To stop a standard transmission from grinding into third gear, check the level of the Transmission Fluid. If the noise continues, consult a mechanic.
I assume you are referring to a manual transmission. Grinding while changing gears is an indication of a synchronizer going bad. Until you get it fixed, try double clutching when shifting.
missing teeth on third gear
If it's only when you attempt third gear the problem is in your transmission.
Could be low fluid,a bad sensor or transmission going bad.
If your transmission is not shifting into third gear and overdrive it could be a parking pawl. This prevents the transmission from rotating.
The standard notation of 6.17 times 10 to the third = 6,170
Your transmission synchros might be going out. Also, shift slower and see if that helps. A Jeep isn't a racecar, so shifting slower is easier on the transmission. Changing transmission fluid to a different brand might also help your problem.
Yes it can minor grinding may be required
3rd gear is bad,must put new gear in or replace transmission.
9.11*103 IS in standard notation.
33 is 27 in standard notation.
just third gear most likely trans damaged could be dragging clutch if in other gears also
