I will admit, we are missing details of the donor truck. Lets not forget the Envoy came with a 4.2L I6 standard, and 5.3L V8 as a option. And the Saab came with the same engines that the Envoy came with, Standard 4.2L I6, and the optional 5.3L V8. The only difference is that some Saabs also came with the 6.0 V8, and no Envoy came with the 6.0.I concur with @NickTransmissions
Your Saab is probably identical (?) to the full-sized 4L60e because it is mated to an LS. That's not the case on the regular Envoys and Trailblazers. The difference are the input shaft 298 mm vs 300 mm, and as was noted, the Atlas bellhousing bolt pattern, and who knows what else internally. Externally they may look the same though.
The bell housing makes no difference, as it externally bolts on, and is easy to remove, and replace. Done it before.
If you are too high and mighty to admit you -may- be wrong here.. thats on you. I will say you might be right. There are just to many variables that we dont know.So...How many 2000-2013 4L60Es have you rebuilt over the years??
You left this question completely unanswered.
Your Saab is in the minority and has a completely different engine belonging to a completely different engine family! Those units are completely different where it counts (as I mentioned to him in my initial reply, if you bothered to read it). The TSS wasn't integrated on a widespread basis into the V8 Gen3 SBC units until 2007 with the advent of the GMT900 platform.
The only one putting him (and anyone else reading this thread for guidance) is you!
But instead of admitting you may have mis-stated things and amend your post, you want to keep digging.
I'm not perfect and have learned A LOT MORE than I have taught since joining this forum. Additionally, there's been a few times where I've stood corrected and learned something in the process.
Perhaps you can learn to do the same, perhaps not.
Your move...
Please point out anything I have stated that is factually incorrect. You cant, cause it doesnt exist.
You are a transmission tech, and I get that. You have done more transmissions than I ever will, and I get that.
I am speaking from my 28 years as a GM Certified Master Tech background. I am not saying that as a superiority complex, but just to say I have been down this road. Warranty companies saving a buck on a used transmission that doesnt come with the right setup for the truck its going in, installing it only to find out its wrong, cause its not easy to see its not right externally.
All I am saying is I have been down the road on a 2005, getting the wrong tranny, and finding out its wrong. It sucks. It sucks bad.
What would make this easy is just finding out if he has a TSS. If he doesnt have one, than all this doesnt matter. If he has one, than we could be saving him time, and money.
I dont want him to have that issue.
