Auto Tranny Issue In Park

[MikeyGT]

Hi Guys,

I got a question for you guys. For Auto tranny cars, if your car is in a motion type gear like R N or D, and you move it to P, does the P light turn on before you let go of the brake or after?

The issue I'm facing, especially on elevated ground is that, when I shift my gear to P,
1. the light doesnt turn on until i let go of the brake, or
2. it turns on after a second or 2, or
3. no light shows. In that case, i hear a grinding or uneasy sound.

Sounds rhetorical but is this normal?

Thanks

Just tried this myself on both a flat and inclined driveway at my office. In both cases the light turns on when the shifter goes into Park. Having my foot on the brake pedal doesn't have any effect.

I think you should have it looked at.

[MikeyGT]

I'll let you guys know what the verdict is. Hopefully Toronto Mazda can find the issue and fix it

So i finally found time to bring my car in for a check up.

The problem was.. according to the invoice, transmission range switch internal failure. They replaced the switch.

Not sure what this all means but car feels awesome now. I'm one happy camper

the switch will NOT fix the issue
they need to look at TSB 01/08-40

2004 - 2008 MAZDA3 - ENGINE WILL NOT START IN P-RANGE INTERMITTENTLY

APPLICABLE MODEL(S)/VINS

2004-2008 Mazda3 vehicles with VINs lower than JM1BK**** ** 848579 ( produced before November 1, 2007)
DESCRIPTION

On some vehicles, the shift position lamp in the instrument cluster does not come on in the “P” position, and the engine does not start. However, the engine can be started in the “N” position. This is due to rust on the connecting point of the shift cable and lock cable lever causing the select lever not to move to the location where it is recognized as “P” range. There is no issue about the transmission reaching Park. This is only an issue about confirming “P” indicator in the instrument cluster. A slit on the mud guard has been removed to prevent salt water from getting to the location where rust would occur.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE

1. Verify customer concern.
2. First verify that rust appears on the connecting point of the shift cable (A) and lock cable lever (B), then replace the lock cable lever with modified one by removing the nut (C) and washer (D). Also, replace the nut and washer. NOTE:


When removing or installing the lock nut, always be sure to hold the lock cable lever with an adjustable wrench. Failure to use an adjustable wrench may cause TR switch breakage.
If corrosion is present, apply penetrating oil to the shaft and nut threads before loosening.
When loosening, if there is binding because of corrosion on the threads, work the nut back and forth until it comes off.
Tightening Torque: 31.4 Nm (3.2 - 4.7 kgf-m, 23.2 - 33.9 ft. lbf.)


3. Verify repair.PART(S) INFORMATION

the new selector arm appears to be zinc plated with a trivalent chromate surface treatment (because it looks blue), whereas the original part is appears to be just zinc plated with dichromate surface treatment

someone actually mentioned to me this earlier but i never had the second part, the car not starting up on P.

Also, my VIN doesnt match what you mention but thanks

your car is an 07, so I still doubt that your car is not affected
