tranny slipping

i have a 2005 z71. i noticed that the tranny would only go into 1st and 2nd gear. no 3rd or fourth. all other gears are fine. i haven't found any leaks and i haven't checked the filter yet but the fluid level is good. any ideas?

What is the mileage and engine and transmission?
Slipping or just no shift?
Any check engine lights?
Get it on a transmission capable scanner and read out shift data and check shift solenoids.
Check for codes and post back code no.

its at about 70,000 miles. it won't shift into third or D. no check lights at all. i live on base in germany and i dont think the hobby shop has diagnostics but i'll ask them. being overseas, i had to order a filter/gasket so i can't drop the pan yet.

the previous owner (also in germany) drove it kinda hard, we do use the autobahn everyday, and its seen some mud a couple weeks ago. i think i may have gotton some dirt and water in it somehow.

also check the wiring to the/at the transmission ....and the connector pins etc for damage....fluid good with no 3 or 4th gear...


If it slips your probably gonna have to rebuild it ,,, fluid should be damaged...though..

I'm now having this same problem, no D or 3, seems to be slipping.:eek:
