Tranny shift points
 

I am a new member. I just purchased the Phoenix chip and have been running it for about 3 weeks in my 02 f350 (7.3). One thing I realized is the box code on the chip is ADH4 and after pulling out the PCM box, it is VDH4, my fault. Should I be concerned? Everything works great. I previously installed a Factory Tech Valve Body before the chip. Now the truck shifts incredibly fast even at very low RPMs, which causes the engine to lug down between shifts (not enough RPMs). It seems the engine and tranny are not quite in tune with each other, if that makes any sense. I guess I would prefer the shift points relative to the engines RPMs to be a longer duration of time and higher revs. I hope I explained that correctly. I have no problems sending in the chip for an adjustment, if it can be done. Thanks in advance for any info and guidence.

No issue with the box code. ADH4 doesn't exist and knowing that looking in a mirror can skew your view of the writing, we deduced that it was VDH4. Easy enough.

We use a strategy of VDH2 that is a hybrid of VDH2 and PMT1 for the torque converter clutch apply strategy since it appeals to more people. I suspect that you are concerned with the mid-to heavy accelerator pedal torque converter clutch lockup points. If this is the case, then we are sorry for any inconvenience. How does the truck shift otherwise; Is the shift feel ok? Too harsh or soft?

Please let us know what we can do to your shifting. We want to get it right for you so that you have a pleasurable experience.

Oh, and please let me know if it has the concern in every position (including stock) or just the 80T and 80DD tunes.
