Is it missing reverse 2nd and 4th? If so it has a broken reverse reaction shell. They aren't too hard to replace

SOURCE: 4l60e trans. will not shift out of 3rdgear...

Have it scanned. Have the person who scans it pay particular attention to the Transmission temp sensor. If the Transmission temp sensor tells the ecm the transmission is cold, it won't shift to 4th. Also if it thinks the transmission is too hot it won't allow a 3-4 shift.

SOURCE: changed trans fluid and filter and in the process

Try disconnecting battery for about a minute and reconnect.

SOURCE: 2003 trailblazer ext will not shift into 3rd

Seems as if you have Covered all PRELIMINARY Bases, So Next step I Would Advise that you Visit a Transmission Repair Shop For A "SYSTEM FLUSH" This Flushes the Hydro system in Trans and Could Free up Any Debris that Potentially Cause Shift Failures and Other Problems. I Hope this HELPS you, Those Transmissions Can QUICKLY Become MONEY PITS

2000 silverado wont go into passing gear


Check the A and B shift solenoids in valve body. A combination of either solenoids on or off gives 4 speed selection. For instance all solenoids off gives 3rd gear for limp home. Sounds like 1 solenoid is off all the time for no 1st and 4th. Check solenoid chart to see which solenoid is on for 1st and 4th. That solenoid is either not turning on or a wiring connection between the transmission control module and that solenoid.

My 2000 Nissan Xterra will not go into 3rd 4th or 5th gear


In the installation of a new clutch in most instances it is necessary to remove the gear lever from inside the vehicle . Check that you have the end of the gear lever actually situated in the groove that lines up all the shift rails as you may have placed the end outside the groove and can move only one rail. You have given no indication of a clutch problem at this stage so I am sure that is where the problem will be.

Transmission module


shift solenoid is not the only part to make it shift. there is valve inside the valve body. pcm can say no first gear because a code is set

I have a 1998 dodge Grand Caravan with codes P0700,P0734 & P0733. What does this mean?


P0700 is a informative transmission code, about some problem there; the P0733 and P0734 is the specific problem there.
I would first try changing the fluid and filter. Although the fluid may look like it is brand new, with 100K on the fluid, I can assure you that even if those miles were all highway at steady speed and no load that the fluid has deteriorated and no longer lubricating the internal parts properly and that there is some debris in the ******.If codes return and shifting problems are still present, there is definite internal failure, possibly the pump or in the clutches.
DTC P0733The powertrain control module (PCM) uses the crankshaft position (CKP) sensor, input speed sensor (ISS) and output speed sensor (OSS) to determine engine speed, input shaft speed and output shaft speed. These sensor readings are used to determine the current gear ratio and RPM slip across the torque converter. The PCM uses this information from the sensors to determine if the commanded gear matches the actual gear. During normal driving conditions, the PCM will adapt main line pressure via the pressure control (PC) solenoid to prevent slipping and harsh shifts. Shift solenoid 3 is used to apply or release third gear clutch. The PCM controls 3rd gear by controlling the ground for shift solenoid 3. The PCM will turn the solenoid OFF, open the driver circuit, when 3rd gear is commanded On to apply 3rd clutch. Shift solenoid 3 is supplied ignition voltage from the fuel pump relay whenever the PCM commands the fuel pump relay ON. DTC P0733 sets when 3rd clutch still slips after the PCM has commanded high main line pressure.DTC Parameters
DTC P0733 will set if the PCM detects an incorrect actual 3rd gear ratio when 3rd gear is commanded On when:- The condition exists for longer than 3 seconds (2001)*- The condition exists for longer than 3 seconds, 1 minute is allowed to elapse, then condition exists again for longer than 3 seconds (2000)- The high main line pressure has been commanded- The transaxle is in a forward gear- The input speed is greater than 224 RPM- The vehicle speed is greater than 5 km/h (3 mph)- The speed noise parameter = NO- The steady state ratio fail counter equals 255 for an in-gear failure, or the shift fail counter is greater than 100 on a downshift or upshift to 3rd gear (128=0 or normal operation)DTC P0733 diagnostic runs continuously once the above conditions have been met.
DTC P0733 is a type A DTC for 2000, type B for 2001.**Applicable to vehicles built after June 2000.
Diagnostic AidsImportant: If DTCs P0745, P0746, P0756, P0758, P0761, P0763, P0766, P0768 or P0789 is set, diagnose that DTC first. A diagnosed PC solenoid, shift solenoid 2, 3 or 4 low/high circuit fault DTC may have caused DTC P0733 to set.Important: If a shift solenoid performance DTC P0783, 4th gear stuck ON, is set, diagnose that DTC first. A 4th gear stuck ON may cause no 3rd gear, no 2nd gear, or TCC stuck Off.
Refer to Pressure Ports - Air Check and Parts Description for pressure apply points and for component/location description.
Possible causes of no 3rd gear are listed in the flowchart on the succeeding page.
Verify TRANSMISSION ISS and TRANSMISSION OSS read correctly on Scan tool.
Make sure the pressure control, shift 2, shift 3 and shift 4 solenoids are not intermittently sticking. A sticking shift solenoid 4 may cause 4th gear to be applied from an initial start resulting in no 3rd gear. Audible sound should be similar for all solenoids. A muffled tone indicates the need for replacement.

P0734 refer at ratio 4 gear, and the rocedure is the same.
Hope helps.

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.

Transmission overdrive is not shifting


any transmission fault codes? this trans is electronically shifted so there should be a fault code for the problem, have it tested. Any Kragen or Autozone can run the test for free

Shift solenoid relay.. internal or external?


Trans model is the 4L60E,and the shift solenoids are mounted on the valve body,just inside the bottom pan.There are 2 shift solenoids,one EPC solenoid (Electronic Pressure Control)One TCC PWM solenoid (Torque Convertor Clutch,Pulse Width Modulated),one 3-2 kickdown solenoid,and a manifold pressure switch.As far as a shift solenoid relay switch,i have never heard of that.The power for the transmission solenoids comes through the ignition switch ,and uses a fuse,not a relay.Accessing the solenoids only requires dropping the bottom pan,and the valve body does not have to be removed,to change the solenoids.The shift solenoids are the TWO solenoids right side by side and look identical..They are the only two solenoids inside the pan that are in fact identical.Good luck.
