This is just an FYI for the C6 owners. If you get a bunch of miles on your C6, you might get oil seepage from the Skip Shift Solenoid on the manual transmission as what has been happening to mine for a short while. Denoted by a small spot(s) on the garage floor. The internal seals of the solenoid itself began to seep, therefore drip onto the exhaust and finally the floor. Oil dripping onto the exhaust is a bad thing in every possible way imaginable. Replacement is a pain in the posterior. I did find a way, which I accomplished this morning. The OEM sensor requires a special socket of 1-5/16 diameter or in my case, a crows foot open end tool. I had a 33mm socket for drive shaft nuts but it does not fit. Maybe a 34mm? Using the crows foot with a wobbler adapter and long extension, I was then able to get it loose, then spin it off by hand. The new AC Delco sensor to replace it, is a different part number, GM 19210002 and its a different size! I found that a deep 27mm in 1/2 drive socket, fit perfectly, spin it on by hand and using a breaker bar, I could get it up in there and tighten it. No way to get a torque wrench in there for the required 40nm or 29.3FtLbs. but I estimated and job is done. I did not have to remove the exhaust, crossmember or anything else to do this job.

What a pain to have to replace something most of us defeat anyway!

I have tried three different 27mm deep sockets and none of them has socket well deep enough to accommodate solenoid P/N 19210002. What brand of deep socket did you use?

Maney take the 13mm bolt out mand pull the whole unit out. Im not 100% sure but u might have to lower the frame a hair or put ur hands in nigorent to shrink them.

Found 1-1/16 in. impact socket from Lowe's that had enough bite for the job. Used combination of few swivel extensions and ratchets to get the job done without removing any other parts.

I did ur way but some do it the other way when they can't get the one piece out its a two piece set up. But good job tight place. When ever i take a trans out i always put a new one in. Dont care.
