I swapped a powertrain out of a 2005 GXP into a Pontiac Fiero. During the swap, I partially disassembled the engine and took some pictures. I posted these pictures to the following webpage along with some information...

You can see a write-up of the Fiero swap here:

That thermostat housing doesnt look fun to play with. Also I have a few questions.

1. What is a TCM?
2. Are any of the components/parts etc. on that motor beefed up and transferable to the L67 platform?
3. Is that an engine stand you are using to hold that transmission?

Sorry for all the questions.

Great documentation on the whole thing though, hats off to you for that.

It whines a lot, but I like it.

Even if you shoot for the moon and miss, you still land among the stars.

Scotty those cars use a TCM, Trans Control Module as they are not all one unit as the 3800 cars are/were. The car runs awesome and I think I know who worked on the trans I will let Ryan finish the rest of your questions

Ive been on the look out for one around here in fact as a project car. I owned one several years ago, but it was the 2M4. I enjoyed it nonetheless though. It was a fun car to drive.

Thanks for the props.

1) AFAIK, starting in 2005 GM went to splitting up the transmission computer from the engine computer instead of having it in one unit. In some applications, the transmission control module is actually located inside the transmission.

2) The LS4 is completely different from the 3800. I don't think there is anything on it that could be used on the 3800.

3) Yes that is an engine stand I used to hold the transmission. Works quite well.
