GENERAL INFORMATION
MPH), the transmission will immediately
substitute second gear for the current gear. If
the gear ratio problem goes away, normal
operation will resume. If three gear ratio
problems are identified in a given key start,
the transmission will go into Limp-in mode.
Possible causes:
Code P0736(50) - Excludes geartrain failures
which should be obvious upon disassembly
> If code P0944(35) is also set, follow diagnostic
procedure for code P0944(35) first
> Valve body - #1 ball check or LR switch valve
sticking - may also set code P0731(51)
> Speed sensor or associated wiring - may also set
codes P0731(51), P0715(56), or P0720(57)
> Failed or slipping LR clutch - may also set code
