Default T56 in 71

Hello
I have just a quick question for now. I am in the process of doing a frame off on my 71. I have a built LQ9 engine that i will be putting in it and would like to bolt it to a T56 Trans. I have been doing some reading on the many T56's out there. I am trying to locate one that i will not have to buy additional parts ( bell housing, flywheel ect) for. That being said can someone confirm that I need to be looking for a 98-02 Camaro trans? I am pretty sure the later model T56 that are in the Camaros 93-97 will work but with these i would need a conversion bell housing. I am wanting a bolt on pc. Any help would be great. My head spins with all the T56's out there....GTO, MUSTANGS, CAMAROS, CORVETTES ect.

Bolt in, use one from a late model Camaro 98-02 or one from an 04-06 GTO. For the record you can use one from a 93-97 f-body (lt1) but you have to change the mounting plate, input shaft and bell housing. Not hard plenty of YouTube how to.

You cannot use one from any mustang, you can use one from a viper but NOT bolt in. And you cannot use one from any Vette.

nyciti....Thanks so much for the info. This is exactly what I was looking for. I am aware of the changes you can make to the 93-97 but with the price of these T56's these days I am just going to look for a low mileage one I can bolt right in. Thanks Again!

Np - you can also always buy a magnuam and not deal with a used, the price point aint much different. Just be advise they are larger than the t56 but still fit.

Every once and awhile rebuilt T56's come up on LS1tech. I struggled with the new versus used and went with a new magnum.

id get an LS1, many trans shops have rebuilts ready to go. Most are getting too old, lot of $ to risk and have to spend another 1500 to rebuild.
450 lb tq rating (they can take more)
If you dont like the stock shiftter the Hurst feels great.

I found one from a 04 GTO. Anything else i need to grab with this trans if i decide to pick it up. It has 67k on it and has a release bearing. Any wiring harnesses?

Mine is from an 06 GTO and works fine. I did install a new TO bearing because it was cheap and I did not know what it had been through in its previous life. The gear box only had 19K miles on it so it was virtually brand new. As far as wiring nothing you need from the GTO. Depending on what you are using for a computer ad wiring harness it will require something. My harness has wires for the speed sensor so the computer knows its speed. Other than that you can wire in your backup lights also into the factory harness. I am using a GPS speedo so nothing there on the trans.

Actually you need the wiring pigtails for the VSS and reverse lights switch. You will need a switch if you don't want to muscle through the reverse lockout, but in the 6+ swaps I've done ive never wired it.

You can make or buy them if not available. You can't use the tranny mount from the gto you will need a new one. I run an mgw f-body shifter but the pro-5.0 is okay too. Other than crossmember and hydraulics you should be good. For the hydraulic / pedal if you going to buy one you can use one from an 81 c-10 (double check the year) or you can make an adapter for a tilton (what I did) - it must be a 15 degree for the proper pedal angle. Last piece of advice get a new slave and a remote bleeder while you have it all apart.

One major thing missing is your driveshaft. I could not find a 27spline 1330 two piece yoke. Its 1310 or 1350. If you go 1350 you will have to cut a hole on the pass side tunnel for clearance. A 1310 will fit no problem. Also check if your rear is a 1330. I cut the tunnel and reglassed it and went 1350

I scooped up this 04 GTO trans a couple weeks back. I am going to start rounding up parts for this but have a few questions.
1. Did you buy just a stock GTO release bearing or something after market?
2. I am bolting this to a LQ9 ls engine. what clutch and pressure plate should i buy. This is a budget build, street use only, should have near 500hp.
3. I have been reading to get a Truck master cylinder from a 85 1/2 ton. does this sound right.
4. what shifter did you use? i am not against modifying it. i have a welder and basic tools. just want to know what you started with.

My car was a original 4speed so i wont need to buy a pedal set up. where did you mount your master cylinder? I plan to mod my existing cross member and make it remove able. Does not look to tricky. Does this get me covered above?

See below....

2. You can pick up an Ls7 clutch kit for under 500 and it will have everything you need. Again nothing more needed and it will hold that 500 all day. Maybe need the flywheel bolts.
3. Yes you can use the truck master, it's dirt cheap and it's what almost everyone uses. However I didn't, I made a bracket for a tilton / wilwood and went that route. If you want to do that it's 15 degrees of angle for proper pedal alignment off the firewall. Took me maybe an hour to Fab. I didnt like the level of cheap that truck one looked to me and I didn't know what the pedal feel would be. I HATE a soft or mushie pedal. I know what the titlon is like, it's completely rebuildable and just works!
4. I have a custom center console so shifter was much less of a concern. However my shifter is an fbody mgw one. I also had the pro5.0 which might be easier to mod.

My master is mounted next to the brake master - I used an body bracket, fluid holder, and lines, perfect length no need for custom. For the cross member I got lazy and got one from bowtie overdrive. I normally would never do this cause welding and fabbing is what I do. However, time vs money and I wanted the weight savings and the insane amount of exhaust room it frees up under the car.

Don't forget about the driveshaft and the ujoint BS.
Hope that helps.

do you have a pn for that truck slave? Thinking of trying that one rather than get another Fbody. Mines leaking from sitting too long
Does it fit the same angle? Bracket is a pain to remove

Here you go - I can't speak for this, I bought it but didn't use it. However a LOT of folks here have, it pretty much falls into the car its dead simple. You will have to cut the rod and thread it down with a coupler as it is too long, I think it was about 1.5 inch but double check that!

Also sorry if I wasn't clear you can NOT use the stock f-body slave it comes in at about 23-25 degrees and our cars need 15. It will NOT work without an adapter. However you can create an adapter to use a Tilton or Wilwood This isn't my car but I literally did the same thing except I made my adapter bracket and I'm using a Tilton. But you get the idea.
