ODB Code P0700/0796
Hello,
I'm new here, and as i'm french, my english is not very good and i'm sorry if i write badly. Please excuse me.
My Corvette is a 2006 LS2 model, with a 6 automatic gear.
It have 47500 km and i have a code O796. I can erase it, but it come back quickly, when the gear try to jump to 3rd to 4th. And at this moment, the gear stay blocked on the third shift. I don't know what to do, and unfortunately, nonody knows in my country what to do.
It seems to be the solenoid to have being changed, but how can i be sure about that ?
I would like to know if it's a 6L80 or a 6L80E model ?
Thank for your answer, and sorry if i'm not clear to read.
I'm a member of a french Corvette club, and we love our 'Vette, but hard to find answer sometimes...

The P0796 is pretty rare, so not much info about it.

Thank's for the link RicK T, I found it :
P0796 - CBR1/4-5-6 clutch regulator valve (327) in the upper valve body (321).
So i ordered the Upper valve body complete, because i can't order the solenoid only.
This solenoid command the 4,5,6 shift. And as my car doesn't drive beyond the third gear, i suppose it's the right diagnostic...
I'll say you here, when i'll receive and replace it. Hope it'll be good.

I am attaching a PDF file with the Service Manual Diagnostic Procedure for the code.

Hello Bill,
Thank's for your answer. Yes i did it, but i knew that P0796 is CBR1/4-5-6 clutch regulator valve (327) in the upper valve body (321)
I ordered an new Upper valve body, because i don't want only to change the valve.
It's a common default to the 6L80 ( Upper valve body), so i wait for that item, and when it'll be change, i'll tell you here.

I spent all my last monday morning to replace the Upper valve body on my automatic transmission.
Unfortunately, it was not that. I had one chance in two to replace the upper valve body or with the control solenoid body. It was not the upper valve body...
So i ordered it, and wait for it on next monday.
Boring to wait...
