i've been searching all over the place for info on the t5 to t-56 swap but im kinda confused because one person starts talkin about the 93-97 one and than someone elso comes in and talks about the 98up one, so i ended up on square 1.

anyways if we can keep the info just for the 93-97 T56 will be great.

so here it goes i just got a T56 from a 97 camaro 88***miles
only thing missing would be the fork and the slave cylinder


now my questions.

-For what i understood i will need a center force flywheel p/n 700107
does it HAS to be this specific one?


-what clutch would be a better choice

-the guy i bought it from mention something that kept turning around my head, "its an obd2 transmission" so does this matter??

-how about the vss?

-and will the t-5's mounting bracket work on this one or not? (i've read yes and no, which one is it.)



THANX FOR THE HELP.

 

• I know of no other flywheel that will fit a 2-pc rear main seal engine on one side, and a T-56 clutch on the other. Which is not the same as saying there isn't one; only, I've never come across one. That's the one I have in mine. There certainly is no stock one like that. However if you have a 1-pc RMS motor, you don't need it; the stock T-56 one works.
• I have the Centerforce Dual Friction, and really like it. Others bash it. Frankly, I've never had a properly installed clutch I didn't like; that includes Ram, B-W, Zoom, Hays, and a handful of others. Never had a Spec. Prep and installation is at least as important as brand.
• Monkey-spank
• Yes that will CERTAINLY be something you'll have to deal with. If your car has a VSS in the trans now, you can do it electronically; if it has a cable, you'll have to have a modified extension housing, because the hole for the VSS won't work with a cable.
• Depends on which "bracket" you're talking about. Torque arm, yes; exhaust hanger, yes; trans mount, yes; crossmember, no.

 

Spec, McLeod and a few other companies offer the LT1 T56 flywheel for 2pc seal motors (including 400 and 454.)

There's nothing about a T56 that is OBD-II. The PCM doesn't have any trouble codes re: the operation or dysfunction of the trans. other than the VSS or CAGS, both of which were present in OBD-I cars.

 

ok, so the t5's crossmember wont work, do i have to use the one from the 97 camaro (i have it) or something else...

and the obd2 dsn't have anything to do with the tranny. got that also.

anything else i should know before i start the swap? or the info on the stiky thread covers everything from this point foward for this specific tranny (lt1)

 

If you don't have the pressure plate bolts, researching those would be good. (usually, you can get grade 8 or higher 3/8-16" bolts that are half-threaded shank that work instead of chasing down the GM bolts.)

You'll need a VSS buffer box of some sort (Dakota SGI-5 works) to rcv VSS signal and output to the ECM / speedo. (the T56 reluctor is 17t / output rotation. The T5 is a 4000 pulse / mile. Different...)

The 93-97 F Valeo pull clutch has the disc hub FORWARD into the flywheel bolts, not BACK to the trans.

If it is for sure a 94-97 T56 and your rear is 3.23 or lower, plan on changing to 3.42, 3.73 or 3.90 for drivability reasons.

Everything else is cake since it's a T5 car.

 

GREAT! thanx, i was gonna swap a 3.23 possi, but now you got me thinking... what drivability issues would i have if i use the 3.23?

 

You have to slip the clutch more when you're taking off.
Sixth gear is not useful until a higher speed.

 

gotcha, thanx for the heads up.

 

Slipping clutch....BAD
3.73's.....GOOD
That clutch is the worst thing GM designed, that's why they got rid of it in the '98-up.

When you see one you will know....it pulls instead of pushing.

 

so its better to do the swap with an ls1 t56 than the one i got??

do they make 3.73 gears for a 10 bolt or i need to get a 12 bolt like the one you have Don? if so what are my options.

 

It was a Valeo design used in a lot more cars than just Vettes & F-bodies.

It has more reliable clutch release than the LS1 push hydraulics.
It's actually a perfectly valid design with good surface area.

I'm not a hater.

 

that's what was in 83-86 L69 HO 305 F-bodies and 85-88 SS Montes as well as a bunch of S10 trucks.

Your T56 question is broad. The LT1 clutch gives you more disc surface area than the T5 clutch. If you used an adapter plate with the LS1 trans. and your stock bellhousing, you'd have to shorten your driveshaft and the shifter would be further back.

 

It might have some good features but mostly bad, life is short, ask anyone that has one with power. Also Valeo has the patent so check the price.

I use the McLeod 10.95 push style, same area much better unit.

The bad thing with that 6 spd. and the LS is 1st gear is 2.66 and 6th is 50% OD

I have the other model (aftermarket) 2.97 1st gear and 40% OD in 6th.
With 3.73's I cruise at 2k in 6th. (also '93 trans same gear set)

3.73's are available for 10 bolts (Richmond Gear)

 

i was ready to buy the centerforce flywheel but i notice that the ending year application is 85, im doing the swap on a 91, but the engine is a 350 from a 92 z28, does this means i can use the stock flywheel for a lt1 car?

 

Since you haven't been reading the answers thus far, allow me to quote myself from THE FIRST post in reply.

 

oh i did read it, im just confused, guess i should off asked how do i know if i have a 1 or 2 rms?
i was going through the threads and some say pre 85 but then i see people doing the swap on an 87,88 and talk about using the centerforce so i got kinda confused.

 

hope this help you help me identify it., this is the only pic i have of the rear on the block that will be paired to the t56

 

That's an 86-up engine and will take the stock LT1 flywheel.

One more thing: Bigger stock style starters don't fit in the LT1 bellhousing (a stock L98 starter doesn't fit.) LB9 starters do fit.

 

SWEEET!

how about the starter from an LO3< the car is a 91 rs tbi L03 t5 but im swaping the engine to this 350

 

Should be fine.
