T5 to T56 Swap -need help please
Hi everyone, I mostly read on here since I don't have enough knowledge to give good advise yet.
I gave a mechanic a Harley (worth about $2k) in trade for a T56 and installation back in July... T56 is in, stage 3 T56 clutch is in, but no wiring or hydraulics are done.
Car is a 1991 z28 with late model crate 350
First Question: There are two electrical connectors on the tranny -one in the middle and one at the end towards the rear of the car. There is only one wire coming from the car -which one does it go to? I assume this is the neutral switch?
Second Question: I have the stock T5 hydro setup on the car. What will I need to hook up the T56?
I think I will need to use steel braided line from master to slave?
Will I be able to use the T5 slave?
Will I be able to use the T5 master or should I get a cavalier master?

Re: T5 to T56 Swap -need help please
Depending on the year T56 you should have 3 plugs on the trans.
There is the VSS which is the lowest and near the back(3). The second is the reverse lockout solenoid. This should be right above the VSS towards the back(2). The 3rd if it is a 94-97 trans is the CAGS solenoid (red arrow on image). If it is a 93 T56 it will not have the CAGS solenoid. If you have the CAGS solenoid you can simply leave it unplugged.
Also you can leave the reverse lockout solenoid unplugged it will just be hard to get into the reverse gate. Some people wire it to the brake pedal or have a release switch they press to get into reverse. Some people use a Samoco box to have it work like the factory did it
http://www.samocoind.com/T56MODULE.html
And lastly the VSS for the speedo you will need a dakota digital SGI-5. Since you have a 91 Z28 you should have an electronic speedo instead of the cable driven speedo that the earlier camaros had. The T56 VSS runs at a different speed than the T5 VSS so you need the dakota digital box to convert it.
Hope that helps..
EDIT: Forgot about the hydro question. But yes all you should need is the longer T56 braided cable to connect the master and slave. You should be able to use the T5 master and slave.

Re: T5 to T56 Swap -need help please
Great thanks, that does help, thank you!
I will wire the lockout to my brake lights... seems to make the most sense
For speedo correction i will try to get a dakota digital box
Was a little nervous about the hydro stuff. It seems that everything I read says to grab the hydro setup from the gen 4. Since I don't have the gen 4 hydro setup knowing that I can just add a steel braided line is very good news.

There's no magic bullet to make sure your hydraulics will work unless you make them adjustable. There is a good chance they will work fine, but no guarantee. There's a lot of variance here from car to car.

Re: T5 to T56 Swap -need help please
I did see that article and thats why I got a little nervous.
I think my clutch will be easier to manage/ adjust. Its a stage 3 ceramic so there is no slippage -either its engaged or its not. Lots of grab
thanks again for the reply, I now have a plan of action in my head
1) Remove T5 hard Hydro line from master
2) Replace with Braided line
3) Wire in lockout
4) Wire in Speedo (Dakota)

You will have too much throw. I have a Cavalier slave I'm going to try next and hope it fixes my problem. If you run the t5 pedals and hydros with a SS line it will push the clutch for way too far. Try a Cavalier slave....
Search my old threads as well and you will find the part numbers for the line. Very easy to make...

Re: T5 to T56 Swap -need help please
Yeah I forgot to mention you will have too much throw. You will either have to mod the pedal for less throw or as mentioned use a cavalier slave.
But the 3rd gen hydros will work in a pinch it will just grab very high and possibly pushing the clutch all the way in will make the clutch fork contact the pressure plate.

Re: T5 to T56 Swap -need help please
I looked at all the threads -spent a couple hours reading -its better than a couple hours of hacking...
I did consider the cavalier master -it was the master that changes the throw right?
I really just want to get the car driving first. Then I can decide if I need to get a cavalier master or fab up some type of adjuster.
That sound good? Open to suggestions
thanks for the replies. they are going to save me a ton of time

Re: T5 to T56 Swap -need help please
The clutch line for a 95 camaro is $90-$160
So I bought this whole kit for $93:http://www.rockauto.com/catalog/rafr...parttype=10290
I also picked up a slave cylinder from a 1990 cavalier for $18: http://www.rockauto.com/catalog/rafr...&parttype=2044
I got the last one at $18
I should have everything I need to get it where it should be

Re: T5 to T56 Swap -need help please
Parts came in, installed the gen4 master and slave. I did an easy mod to the master push rod which shortened it about an inch. I think it will give me perfect throw but the pedal sits closer to the floor. It seems to engage properly but won't know for sure until she is off jack stands
Pushrod removed, a little grinding to take apart the pushrod
Modifying the pushrod; simply drill out the eyelit end
Left: a push rod in stock position, Right push rod modified
Now to sort the electrical... this thread & LilSki -your post has been a life saver, thank you. Ordering a dakota as well as a somoco
I decided on the somoco rather than using the brakes because I can see downshifting with the brakes grinding the gears

It allows the reverse lockout to work like the factory where it reads the VSS and allows it to go into reverse when it under 5 MPH.

Somoco is for the reverse lockout solenoid. I changed my mind, I' going to put a lockout switch on the shifter

Re: T5 to T56 Swap -need help please
Mine has about half the throw distance of the brake pedal. Im running a stage 3 clutch so I only needed an inch of throw for operation. I have about 1.5inches to get to the floor after the clutch is disengaged. That's not much at all but at least my clutch isn't hitting. Also I'm using the gen4 flywheel, master, slave, and gen3 pedals

Re: T5 to T56 Swap -need help please
I simply used the 4th gen slave cylinder assembly and it bolted right in using the OEM T5 pedals. I think I had to modify something on the mounting tab on the pedal but it only took about 10 min. Nothing hard. I left the CAGS unplugged, used a SGI 5 box and the reverse lights harness was a simple swap of two wires on the new harness.
The T56 swap was one of the easiest mods I did to my car.
