Check Engine Light codes P0753. Question = I have a 2003 Pontiac Grand Prix with 84,000 miles on it. My "Service Engine Soon" just came on about a month ago and when it did my cruise control stopped working as well. I can feel it has trouble shifting and I have hooked it up to a machine that AutoZone has to check my problem and it says its a transmission module (P0753).

We have asked others who say that it probably isn't the problem because they have never heard of one of those going out and it's probably a wiring issue. Can you tell me what you think it might be?

ANSWER:

This codes refers to the 1-2 shift solenoid. Be sure to check all fuses first. Specifically the "TCC" fuse in the underhood fuse block.

If that is ok, 2 things possible. Either you have a connector problem at the 20-way transmission case connector causing this code, or the solenoid. The solenoid is on the valve body in the side case of the trans.

I suggest disconnecting transmission connector with key off, look at all terminal, pull the harness a little so as to change its position, then plug it back in. Clear the codes and drive it.

Question: The factory radio clock display lights burns sometime and sometimes it want come on for a week is there a way to replaced the bulb in it instead of changing the radio out ...Thanks

Answer:
If the back lighting of the radio wont come on, there are bulbs that are soldered to the circuit board. Very tricky to replace. Usually end up causing more problems. If it is the actual display, this is vacuum florescent and there is nothing that can be repaired.
