No 3rd or 4th on 2003 chevy tohoe 5.3 ? - Tahoe Chevrolet Cars & Trucks

sounds like your clutch needs replacement

From what you are describing, it is possible either the 3-4 actuator is no longer playing with the 3rd & 4th clutch packs, only way to know for certain is to hook up the good ol' pressure gauge to trans. system, yeah, you think the Chevrolet dealer should know this right?

Sell it now if you can!

USE A SCANNER TO CONFIRM WHETHER HAS ANY SOLENOIDS HAD TO DO WITH.

the torque specs for your intake are the first pass to 44in/lb the second pass to 89in/lb. and the tightening sequence is as follows:
start on the passenger side (right side) the 3rd bolt (from front) is #1 then on the driver side (left side) 3rd bolt is #2 and 4th bolt is #3.Back to right side 2nd bolt is #4 and 4th bolt is #5. Left side 2nd bolt is #6 and 1st bolt is #7. Right side 5th bolt or rear most bolt is #8, left side rear bolt is #9. Then finish with right side 1st bolt is # 10.

Do that the first time at 44 in/lb then same thing over again at 89 in/lb

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.

Good luck and thank you for using fixya

an evn better fix if its playing up is to fit a manual gearbox

Normally while driving in overdrive (4th gear) you will feel it start slipping and finally slide into third gear. Then 3rd gear slips out into second, and you will never see 3rd or 4th gear again. I'm guessing this was the problem? If so its time for an overhaul

Hi:

Your transmission has 3 shift rails...
1st - 2nd
3rd -4th
5th- Reverse

If your 3rd gear doesn't work , you have an internal transmission problem, such as a syncronizer, or similar fail... There is not much you can fix, without removeing the transmission.

you have a valve body problem, some of the speed sonsor controls are malfunctioning... need to get into the valve body... check fluid condition for dirty and burned condition...

with the shifting lever there are bushings, you just need to replace them.
