Transmission won't shift into gear. Fluids fine. Starts out grinding then slowly goes into low gear doesn't shift in drive. Rhonda in Slater

i would be checking the shifter cable adjustment first see how that goes goodluck

Do the old additive method before you give up....................add one and a half cans of `Sea Foam TRANSMISSION TREATMENT' to it and follow directions. Sometimes that can of stuff is AMAZING! don-ohio

if the gears were "melted together" then the trans wouldn't shift at all. since the car runs fine sometimes and sometimes it doesn't it sounds like an electronic problem. the trans uses shift solenoids to acheive gear changes. is the fluid dark brown in color or smell burnt? if so you may have some slipping of the clutch discs/ bands, but it doesn't sound severe if the car runs fine at times. i suggest you have a trans shop to drive the car and get a more accurate diagnosis.

if the fluid is to low it will not engage

CHECK TRANSMISSION FLUID LEVEL AND TV SHIFT CABLE ADJUSTMENT BUT COULD BE LOW.IN FLUID LEVEL OKAY. YOU COULD HAVE FAULTY VECHICLE SPEED SENSOR OR FAULTY SHIFT VALVE OR SERVO BUT HAVE CAR CODE SCAN FOR TRANSMISSION FAULT CODES.

4l60e or 4l80e transmission?

manual?? put it in first gear --hold foot on clutch and start engine ,car will shoot forewards but do not be deterred drive car with foot on clutch and after a short distance the clutch will clear and the engine will rev up ,now release the clutch and drive as normal ,it will be ok from now on

Give a try by change your transmission/filters and Transfer case oil.

sounds like first gear is shot.if so you got three choices one is to take to trans. shop ,repair yourself,or buy used trans and do a fast swap.
