Tranny jumps rpms when shifting

    I've got a 2004 Suburban with the 5.3 and for some reason when it shifts from 3rd to 4th and sometimes from 2nd to 3rd the rpm jumps during the shift like the clutch is slipping and then comes back to normal.
    Does anyone have any idea what the problem could be?
    Thank you in advance!

    Yes it's slipping. First check for trouble codes. Is it full of fluid? If so it's time to pull the pan and check the filter. Is the fluid burned?

    had same prob with my 08 this summer and it ended up being the shift solenoid

    I have a small obd2 ( got it off ebay ) and the only thing it tells me is that the system is running lean. As for the fluid it's still somewhat red i've got about 90,000 miles on it.

    Is the shift solenoid expensive? Or is it an easy fix. Please tell me it's an easy and inexpensive fix cause with four kids right before Christmas an expensive tranny prob is not a planned budge expense!!
