Could be the switch on the trans or the pump may have went out, or something is wrong with the valve body inside the trans

In my 95 GMC Sierra 1500 4x4 just had the transmission rebuilt 3 weeks ago I was driving down the road and it shifted 1st to 2nd fine but from 2nd to 3rd it reved up all the way to 4500 rpms before...


That could be a perfect reason to take it back to the shop where it was just repaired for repeat service. Either that or you spun out in the mud.

What could my problem transmission only moves when I shift it through 1st,2nd, and 3rd


Valve body. You have a sticking valve. When you manually shift it into first, you force the sticking valve to move(pressure). There could be a couple other problems, But they are still in the valve body.

The transmission is shifting hard going from 1st to 2nd and from 2nd to 3rd on my 1998 GMC sierra 1500 4x4 5.7 liter. This does not happen until about 15 to 20 minutes of driving. Before that the...


rec check fluid first. If trans fluid hasn't been changed in last 30,000 miles change fluid, filter and pan gasket. At that time inspect for foreign materials in bottom of pan or on magnet if you have one. If truck has over 100K and fluid was never changed you may have more problems if changing the fluid.

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. 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 : Shift A solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.
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.

Transmission wont shift into 3rd gear.


I had this exact problem on my 2005 5.3L Suburban... It would shift into 1 and 2 and reverse, but not 3 and 4.

I took it into a transmission shop, and he said the 3-4 shift solenoid was burned up. Wanted 1500 to fix it. Far from home, so I have to pay it.
