What should i do to get my 1st and 2nd gear fixed they try to go in if i push it into 1st when its althe way as far as i can push it but it wont like i knock a gear outa place or something

Well go get your car fixed by a mechanic or it something might be jammed inside

the gear grinding noise is because the clutch plate is not fully disengaging and the input shaft is still driving. If you did not use the same length of push rod then the slave cylinder is not moving enough to disengage the clutch. Check it out that with the pedal on the floor the piston in the slave cylinder should be almost to the edge of the slave cylinder . That is where It should be to be working properly

Try to double clutch when you downshift from 2nd to 1st ( while driving be in 2nd put in the clutch go to neutral pull out clutch rev it a lil and put the clutch back in and then shift to first) what this does is that it aligns the gears and it might go into 1st alot smoother. Happened to my 86 Toyota and never had problem with it after that

You can put the shifter in 2, 3, or overdrive. It will still start in first and shift up to whatever gear you have selected. Try it, you wont damage anythingl

If you'd said 1st and reverse I would have said clutch. First check your gear sgift rod for aligbnment. If it is out when you push the gear lever left to engage 1st your selector might be somewhere between 1st and 2nd. Next check all the linkage bushes for wear. Those also cause misalignment. Last thing to check is the gearbox itself for synchromesh damage.

You have a stuck solenoid in the auto, The only way to fix it is to remove the solenoids and manually free them up, This means removing the oil and oil pan and removing the solenoids.

Try to double clutch the clutch pedal. How to double clutch; push the clutch in moving the stick to neutral, then release the clutch and then push it back in and shift into first or second gear. If it works then it is not the shift linkage and could be a clutch adjustment. First how far do you have to release the clutch pedal until the clutch plate starts to engage? If only an inch or so the clutch pedal needs to be adjusted, which is an easy fix (this is more common). The other possible problems could be the clutch plate, throwout bearing of syncros could be bad. If it is one of the previous problems double clutching should buy you some time.

4L is only for slow low end torque it shoud not be used any faster than 10-15mph

Bad syncro for third gear. Sorry, but you aren't fixing this one yourself, unless you replace the transmission yourself.

It sounds like the clutch is getting worn or the slave cylinder is not pushing the pressure plate in far enough.If at all possiable try bleading the cluthch slave cylinder an see if that helps.
