I have seen adjusters on the console shifters for GM. You have to remove the handle and pull the bezel and boot off the shifter. Where the cable is mounted to the bracket/ floor, there is some adjustment. But there isn't enough to adjust for what your's is doing. This adjustment is for the shifter handle more than an adjustment for the range. The only thing I can think of is that the shifter arm on the transmission isn't in the right position, mounted to the transmission.. Any thing else wouldn't work.

check and adjust the position of the new switch . It may require a friend to tell you when the switch is in the correct position in relation to the indicator.

is your blazer an s-10 blazer or full size. if you already have a shifter on the floor you may be able to easily do it though you may need a new adapter plate that mounts in between the tranny and the t-case.

I will try to help.
I would get someone to shift the shifter inside to the park position to see the direction underneath of the
shifter on the tranny. Then loosen the cable to the
shifter on the tranny move the shifter on the tranny to the same direction you seen toward park to the last position on the shift mechanism. That should be the park position. now put the shifter in the park position and tighten and/or reattach the cable. you should be good now. Hope this helps

Hope this helps and thanks for using FixYa!

replace the shifter assembly.I replace alot of them.use this bulletin as a reference.Subject: Various Concerns With Shifter and/or Ignition Key (Replace Shifter Assembly/Shifter Components or Ignition Lock Cylinder )


Models: 2005-2008 Chevrolet Cobalt

2005-2006 Pontiac Pursuit (Canada Only)

2007 Pontiac G5

with Automatic Transmission 4T45-E (RPO MN5)

Some customers may comment on any of the following concerns:

• The shifter is hard to move or binds.

• They cannot remove the ignition key.

• It takes high effort to rotate the key.

Cause 1
The shifter button may be sticking in the handle.

Cause 2




The pin that activates the micro-switch may have moved out of position (refer to illustration above). This causes the micro-switch to fail to engage when the vehicle is placed in Park. If this condition is present, the customer will not be able to remove the key from the ignition.





The illustration above shows the switch in a correct position.

Cause 3
Metal flashing left in the cylinder may cause a high effort to rotate the key.

Cause 4
The slider may be binding in the guides. This may cause the shifter to become difficult to operate.

Correction 1
Verify that the shifter button is inoperative by evaluating if the park pawl pin on the shifter assembly moves when activating the button. If the parking pawl does not move when the button is activated, the shifter handle will have to be replaced. Refer to Floor Shifter Control Knob Replacement in SI.

Correction 2
Important: A change has been made to the shifter assembly for service. The replacement shifter assembly will read PRNDIL (Park, Reverse, Neutral, Drive, Intermediate and Low).

Verify that the micro switch is out of position. Replace the shifter assembly. Refer to Transmission Control Replacement in SI.

Correction 3
Important: Refer to instruction sheet that is supplied with the lock cylinder kit. BO 47869 is an essential staking tool and must be used for the repair.

Replace the ignition lock cylinder. Refer to Ignition Lock Cylinder Replacement in SI.

Correction 4
Replace the slide indicator and guides in the shifter following the procedure below:

Apply the parking brake.
Remove the upper console trim. Refer to Trim Plate Replacement-Console Front in SI.
Remove shifter knob. Refer to Floor Shifter Control Knob Replacement in SI.
Remove the indicator plate. Use a flat-bladed screwdriver to release the locking tabs.
Remove the shifter indicator lens.
Pull up on the indicator and remove it from the assembly.
Remove the two front rails by unsnapping the front and lifting up, and then back, to remove the rails from the shifter assembly.
Install the new guides. Place the hook end into the assembly and push down. It will snap into place.
Install the new slide indicator. With the transmission in neutral, place the slide over the shifter and into the guides. Move the slide indicator down the guides in the front and rear.
Important: Replace the shifter indicator lens if damage is present due to the slider binding or if it becomes damaged during disassembly.

Install the shift indicator lens.
Install the shift indicator plate.
Install the shifter knob. Refer to Floor Shifter Control Knob Replacement in SI.
Install the upper console trim. Refer to Trim Plate Replacement-Console Front in SI. post back with what you find.
