Thanks in advance,

I was just about to say 10mm but then I realized I also have a 12mm allen wrench and I can't remember which one I used.

Last time I checked it uses a socket drive for the drain and fill plugs. 1/4 or 3/8ths drive.

TTT for ya

3/8" for the tranny drain and fill plugs. There might be some crud build up in the fill plug that needs to be scraped out.

The diff drain and fill plugs take male hex (i.e. allen) sockets, but I can't remember right now (fat lot of help I am, huh!).

BTW, remember to add a bottle of GM limited slip additive to whatever fluid you fill with.

I'll try to remember to go find it tonight when I get home.

HTH, and have a good one,
Mike

Sorry about the delay: I went out and checked, the differential plugs take a 3/8" hex socket. Only about 20 ft-lb on the torque.

HTH, and have a good one,

Default Thanks Folks!

I got the trans, diiff, and oil changed today

I did not realize that there was a sensor in the trans fill plug

Thank you all so very much for your help. Now, I have to get the car started. This is sad, I bought this car three weeks ago and have yet to drive it

Oops, my bad on that one. I forgot you have a Z06; the sensor in the fill plug is a temperature sensor. You won't see it displayed on the DIC unless the temps get to a warning level. Then it's displayed instead of the engine oil temperature.

Glad you got everything done; now go have some fun!

Have a great 4th,
Mike
