I believe any further loss of metal on the synchro's will only make them worse.
Your synchronizers are worn out.
Sounds like you need some new synchronizers. Sounds like you need some new synchronizers. Or have you tried adjusting the cable??
HeyJoe==They are not cleanable. If it is grinding between gears, the synchronizers need replacing. GoodluckJoe
There's not an adjustment, the shifter bolts right onto the top of the transmission. If you have a problem with it poping out of gear or not going into gear you have internal problems, most likely the synchronizers. Get it rebuilt or replace it with a used transmission.
A manual transmission may not shift when the engine is running due to several reasons, including a malfunctioning clutch, low transmission fluid, or a damaged linkage. If the clutch isn't fully engaging or disengaging, it can prevent the gears from shifting smoothly. Additionally, if there are issues with the synchronizers within the transmission, this can also cause difficulty in changing gears. It's essential to diagnose the issue properly to avoid further damage.
Could be synchronizers are worn First choice is that the clutch is not disengaging, it may just need adjusting, it could be too badly worn or the clutch slave cylinder is not working, or linkage issues. Second would be major transmission internal breakage.
If you over fill a manual transmission it will blow the overflow into the spew hole in your bell housing and chances are it will get on your clutch and cause it to slip.
That only usually only happens in a manual transmission
Your manual transmission may be stuck in first gear due to several reasons, such as a malfunctioning clutch, a damaged shift linkage, or an issue with the transmission itself, like worn synchronizers. If the clutch isn't fully disengaging, it can prevent the gears from shifting properly. Additionally, check for any obstructions or debris around the shift lever and linkage. If the problem persists, it's advisable to consult a mechanic for a thorough diagnosis.
For a 1999 Toyota Tacoma, it is recommended to use Toyota Genuine Manual Transmission Fluid or an equivalent that meets the API GL-4 specifications. Many owners also opt for 75W-90 or 80W-90 gear oil, but it's essential to avoid using any fluid that meets the API GL-5 standard, as it can be harmful to the synchronizers. Always check the owner's manual for specific recommendations and guidelines.
Clutch not fully releasing, low of fluid, or synchronizers bad. You may need to adjust the clutch pedal free play.
Converting a manual transmission to automatic transmission is not possible but you can replace a manual transmission to an automativ transmission . That is also an expensive deal.
