# Service bulletin 16\-98\-16

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: 10084141
- Published by NHTSA: 2016\-11\-08
- Manufacturer's number: 16\-98\-16
- Manufacturer's date: 2016\-02\-05
- NHTSA component: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\)

## NHTSA's summary

THIS BULLETIN ANNOUNCES AVAILABILITY OF REPROGRAMMING FILES FOR OPTIMIZATION OF THE TRANSMISSION CONTROL MODULE \(TCM\). THE NEW LOGIC ADDRESSES CUSTOMER CONCERNS OF INCONSISTENT SHIFTING CHARACTERISTICS AND / OR A “SLIPPING” \-TYPE SENSATION WHICH MAY BE EXPERIENCED UNDER MODERATE ACCELERATION AFTER A COLD START BEFORE THE CVT IS UP TO OPERATING TEMPERATURE.

- [16\-103\-16R](/bulletins/10154206.md), 2019-03-11, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION. This bulletin has been developed in response to a small number of customer concerns regarding fluid seepage found coming from the CVT assembly. Investigation has identified a likely source of the seepage to be the sealant used on the CVT?s oil pump chain cover. The repair involves removal, a thorough cleaning and inspection of the sealing surfaces followed by re\-sealing the cover.
- [16\-100\-16](/bulletins/10140512.md), 2018-06-11, Service bulletin: ENGINE; EQUIPMENT; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). This bulletin announces availability of reprogramming files to optimize the TCM. The files will address customer concerns of inconsistency in the amount of engine braking experienced when using Manual mode \(or paddle shifters if equipped\) when descending long downgrades. 2.5L NA models.
- [16\-90\-13R](/bulletins/10140492.md), 2018-06-11, Service bulletin: POWER TRAIN:CLUTCH ASSEMBLY:PEDAL/HAND LEVER\(MOTORCYCLE\); ENGINE; EQUIPMENT; POWER TRAIN:AUTOMATIC TRANSMISSION:TORQUE CONVERTER; POWER TRAIN. CVT Transmissions only. This bulletin announces the availability of a countermeasure torque converter assembly to address a customer concern of very low engine RPM when coming to a stop. The condition is similar to coming to a stop in a manual transmission equipped vehicle without depressing the clutch pedal. Thrust washer wear inside the torque converter can cause restriction of the oil passage used to bleed off lock\-up clutch application pressure. The result is either a delayed \(momentary low engine rpm\) or no lock\-up pressure release. The thrust washer has been changed from a solid bushing\-type to a needle bearing type.

- [WQW\-58R](/bulletins/10117558.md), 2017-09-14, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); ELECTRICAL SYSTEM. 2.0L DIT Models Only. Subaru of America, Inc. has determined that vehicles affected by this Service Program require ECM reprogramming. This bulletin includes the service procedure for diagnosis and repair of customer concerns involving engine idle roughness or, in some cases, engine noise and/or damage resulting from spark knock \(pre\-ignition\). The Engine Control Module logic has also been optimized requiring the ECM reprogramming.
