# Service bulletin 34 13 16 2034108

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.

Diagnostics in the gearbox control unit sporadically prevent the first selection of the reverse gear. Customer may report that reverse gear sporadically cannot be selected. A message in the instrument panel may read "Please use brake and select gear again". Reverse gear can then be selected. The complaint cannot always be reproduced. Faults are not stored in the transmission control module \(TCM\) \(address word 02\) or in the TCM 2 \(address word C2\).
