# Service bulletin T52

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.

## NHTSA's summary

Customer Satisfaction Notification T52 Reprogram Transmission ControlModule The vehicle speed on about 24,000 of the above vehicles maybe limited if certain conditions are met. This can occur if the vehicle is brought to a full stop and the gear shifter is immediately moved from ?DRIVE? to ?PARK? and then the key position is changed from ?RUN? to ?ACC?. This action will cause the transmission to be limited to one gear and a maximum speed of 30 ? 45 mph and will illuminate the Malfunction Indicator Lamp \(MIL\) on the instrument cluster and will set P0810 fault code. Reprogram the transmission control module.
