Question about Cars & Trucks

Open Question

4t65e transmission in 2004 Impala not shifting into 3rd gear.

Trans shifts fine 1-2, but stays in 2nd gear up to 45mph,when you let up on throttle trans shifts into 4th gear. If you let vehicle slow to 35mph and apply light pressure to the throttle trans shifts in to 3rd gear, then shifts up in to 4th gear,& Torque locks up. I get no codes, changed filter & refilled w/Dextron III fluid. Problem still persist. Problem is same hot or cold. Could this be caused by the Pressure control solenoid, or a sticky accumulator piston?

SOURCE: transmission won't shift to 2nd and 3rd gears goes from 1st to 4th.

Doesn't sound like a simple fix. I would suggest having it serviced.

SOURCE: trans drops into 3rd gear won,t shift to 4th

DTC P0734 is "4th gear incorrect ratio" - that's your torque converter 'LOCK UP Clutch" It's worn out (or you're using the wrong Trans Fluid required by Hyundai - SPIII OR Both). The P1624 is simply the Trans Control Unit (computer) communicating to the Engine Control Module (ECM computer) MIL - on request signal to ECM = asking it to turn on "Check Engine" light. MIL = Malfunction Indicator Lamp. When the torque converter 'lock up" clutch slips or doesn't engage, the trans automatically returns to 3rd gear and stays there (it's called 'fail safe' mode) until you cycle the ignition key, then everything resets until the malfunction occurs again.
You'll need to have an AT (Automatic Transaxel) tester hooked up to verify this. Hyundai has a Service Bulletin specifically for "gear incorrect ratio' codes. If when you changed the trans fluid, was it done at a Hyundai Service Center? If not, someone may have installed the wrong fluid.

I have a 2004 Envoy slt 4wd auto....The car will shift fine from 1st to 2nd gear but rpms climb and it does't go to 3rd. I tried to maunually shift through gears, but it still doesn't get 3rd?


its most def a purely transmission issue i believe its the solenoids. have it taken to a reputable trans shop near and have them diagnose it with there speciall code reader.

CHECK TRANSMISSION FLUID LEVEL FIRST BUT IT SOUND LIKE YOU NEED A FLUID AND FILTER CHANGE IF TRANSMISSION FILTER STOPPED UP TRANSMISSION PUMP CAN DRAW FLUID THROUGH CLOGGED FILTER.WHEN ENGINE AND TRANSMISSION GET HOT FLUID WILL GET HOT AND THIN ENOUGH TRAVEL THROUGH FILTER SO CAR CAN SHIFT INTO OVER DRIVE.DO A FLUID AND FILTER CHANGE SEE WHAT HAPPENS.

Could be water that touched one of your electronics that makes your transmission having problems try to dry the Transmission electronic connectors with low air pressure and see whats happens.Good luck

Sounds like your transmission is in limp mode. 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.

The other from what you described, 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.

Thank you for using fixya and have your Safari scanned for the DTC codes that would indicate what issues your transmission is having to put you in to limp mode.

This is common problems to the transmission when the fluid is getting to dirty and the transmission fluid and filter needs to be replaced. The transmission fluid and filter should be replaced every 45,000 miles to ensure there is no dirt causing the shift servos from binding. The other thing to is that when the transmission fluid get's to dirty, the fluid gets thicker. It retains fluid retention which can cause conflicts in the transmission sensors. What your experiencing is, your transmission is not shifting back to first gear and sticking in to 2nd gear. When you get on the gas peddle, the transmission sensors realize that it needs to be in 1st gear, so as the engine's RPM goes up and the transmission drops back to 1st, you get the jerking condition which will in turn cause you a $2,300.00 transmission replacement. For now when starting off from a stop, let the engine creep forward on it's own first to ensure that the transmission has shifted in to 1st gear. Then get on the gas peddle lightly till you have the transmission serviced. $100.00 transmission service is better then $2,300.00 transmission replacement. Good luck and do not have a transmission fluid flush, just filter and fluid replacement.

2000 impala ls trans problem


The problem is a known issue with the 1 to 2 shift at hard throttle. The fix is a repair of the entire 2nd clutch assy. in the transmission. There is a TSB about it released by Chevy. It will need that rebuild for the sudder to go away, or you can try and let off it at shift to stretch more miles out of it.
