Hey everyone! I really want to upgrade the transmission in my car to an F40 6 speed and wonder if anyone out there has one they would be looking to sell. I appreciate it!

I've been considering doing a 6-speed swap in my 3800SC car and this is what I've been looking at.

Car list for F40: https://en.wikipedia.org/wiki/GM_F40_transmission

Looking at that list there, the easiest thing I can think of for finding these transmissions is the 1.8L Chevy Cruze. I go look on https://www.car-part.com and find a bunch within a few hundred miles.

The F40 from the 2006 - 2007 G6 is the only F40 application with the GM Metric bellhousing. None of the other F40s will bolt to the engines typically found in the Fiero (unless you are swapping in an Ecotec).

Something like 1500 cars only had them in it.
I have a 60v6 f40 waiting for install.

I bought a pallet of 6 many moons ago. They sold really fast when i finally let them go. Now one of my buddies is looking for one...SMH. If you do find any let me know please.

How much do you think a good one is worth?

In another thread fieroguru said like $2500-$3000, which is crazy to me. I might just wait until the community figures out parts to swap in the ecotec F40 . With how rare the G6 F40 is either that's going to happen or these swaps won't be a thing anymore real soon.

Oh that's right, and if I remember, those were all brand new....correct?

Eh, here's on in the UK if you can get the guy to ship. He imported it from the U.S to build a kitcar on his Fiero but never used it. Now he's selling it.
