Something to do with the torque converter lock up...Check for spark. Pull the wires off the plugs one at a time, put a screw driver in the wire then lay it where the screw driver is close to something metal and grounded. Have someone try to start it and see if a spark arcs from the screw driver to the grounded metal (valve cover, etc.) You can do the same thing at the wire/distributor instead of at the wire/plug to rule out a bad wire if that problem ever arises.
Chrysler Fault Code 37
: baro-read solenoid open or shorted
For turbocharged engines, code 37 will be triggered when the baro-read solenoid circuit is open or shorted.
For normally aspirated (non turbo) engines with automatic transmissions, code 37 will be triggered when the Part Throttle Unlock (PTU) solenoid circuit is open or shorted.
For normally aspirated cars with manual transmissions, code 37 is sometimes set for no apparent reason.
