TRANSISSION STICK WHEN I STAR THE CAR AND I TRY TO GO TO REVERSE OR D. THE MANUAL STICK IS TO HARD TO MOVE.

It may just need servicing/adjusting.

Your reverse gear is actually first gear ... when you select reverse another 'cog' fits into the toothed wheels to change the direction of first gear ... to give you reverse...

It may be a sticky valve or just a bit of adjustment (workshop job..) that is required.

What you can try ..

Start the car ... move the lever through all the positions several times (foot on brake..). Keep your foot on the brake and then put it in reverse and rev the car. Hard!

Try doing it several times.

An auto transmission works on valves opening and closing. Reverse gear - in comparison with the forward gears - is seldom used. The reverse valve can 'stick'. Try forcing it to open ... frighten it ... but keep your foot on the brake...

Does it crunch? If you lift the clutch and then press it down whilst trying to get it into reverse as this lets the cogs move allowing you to slip the drive into the gears this may allow you to get it into reverse. So here's the steps:
1 start the the engine
2 drive the car for about 10 kms
3 try and get the vehicle into reverse
4 lift the clutch whilst holding the stick in the gate ( you should feel the cogs turning and shaking the stick)
5 then push the clutch down again
6 if it still won't go repeat step 4/5
if it still won't work then try and get it into reverse whilst stationary and then start the engine it will jolt but can free up the gears!

hope this helps :)

Possible transmission fluid low?

I would be looking at the selector cable ( if you have one ) for a broken cable or the end has come free of the selector . Should be under car but check both ends.

manual or stick shift?????, USA car, or not?
is the lever stuck or
the lever goes to reverse but car wont move in reverse.
2003 series 100 LC
it can be 2 things, the TCM is not commanding Reverse
or the tranny refused to go there
if A/T (automatic trans) why not, plug in any scan tool
and read all those tranny errors.
that is first after checking fuses

check under car at shift linkage may need adjustment or loose

Is the stick moving? or is it 'stuck' in the reverse position as well? There are adjustments but it seems more likely that your 'stick' has come unstuck from the gear levers that actually put the gears in the right spot. Have someone look at the transmission while you move the stick to see if the levers are moving and put your response here.

internal transmission problem. Unless you know how to rebuild a transmission it is best to take the dealr or a transission repair shop like AAMCO.

check if it has any oil in he gear box.

Is the tranny just hard to put into reverse? Check with mechanic and see if you need clutch adjusted. Also try pushing down on the shifter to bypass the safety. Most have to be pushed down from the top of the shifter in order to go in to reverse.
