Default can i put a t56 from a 06 gto into a 94 z28?

i have a 94 z28 with a rebuilt 4l60e, it has a shift kit and torque converter, and im still not happy, so i started looking at a t56, then i found 1 from a 06 gto, so will it fit?? and what is better a t5 or t56, i like 5 speed better but everyone insists on the 6 speed. so everyone's input will be considered. thanx.

also ima put all of this into a 89 camaro, i like 3rd gen. better. but before i pay 2 put everything into the 89, i want to know what should i do with the tranny. so i dont have to pay more to do the conversion.

the t-56 out of the gto will be different. the input shaft in a different length then that from the 93-97 styles. theres another difference i forget what.

also to put it into the 3rd gen with the lt1 you need a new crossmember, and i think you have to mess with the engine mounts. also theres the wiring, so on and so forth

The GTO T56 will not work. Find a 94-97 T56 from a fbody. The 93's are rated for lower HP.

Use the six speed. T5's are weak, T56's hold up to a good amount of power. As stated shop around and find a t56 from 94-97.

If you can make the t56 work on the 3rd gen, do it!

T56's are STRONG transmissions and the 6th is also amazing for gas mileage unlike my A4

I generally don't like 3rd gen's as much as 4th gens.. unless if you have a beautiful IROC-Z..

GTO would be nice also for comfort, practicality..

Only 5 speed worth putting in is a TKO 500, TKO 600, TKO 600RR rated at 650hp
The world class T-5 is rated only for 265hp

Yea, the GTO one will be more work than it's worth to change around. That and the Gear Ratios are a little wider than a normal T56. Find you a LT1 one.

You need the offset shift lever from an f-body trans., the front case/adapter plate from a 94-97 F-body trans., And a 1993 F-body input shaft for a 2.97 first gear box. When you do the input / adapter plate, you'll want to verify / correct bearing pre-load. That's it. Don't worry about the lower tq. rating of the MN12 / 1993 F boxes.

And you really should have posted this in the manual trans. forum.

Well in a race you don't really want to get into 5th anyway, that's overdrive. 6th is double overdrive. The point of the t56 is the fact that they hold a good power and can net you some really good gas mileage.

I really not sure what you mean by a lot of people have issues? My car now has 170k on it, I've changed the trans fluid once, I DRIVE this car HARD. Never had a issue with the trans itself. LT1 T56 with all the goodies should cost you $1200 max, a TKO trans is more expensive. The lowest rated TKO starts at $2k and that is just for the trans, its not coming with everything you would need.

There is a Lt1 t56 swap kit in the market place supposed to be everything to swap for 1200 before shipping I believe its worth looking into. I was checking it out but its just not in my budget right now.
