Transmission fluid levels

[Hylander]

It’s a little frustrating with the problems with the transmission shop in the Chevy truck that you can’t check your fluid levels. Is there a kit you can buy aftermarket allows you to put a dipstick in or at least change the fluid without going to the dealership? Any information on this would be helpful I’m frustrated by it and looking for a solution!!!

Not sure which transmission you have. I remember reading that guys were getting the dipsticks from cars like the Corvette and Camaro and installing them in their trucks.

You can check your transmission level, its just not done with a dipstick anymore.  

Caution: THE ENGINE MUST BE RUNNING when the trans oil level check plug is removed or excessive fluid loss will occur, resulting in an under-filled condition. An under-filled transmission will cause premature component wear or damage.

Note: Continue to monitor the TFT. If the TFT is not within the specified values, reinstall the trans oil level check plug and repeat the previous steps.

1. Observe the TFT using the driver information center (DIC) or a scan tool.
2. Start and idle the engine.
3. Depress the brake pedal and move the shift lever through each gear range. Pause for at least 3 seconds in each range. Move the shift lever back to PARK. Ensure the engine RPM is low (500–800 RPM).
4. Allow the engine to idle for at least 1 minute.
5. Raise the vehicle on a hoist. The vehicle must be level, with the engine running and the shift lever in the PARK range.
6. Remove the transmission oil level check plug (1) from the transmission fluid pan. Allow any fluid to drain.

   • If the fluid is flowing as a steady stream, wait until the fluid begins to drip.
   • If no fluid comes out, add fluid until fluid drips out, refer to Transmission Fluid Fill Procedure.
