# Service bulletin T01

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10139999
- Published by NHTSA: 2018\-06\-11
- Manufacturer's number: T01
- Manufacturer's date: 2017\-03\-01
- NHTSA component: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\)

## NHTSA's summary

Customer Satisfaction Notification T01 Reprogram Powertrain Control Module The Powertrain Control Module \(PCM\) on about 15 of the above vehicles may have received PCM software containing calibration errors when recall S49 was performed. PCM software containing calibration errors may result in the radiator cooling fan producing excessive fan noise during operation. The PCM on involved vehicles must be reprogrammed with new software.

- [S1709000010](/bulletins/10229031.md), 2023-01-09, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). Customer complaints may include abnormal engine noise, rough idle, lack of power, misfire. Upon investigation, it may be found that there is excessive camshaft lobe wear/lifter wear \(roller failure\) on one or more cam lobes and that camshaft/lifter replacement is necessary.

- [0801515](/bulletins/10223623.md), 2022-10-17, Service bulletin: POWER TRAIN; POWER TRAIN:AUTOMATIC TRANSMISSION:GEAR POSITION INDICATION \(PRNDL\). Flash: Gear Shift Indicator System Enhancements This bulletin involves reprogramming the Power Control Module \(PCM\) with new software. A small number of customers may experience improper gear shift point indications displayed in the EVIC if the paddle shift mode is selected on the steering wheel.
- [W41](/bulletins/10221748.md), 2022-09-26, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). Customer Satisfaction Notification W41 Reprogram Powertrain Control Module
- [1801914REVA](/bulletins/10221078.md), 2022-09-26, Service bulletin: ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). Flash: Power Control Module Software Enhancements This bulletin involves reprogramming the Powertrain Control Module \(PCM\) with the latest available software. The customers may experience one or all of the following: \- Customer may experience a "detonation" type of noise while accelerating or at idle. \- Customers may experience Cruise Control lock out \(inoperative\) after several ?\+? cruise button inputs attempting to increase Cruise Set Speed. Turning the ignition off and back on will clear the condition. \- MIL light illuminates and DTC P2463\-00 ?Diesel Particulate Filter\- Soot Accumulation? set in the PCM.
- [2102815](/bulletins/10220462.md), 2022-09-26, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION. 8HP70 Tranmission shift enhancements.
- [21\-017\-14](/bulletins/10217981.md), 2022-08-22, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE; POWER TRAIN; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); ELECTRICAL SYSTEM. Flash: Transmission Shift Enhancements This bulletin involves selectively erasing and reprogramming the Powertrain Control Module \(PCM\) and Transmission Control Module \(TCM\) with new software. NOTE: Both the PCM and TCM must be up to date for these changes to be effective. The customer may indicate that they are not satisfied with the shift quality of the transmission. Improvements to the transmission calibration have been made to the following: Upshift Improvements ? Shift quality in Normal Mode ? Shift quality in Sport Mode ? Shift inhibit while transitioning in/out of MDS Downshift Improvements ? Downshift quality while accelerating ? Downshift quality while coasting General Improvements ? Torque converter clutch control during interlocked downshifts ? Torque converter clutch control during accelerator pedal tip in/out ? High speed gear hunting \(shifting back/forth repeatedly between two gears\) ? Allow 3rd gear launch at high altitude while in Snow Mode ? 2nd gear launch quality in ECO mode
