I have my engine out of my '09 HHR SS. It has the stock automatic transmission (4T45-E). While making the engine repairs, I'd like to spend a little $$ and replace a couple things on the front of the transmission. I already purchase the torque converter seal. However, I also want to replace the circled item in the following image. I'm told it's the "turbine shaft o-ring seal."


However, not the dealership, nor several online resources can tell me if it's #40 or #41 in the following parts diagram. From poking around Google Images looking at both part numbers, I believe it's #41, but I cannot find #40 on the front of my transmission (unless it's hidden inside), so process of elimination doesn't conclude anything for me. Can anyone confirm what o-ring I have circled in the above picture?


Thanks in advance!

Just buy both. Use the one you need.

 

Since we cannot see a gear and chain attached to the shaft can we assume you removed it? If so it is pretty obvious it is # 40.

#41 is on the other end of the shaft inside the seal/bearing #42/#43. The torque converter side of the housing.

But if we are looking from the torque converter side.....it is #41

That's what my lying eyes see.

 

The pic of my trans is from the outside, with only the torque converter slid off and set aside. Nothing else has been removed or tampered with.

 

Where's the part # description list ?
#41 looks like the part. #40 looks more like a washer or lock tab. The description might tell you something.

 

This here is the only listing I could find. However, in the numerical listing below its image, it stops short of calling out 040 or 041 explicitly. I'm suspicious that two of the items very near the end of the web page are 040 and 041, but like I said, neither are explicitly called out. So I'm unsure.

 

 

If you follow the line from center of the torque converter it is #41. #40 maybe internal. By the picture you showed I don't see it on the input shaft of the unit.

 

I was thinking #41 too. I found a cheap one at RockAuto (genuine OEM) and threw it in my shopping cart w/other parts. So I guess I'll know for sure when it arrives.

Thanks folks!

 

#41 is the red seal. Right after on the input shaft is #40
