your CRD would be greatly increased. If you decided to get an engine tune in the future, Green Diesel would be your best bet for their ECO tune, which adds an average of 6mpg to the CRD.
