Re: 1994 shadow check engine code
Code 37: It means the speeds at which your transmission change gears (upshift/downshift) relative to the engine speed is out of range.
The code is set, but does not set the check engine light.
If you have the 3-speed transmission, there is a cable used by the transmission for detecting engine speed. It connects up to the gas pedal and is seperate from your throttle. A typical problem is that this cable falls off causing the transmission to shift late.
The 4-speed transmission uses a TCM and is controlled electronically.
