# Service bulletin 21\-012\-12 REV. B 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: 10136470 - Published by NHTSA: 2018\-05\-14 - Manufacturer's number: 21\-012\-12 REV. B - Manufacturer's date: 2012\-11\-29 - NHTSA component: POWER TRAIN; ELECTRICAL SYSTEM ## NHTSA's summary Flash: Transmission Shift Quality Improvements This bulletin involves flash reprogramming the Powertrain Control Module \(PCM\) with new software.There may be two software packages to choose from. Both software updates will fix all symptoms/conditions listed. Refer to Service Bulletin 21\-008\-12 for details about the software choices. Some customers may notice any of the following: Harsh 1\-3 upshift while operating in Economy \(ECO\) mode. Harsh 2\-3 upshift while operating in normal mode.For 2012 model year, the harsh 1\-3 upshift in Economy Mode and the harsh 2\-3 upshift in Normal Mode was corrected in the revised software enhancements that were released in Service Bulletin 21\-008\-12 dated March 23, 2012. 1\-2 upshift clunk following a throttle back out \(2012 \- 2013 model year only\).In addition to correcting the previous Symptom/Conditions, the following enhancements have been made to improve the shift quality of the 62TE transmission: Shift schedule changes for the 1\-2, 3\-4, 4\-5, and 5\-6 upshifts and the 6\-4P, 6\-5, and 5\-4 downshifts. Fifth gear torque converter lock\-up/unlock improvements. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2012/MC-10136470-9999.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2012/MC-10136470-0001.pdf) The document is the manufacturer's.

All Promaster \(VF\) 3.6L/62TE equipped vehicles: a\) If the transmission bracket to the transmission case fasteners are removed during servicing, the fasteners \(Part Number 06511385A$\) must be replaced as they are one\-time usage. b\) Vehicles built prior to 10/23/2015 requires Service Kit PN 68461214AA; includes Transmission Isolator PN 68264483AA, and Adaptation Bracket 68264479AA and Fastener Service Kit PN 68329056AA. c\) Vehicles built on or after 10/23/2015 will require only the Fastener Service Kit PN 68329056AA. 2. Only use the reman 62TE specified in StarParts for each model year \- Only use R8210327A$ for 2014 \- 2018 VF. \- Only use R8453637A$ for 2019 VF. \- Only use R8599680AA for 2020/1VF. Installing a R8453637A$ or R8599680A$ in a 2014\-18 VF will result in a 2014\-18 MY core being returned. Mopar can no longer convert 2014\-18 VF 62TE core to the 2019\-21 version. Continued mis\-usage will result in a core shortage. Mopar may deny warranty claims where the incorrect version is used in 2014\-18 VF. 3. The engine to transmission dowel pins are critical to the longevity of several components. Verify the dowel pins are in the rear face of engine block before installing a replacement transmission. Mopar will add loose dowel pins with remanufactured 62TE. 4. All 62TE equipped vehicles. If vehicle is jerking/slipping with MIL code\(s\) P0740 or P2764, check TCC Solenoid operation. If TCC Solenoid is ok, the codes are indicative of a torque converter failure. Replace the torque converter. 5. There may be incorrect fluid measurement on the dipstick tool when checking 62TE fluid level after filling the ATF as per service library specification. Please change with new valve body pan P/N:68145886A$ as there may be incorrect valve body pan is used in Transmission. - [1805916](/bulletins/10228117.md), 2022-12-19, Service bulletin: ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING; POWER TRAIN.
