The problem with your logic is with the introduction of the 2.8L in model year 2005 the design limit of the 545 transmission was met :roll: The previous engine was 2.5L :lol:

Re-read the statement I was responding to. Whether or not they got it right on this one is not the point, he was saying that they had no experience with diesel, which is patently false.

The auto had a 2.8 far earlier than 2005 but it had a lower output. 2005 models got the VNT turbo and more power/torque.

Thanks Reflex,

I agree the the D part of DCJ has done diesel, but I'm not sure that I would go so far to say that the C or J part have had that same experience. And with D buying CJ and the merge going over many rocks, I would not be willing to say that the diesel experience conveyed. The designers of the CRD did not seem to have insights into the torsion issuses with a 4 cylinder diesel of this capability and the reinforcements needed in a TC.

The timed nuetering to protect the failing torque converter (TC) betrays DCJs ignorance of diesel production vehicles by their use of a TC designed for petrol engines.

DC makes diesel products all over the world and has for years. They have lots of experience in this area, including in the Liberty which has had a CRD version outside the US almost since its inception.

Further evidence of the performance degrade is the changing of the EPA MPG numbers. This is evidence of the detune as with the change in the setup, they were required to update the EPA data.

Every manufacturer was required to update their data on all models. This had nothing to do with changes to the models, this had to do with the fact that the EPA changed their methodology. Go to fueleconomy.gov and you can find 06 and earlier estimages as well as most of the older vehicles with the new 07 and later style estimates.
