PO 753 AND PO502 ARE MY CODES WHAT DOES IT MEAN
P0xxx codes apply to all vehicles using the OBD2 system, P1xxx codes are manufacturer specific. Your codes mean...
P0753 = Shift Solenoid "A" Electrical.
P0502 = Vehicle Speed Sensor "A" Circuit Low.
This is possibly 2 separate issues as one is a transmission fault code and the other is a vehicle speed sensor issue. Get the speed sensor repaired first as sometimes the bad signal from the sensor can confuse the transmission electronics causing the transmission to behave strangely.

Gauges not working and all warning lights stay on.
Hi,
Please first get a free diagnosis and error codes for your vehicles from autozone. Then, you can determine which parts need to be replaced and then you can setup an appointment with a local dealership for the repair. Thank you.
1998 BUICK CENTURY CUSTOM. IS THERE MORE THAN ONE KEY THAT UNLOCKS IT? SOMEONE TRIED TO UNLOCK IT WITH KEY WITH CHIP AND SAID IT WOULD NOT FIT?
Question edited to fix the murdered spelling :>D
please don't type in ALL CAPS. It makes it very hard to read and is considered SHOUTING in Internet Land!
Question moved to sub category.
Cars of that age has a key for the door with a different keyway and no chip. The ignition key is different and has a chip.
To get into the vehicle, get underneath and put a battery charger on the + of the charger on the big red red wire terminal of the starter. Put the - on any clean bolt. Open with the key fob. Move the leads to the battery and charge it up. Then find out why the battery was flat.
