Transmission
Brunner Ferdinand Hello,
greetings to you, My Hummer H2 Year of construction 2004 6.0 L I rebuilt my gearbox and reinforced it. Shifts flawlessly and great, but the converter lock-up lets my engine speed move up and down by about 200 rpm. Only when gliding. The second thing is: if I turn up to 4000-5000 rpm, I have a short squeak when the 3 or 4 gear is engaged. Can someone help me there. Thanks in advance. :confused: |
Sounds like the fluid clutch in the torque converter may have a problem or possible lockup converter solenoid is not functioning properly. A transmission shop should be able to identify the exact cause using an OBD2 tool such as a Tech 2.
How clean is your fluid, that is a good indicator of your transmissions health. You need to get it diagnosed as soon as possible. |

It goes up to 4500 rpm like a new gearbox.No errors are saved. |
