Has anybody done a 6 speed manual swap on a 2nd gen Firebird? My GTO is pretty much done and we're wrapping up construction on a house, so it's about time for a new project and I'm jonesing for a TA.

Is there any major surgery required?

You don't mention whether or not you currently have a 4 speed or auto or what year your TA is or what 6 speed you intend to use. The trans tunnels are different and may require some surgery (installing a 4 spd hump) depending on which trans you intend to use.

I don't presently have a TA, but would like to buy one. If I do, I'd like to go w/ an LS and a manual overdrive trans. Ideally, I'd buy a car w/ a 4 speed or at least prepped for one. If I buy one, I really want a T-top car, so probably 76-81, but my desire is a 77-78. I have the skills to install a hump for the shifter if needed, but really don't want to get into major floor pan surgery (ie creating a custom trans tunnel).

Scarebird here is doing a LS/6spd 79 TA conversion got pics and story at transamcountry 79 Trans Am LS1 / 6sp swap *Spectra fuel injection tank*

I just installed a Kessler ss 700 5 spd in my 73 ta still under construction. I had to install a hump because it was born auto but no other cutting involved. Nice trans. Can't speak for 6 spd though sorry.

I put a Tremec 5spd in my 78 TA 4 years ago from Kiessler ,now I'm putting in a LS / 6spd in my 79 Camaro

Thinkin about dropping the 4 speed and going with the kiesler TKO 600 in my 78 as we speak.

do the Tremec the first time you shift a gear you'll know ,that you have made the right decision

We've built two 73's with LSX engines, one recieved a production T56, the other a Magnum T56, and although close, neither required any floor massaging. The magnum has multiple shifter mounting points, and the handle went through the factory 4 speed hole. It also has a both an electrical and mechanical speedo output. The F-body T56 was modded with a Ford Cobra output shaft and housing which located the shifter farther forward, and also put it in the perfect location. It had to be modified to accept the mechanical cable. All future versions we build will get the Magnum. Link to 455" LSX/Magnum T56 is here:

i did the tko3550 back in i think it was 98 and have never regretted it once i drove the car
sure, it did cost $$
but when you factor in all new stuff and you can drive the car anywhere.... soooooooooo worth it
i just LOVE the steep first gear

I saw that blue '71 at speed inc this summer. Nice car! Went with my friend to fill a nitrous bottle.

I've done a few T56 swaps in 2nd gens behind Poncho motors. It is the most expensive, but it is the best.
