It wont go in gear - 1997 Lexus ES 300

It because of the forks inside the transmission are worn out or they have lost their plastic pieces on the fork ends.(some transmissions are built this way, plastic). you have to pull the transmission to fix it.

check for snapped or loose gear linkage cable.

automatic? trans, mines a 6speed, and has a clutch.
my guess is yes,
my A/T will not change gears,
all gears slip? (slip , flare or?)
or wont move at all. the car?????
or is stuck in1st gear in drive.?
or wont move in reverse. why not tell full story on so complex a device. super complex it is.
wont up shift , wont down shift
skips gears.
??????????????????

check fuses first.
then scan the PCM, it will tell you errors, called DTCs
use a real scan tool that can scan 2010 Jeeps. (factory codes !!!)
not some autozoned junk.

id bet there is a code, for sure.
even a broken shifter switch, or?

My 1988 HD 883 SPORTSTER WONT GO INTO GEAR. WHEN TRYING IT GRINDS When not running it wont go into gear either

you can shift it at transmission by hand to neutral or park and have someone inside start the car and you manually put in gear under hood and drive it to shop or garage, wherever

HI;
I pressed low range button and the light still on and gear change very fast o only to 3 gear wont go 4th gear how i can fix it please helpme

check for a broken cable

Do you mean you can't shift it into gear? or you can shift into gear but the car wont move?

If it is standard check your throw out bearing

most likely the shift tube bushings are bad- you may have also lost a few screws in the shift tube or they could just be loose. you have to pull the steernig column down to inspect/repair it.
