Well, you have a gasket leak around the trunk lid is my opinion. Check the rubber seal around the lid for tears or missing pieces. You can get a new gasket at any parts store. And a wet vac will take care of the water in the trunk. Good luck

List of possible reasons: Restricted flow of the filter inside the Transmission, defective shift solenoid also inside. Defective transmission control module. Have them all checked

Do you know what fuel pressure regulator is ? These like to leak when they get older !
The cartridge type fuel pressure regulator (1) is a diaphragm-operated relief valve (6) with fuel pump pressure on one side, and regulator spring (2) pressure, and intake manifold vacuum on the other side. The regulators function is to maintain a constant fuel pressure across the injectors at all times. The pressure regulator compensates for engine load by increasing fuel pressure as engine vacuum drops.
The cartridge regulator is serviced as a separate component. When servicing the fuel pressure regulator, insure that the O-ring backup, (3) large O-ring, (4) filter screen, (5) and small O-ring (7) are properly placed on the pressure regulator.
It's located on the fuel injector fuel rail !

The Vehicle Speed Sensor (VSS) is a gear-driven permanent magnet generator housed in the transaxle. The sensor generates a sine wave output with a frequency proportional to the vehicle speed. The Powertrain Control Module (PCM) converts the signal to an output that switches to ground at a frequency of 4000 pulses per mile. The signal (CKT 817) is used by various vehicle components. The signal CKT 817 drives the following components:
Is your check engine light on ? More then likely it's what is called a stepper motor ! This stepper motor is inside the instrument cluster behind the speedometer gauge an is electronically controlled ! They are fixable , gm has had problems with certain ones ! The thing I do is hook up a scan tool that allows me to check it an check for DTC'S - diagnostic trouble codes ! You could get one from a car salvage place $ 10- $20 , the whole instrument cluster !
