# Service bulletin PIP5175D 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: 10178309 - Published by NHTSA: 2020\-08\-10 - Manufacturer's number: PIP5175D - Manufacturer's date: 2020\-06\-08 - NHTSA component: POWER TRAIN:AUTOMATIC TRANSMISSION:INTERNAL:GEARS; ENGINE AND ENGINE COOLING ## NHTSA's summary This Preliminary Information communication provides information to the technician about vehicles that may have a delayed engagement into drive, shudder at a launch, or the transmission is slipping when shifting into 1st, 2nd, 3rd or 4th gears. This may be due to loose stator support to pump cover bolts causing a leak at the stator support to pump cover gasket. Technician will check for the bolts to be loose. If any of the bolts are loose or the gasket is misaligned or leaking, the transmission pump cover must be replaced and the 1234 clutch plates should be inspected for being distressed and repaired as needed. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2020/MC-10178309-0001.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2020/MC-10178309-9999.pdf) The document is the manufacturer's.
