2006 Dodge Charger RT with 392 engine swap
Using NAG1/A580 transmission & original wiring harness.
New:
-Transmission
-Valve body with conductor plate & sensors
-TCM
-Rear CV axles
-Rear ABS sensors
-?Shift electronic module?
-Inspected wire bundle from pcm to tcm
(My last thought is possible bad pcm?)
Transmission shift points are very late/delayed from 1-2 and 2-3 and the transmission will not shift past 3rd gear on its own. If allowed to shift itself to third, it gets stuck in third until car is restarted. All 5 gears can be utilized ?auto stick? without issues unless put back into auto mode. For example, if driving in manual 5th and I put the transmission into auto mode, it?ll jump down into third no matter the speed.
Using HP tuners, I have tried resetting the transmission adaptives, preforming an ?EGS5X init? procedure, verifying and entering proper tire diameter, gear ratio, etc into the computer
When the transmission gets stuck in third, I get a P0733 ?gear 3 incorrect ratio? code. That is it for codes.
Also- the transmission will work and shift through all gears if I go into hp tuners and disable ?traction control? which disables the abs and displays both abs and brake light on the dash. However, I have no abs codes.
I have also tried reuploading the tune which was downloaded before the car had any issues. Any help would be greatly appreciated - thank you!
