It really sounds like a tranny problem, best addressed by a Transmission shop. It might be an easy fix, or a really expensive one.

SOURCE: It's an automatic but it won't shift from 2nd to 3rd.

I would have to say it is the tranny check the fluid make sure it is clean and at the correct level

Sounds like a bent fork in the transfer case. It is a common problem with your truck. The transfer case is a np236. If it just recently started doing this, the rebuild will cost around $800. If the 4wd has been acting up for a while, the planetary will probably need changed, which is another $200.

SOURCE: kicks really hard when shifting from park to

sounds to me like the vss (vehicle speed sensor) isnt working...its on the passanger side of the car on the top of the transmission..(just above where the right side axle is installed) youll see a 2 wire connector...sometimes they come unlpugged and when that happens no speedometer=no shifting because it doesnt know that its in motion,therefore doesnt know when or too shift..,

How many miles? Have you maintained, serviced trans in past or just waited for this day to wonder what happened?

TRANSMISSION

Fuse # 20 or 21 gets power through ignition. This fuse controls PRNDL indicator, speedometer, tach, & will cause transmission to not shift gears correctly. Ours took off in 3rd gear when put in Overdrive & only ran in 3rd gear. If we tried to manually shift thru gears (auto trans), it had 1st, 3rd, reverse. No 2nd or over drive. Replaced ignition. Fixed problem. Root problem was Electric motor that engaged 4 wheel low side was bad. Every time we used 4 Low side it threw power surge through ignition & blew ignition out. Good Luck.

2003 chevrolet cavalier, manual transmission lost 2nd, 4th and reverse but still has 1st, 3rd and 5th gears.

Sounds like one of the levers inside the transmission is either broken or otherwise disengaged. Remove the shifter to see if you can see any obvious reason.

Only runs in 1st and 2nd gear and reverse.

This is a fault mode in which the transmission either loses electrical power or the PCM deactivates all of the electronics. The transmission will default to max line pressure. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC lockup will not be available. It will not hurt the car to drive it like this for short periods, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal while operating in limp-home mode due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear.

Trans shifts into gear harshly, car feels sluggish off the line
, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmission is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the under hood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.

No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter : ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Car goes into gear but feels very sluggish like the brakes are dragging, but it will roll easily (starts out in 4th gear), you manually shift to 2 to get it moving, once it's moving you put it back in OD and the car shifts 3rd to 4th on its own and locks the converter at the appropriate time: ShiftB solenoid failed: Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

4L 60E - 2001 k1500 will not shift into 3-4. Oil is not burn't and stifts great into1-2

  • No 3rd or 4th gear: “3-4” clutches are worn out. R&R. The car is safe to drive (in 2) until you can get it fixed.
  • Trans shifts into gear harshly, car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmission is either in limp-home mode or has lost electrical power.

Check to see if your transmission is in the limp mode, which would only give you 2nd, 3rd and reverse gears. No 1st or 4th gear.

Wont shift into drive

Have you changed the fluid & filter lately? Start there, much cheaper fix than anything else.
