i dont know much about the corvette transaxle setup. Is it the same transmission as the f bodys? if i locate the right bellhousing and tailshaft can i install one of these in my 85 iroc?

I only ask because i have the opportunity to buy one extremely cheap. Any help is much appreciated as always.

 

The transaxle is only in the '08+ C6 Corvettes & would take a LOT of fabrication to fit. Your talking about replacing the entire rear axle, entire rear suspension AND the transmission.

Hope your fabrication skills are up to that task. Not to mention, the PCM controls of the transmission operation, which would require a lot of tuning programming to figure it out, if it is even possible to do.

 

i think i should have been more clear, my fault.

i am wondering if i disassemble the transaxle, can i just use the t56 transmission ands put an lt1 bellhousing and tailshaft on it and do the standard t56 swap that is covered on this website in great detail.

Or is the corvette t56 different than an f-body. I mean besides the obvious transaxle, is the base transmission usable for my application?

 

how cheap is extremely cheap? if it's the right price, buy it and i'm sure you can use it somehow. what year corvette?

 

I doubt that your gonna find much useful info here, on swapping the guts of a transaxle into a standard case. Doubt your gonna find much info on doing that anywhere, on such a new item.

Good luck!

 

$250, and its a 99 vette. Im thinkin that the cheap initial price is gonna skyrocket when i start adding up the conversion stuff.

 

'99 or '09?

'99 wouldn't have a transaxle, just a standard transmission bolted to the engine.

If its off a '99, just swap the whole transmission in, but you'll hafta get aftermarket torque arm mount.

 

No, all C5s had transaxles. That's anything 97+.

 

yeah, its definatly a transaxle. but i didnt physically see the car so im not positive of the year, im just going by what the guy told me.

 

did you say $250? buy that thing. you could probably make it work somehow. torque arm that mounts to the frame and a custom made transmission crossmember. then it's just a coulple other things, it'd be worth it.

 

You can swap all the internal parts onto a GTO mainshaft ($200), get a LS1 Fbody Bellhousing/mid-plate/tailhousing, (~$700 new) and then you'll have a nice LS1-fbody transmission. The '99 C5 still had paper lined blocker rings, so you should expect another $500 rebuild on it.

This will get you a very nice transmission, but still alot more $ than most folks will want to put out. If you can find a LS1 Fbody T56 with broken internals, it makes the conversion much more cost effective... I've converted a dozen C5 units to Fbodys now.

 

one of the things to consider though is my engine is a 2000 vortec 1 piece rms so i need the LT1 conversion parts. will they bolt to the ls1 t56 transaxle?

 

The C5 input shaft is the same length as the LS1 Fbody T56, so you'll need to further convert/adapt the hybrid to a GenI/GenII motor in the same way as any other LS1 Fbody T56.

I've picked up quite a few $200-$250 C5 units, for the main reason that they are only good for other C5s, or as parts donors.

Probably keep looking for an LT1 T56...

 

yeah, thats kinda what i figured.

Thanks all for the input and helpin me save a couple hundred dollar headache

 

I'm running one of the dozen, and it's the smoothest-shifting transmission I've ever driven. The 3-piece Vette synchros make upshifting very positive and effortless. Great mod!

 

I'm assuming this is the one that was on the Chicago Craigslist? That guy seems to always have different transmissions up for sale and he knows what stuff is worth when it comes to Lt1/LS1 T56's.

 

yeah it was on craigslist chicago.

i have been having great luck with craigslist so far. everypart of my project (except the vortec engine i bought from a member here) has been sourced from craigslist. Its been cheap and so far i havent had an horror stories. I have heard a few though so im sure its just a matter of time.

 

I spent $300 on a junkyard C5 gearbox with a known bad Reverse synchro, just to re-use the guts in my T56 as '85MikeTPI' described above.

He assembles the C5 gears onto a GTO mainshaft, installs it into the F-Body T56 case after doing all the measuring and preload-shim configuration, and you end up with a very smooth shifting gearbox.

 

The OP is looking for a LT1-T56 for a SBC setup. The Hybrid would only work on a LS1 motor swap or with the adaptor plate to mate to a T5 setup.. So while the Hybrid is the bomb, it's NA for this setup.

 

^^ what he said

thanks for all the input though, you guys saved me a headache and good chunk of my budget.

 

Did you talk him down from $600 to $250?

 

no, the original deal is gone.

the 600 dollar one is from an 02 zo6
