As most everyone is aware there are issues with the shift quality of the Nitro transmission. A TSB is available to correct various problems with the transmission. TSB 18-037-06 FLASH: Vehicle Surge, Grumble/Drone During Torque Convertor Lockup And/Or 1-2 Part Throttle Shift Quality.
However, members are still reporting torque converter shudder as well as a transmission bog. I performed the TSB on my Nitro shortly after it was released. My vehicle has 2000kms and there is a transmission shift issue. The transmission does have torque converter shudder at 70km under light to moderate throttle. Also the 3-4 shift is poor. During this shift is appears the torque converter is locking and unlocking as well it downshifts briefly to 3 after it has shifted to 4th and then back to 4th. This is easily seen on the tach.
I sent an electronic product report to Chrysler Engineering last week reporting the transmisson shift issues. I received a call today from one of their engineers. He stated that he wants the torque converter replaced. If that doesn't cure the problem he then wants the torque converter break-in enabled.
I have not ordered the new torque converter. Instead, I performed a transmission quicklearn and re-enabled torque converter break-in. This is an experiment of mine. I want to say that enabling T/C break-in can shorten the life of the component. This will be the second time this feature is enabled. It first was enabled from the factory which is normal.
On my drive home the transmision shifting was very normal. No shudder or hunting between the 3-4 shift. I need to give this about a week, maybe less, to verify the results. It may be inevitable that the converter be replaced, but I will post my results.
If anyone has questions about this, don't hesistate to ask. I'll answer the questions I can.
