2002 Saturn Lseries trouble putting into gear at starup.

Best to have a shop listen to this, intelligent noise assessment requires ears on diagnosis.

It could be a bad coil assembly, or dirty fuel injectors. I would look at the coil box first.

there is a emergency brake shoe inside the rotor and there is a brake pads too

Are you putting it in the right gear? The vehicle sounds like its getting into the wrong gear.Does the shifter feel like there is alot of play? you may have a gear linkage problem,and do you have trouble getting in reverse if so you have a linkage problem

Dear Pll,
If you have to ask, you should not try to do it!
Your life and that of other road users depend on it!
I found that many new cars make it very difficult to work on the brakes!
That is for a good reason!
It is to keep amateurs out of them!
I know that the so called experts ripp uss off!
I hate that, but I suggest you look for a retired mechanic, someone like myself who is battling financially and have the expertise to help ypou by howing how to do it under his supervision.

Is it only when you go from park to reverse? Or is it just as bad going from neutral to reverse? I've noticed on mine that it's often tight if I park on even a slight slope. If it only happens when going from park to reverse, try this. Hold your foot on the brake, and put the car in drive. Keeping constant pressure on the brake, go back to park, then back into drive. Did you feel the stiffness when you had your foot on the brake?

You have a slave cylinder for this trans. Pump the clutch pedal 25 times with the engine OFF. Then start it and try shifting it into each gear while parked. If this make it work your slave cylinder needs to be replaced

IF IT STUCK IN PARK.CHECK BRAKE LIGHT SWITCH FUSE AND THE BRAKE TRANSMISSION SHIFT INTERLOCK SOLENOID FUSE.AND PARK NEUTRAL SAFETY BACK UP SWITCH FUSE.IF ANY OF THESE 3.IF FUSE IS BLOWN OR ANY IS FAULTY.YOU WONT BE ABLE TO MOVE CAR OUT OF GEAR.ANOTHER THING MAKE SURE YOUR BATTERY HAS 12.5 VOLTS.

check power to the reverse shift solinoid

Simply drive in reverse to about 5 mph and mash on the brake pedal to stop. You only have to do this once and the brakes will automatically adjust themselves (assuming everything was reconnected properly).

I hope this helps.
