At what RPM 1st gear should shift on a H2 Hummer 2003


well is that hummer that a 2 ton or 4 ton vehicle ?

would take a lot of revs for first gear to make it roll from a standing start
think it will be fitted with an 6 speed automatic transmission

guessing only from my heavy vehicle driving experiences
first should change below 3000 rpm

if transmission was slipping in first gear you would know

suggestion
ring up the local hummer service division for the correct answer

an axle problem will not increase the rpm so that is eliminated
supercharger will not make the engine rpm higher between gears so that is eliminated also
indicates a transmission problem not selecting the next ratio at the correct rpm and road speed
possible needs a transmission fluid change , clutch and band adjustment
have the fault codes read to check for faulty TR sensor or TCM failure

Check the throttle cable for incorrect adjustment with the A/C turned off. Adjust cable to obtain 850 rpms. The A/C on will increase idle speed, which is a normal function. Check the speedo cable for correct connection at the back of the transmission case. make sure hand tight at the drive.

2002 sl2 rpms very slow to drop when shifting manual transmission


Okay, check the TPS you installed for proper meshing of the components. Disconnect the throttle cable and feel action of spring for binding. Check throttle plate for carbon and dirt buildup, clean.

Now some TPS units have a slot on one end. This can correct the jump in RPM. Just slide the unit either way while the engine is running and see if it speeds up or decreases the idle position. Then tighten the mounts. There are some other adjustments possible but check for a bad intake leak.

This can be done with the engine running and using a spray bottle of water. Mist the seams of the intake gasket and around vacuum lines. Any change in RPM or stalling will prove there is a leak and allow you to fix it.

It is kinda simple. A air leak is like opening the throttle to let more air in. The engine will run faster. Correct the leak and the idle should be reduced.

The RPM of 2007 Nissan Altima stays high when drive over 65 MPH.


It sounds like the trans is not reaching Overdrive final gear, this is controlled by the computer that shifts the transmission. What needs to be done now to see what is keeping it from shifting into OD is have the Transmission control module (TCM) scanned for fault codes by the dealer or a shop that has the correct electronic scanner for reading the TCM.

The transmission is controlled by the Transmission Control Unit (TCU).

Throttle position, rpm, and speed are input parameters to the TCU. The TCU has a default set of shift patterns. These shift patterns change over time based on your specific vehicle setup and driving habbits.

The shift patterns are only slightly affected by driving habbits over many driving cycles. But, changing the relationship between the throttle position and the actual speed being reported by the speed sensor can have an immediate effect on shift patterns.

While your speedo may now be correct, the realtionship between rpm and thottle position has not been corrected. That would take a gear change in the differentials.

The TCU can be reset to an inital learn base line. When this is done, the TCU will instantly learn the dynamics of your setup.

Any shop with an advanced ODB scan tool can reset the the TCU. The dealer or a transmission shop would be preferable.

You really should change your differential gears as opposed to resetting the TCU

Gears aren't shifting...RPM's too high


There is a problem with the transmission sensor on these cars that will set a trouble code and cause the problems that you describe. Another issue is the correct fluid, use ATF+4 in your Intrepid or you'll mess up the transmission.
