Has anyone done this swap? Is it possible? If it is, I am doing it.

 

Anyone? will it need a dfferent mount? Was that tranny ever a good performer?

 

its just a super t10 with a powerglide

Its pretty strong, they were used on the turbo callaway cars, with some mods to the od unit. The problem is people never maintained them and they fail. Other common problems is on the gear switches so the ecm doesnt know when to engage the overdrive.

Of course the obvious solution is to bypass all that and setup the OD on a manual switch, early c4's 84/85 maybe? have an on off switch on the shifter which is perfect, later models have a mommentary push button that "request" od from the ecm.

You would need the bellhousing and related clutch assembly from an 82 t10 car, the corvette doesnt use a crossmember, it has a torque arm like c-beam made from thick aluminum to bolt the rear end to the tranny. Think how the camaros torque arm mounts to the rear end. The vette beam is similar on both ends.

It would be completley possible to run a set of bolts through the rear of the 4+3 and bolt it to the crossmember. Im not sure if it would line up, or it would need to be moved slightly.

Other problems are the cooler lines for the overdrive unit. If you are converting from an auto it would be easier.

Unless you have an extra one its not worth the hassle. Either you can get them dirt cheap 3-400 or the price is outrageous. I was quoted 1600 for one with 150k miles when i was considering converting my vette from an auto.

Much easier to use the t-10, or t5.

 

Hey thanks for all the info. If I could line it up and bolt it down or get it close and fabricate somethings its worth it. I do have an automatic so that makes me consider it more. Also, its different not just a 700r4 or T-5. Seven gears and a posi rear end with 3.73's would be the shisnitobangsnipsnapitywow:lala:

 

Only 6 gears, and you'd need the 3.73's to get that thing moving at all because the 4+3 weighs a ton.

 

Before you get all worked up over it, go drive one.

It's not seven gears all in a row, like 1-2-3-4-5-6-7; it's a 4-speed, with an overdrive available in gears 2-4. 2 with overdrive, is somewhere between 3rd and 4th; and 3rd with overdrive is a higher gear than 4th. So, your shift pattern ends up something like 1 - 2 - 3 - 2+OD - 4 - 3+OD - 4+OD. Go try shifting it like that.

1st gear is about 2.56:1 IIRC.

All in all, not a very performance-friendly setup. The whole OD thing was a gas mileage thing, not intended for added speed or anything like that.

 

2.64 because it's just a super T10 as far as 1-4 ratios go. I wouldn't mind one but I'd rather drive a T56.

Yeah, it doesn't sound good now that I have had the input I desired. Just thought I would bring something different to the table. Thanks for the opinions. This site rules. I have been waiting patiently for 4 mounths now for the day to come for me to pick up my camaro. Next monday that day comes:lala: Because of this site, I have learned so much and still have so much more to learn. I have read as much as I can about TBI, TPI, Prom burning, cold air induction, suspension, and trannies. I am afraid I will have to start forgeting other things just so I can make more room for third gen info. Every man needs an interest, luckily mine has a large community dedicated to the benifit of said hobby.




Everyone,

Hang out with your **** out

 

The installation is not that difficult if you have basic fabrication skills and lots of time to spend on the project. I spent about a month of evenings and weekends doing it. The installation of the shifter was the biggest time consumer, that and constructing a new crossmember and modifing the torque arm. The computer can be used to control the overdrive unit,it's just a matter of switching a wire or two at the harness connector,and using a corvette prom,and adding a relay to the circuit.
As for the clutch slave cylinder i used a corvette bellhousing and mated it to a stock camaro master cylinder. Ieven reused the aluminum driveshaft from car which was about an inch short. If your going to race the car you might want to add a drive shaft loop just to be safe.

 

how does it run? what kind of rear end do you have. I am really intrigued. Way to go against the grain man. Hows your gas millage? do you race it? I wonder if your the only one yet to do such a swap. It probably wont work for my computer I Have a TBI I think thats a 7747 or somthing. take some picks maybe?

 

I do not have any pictures at the moment. All i have for a camera is a 1 megapixel web cam that takes poor excuses for pictures but if you are interested i can see what they look like. What exactly do you need pictures of? When i did my install way back in 1993 no one manufactured an adjustable torque arm. You could save yourself some work by using one of those listed in the jegs catalge. l can post some repair manual pictures of the corvette stock shifter install sometime later. Im curently running a 4th gen 10 bolt rear with the PBR brakes and 3:54 gears. Gas milage is not too bad if you keep your foot out of the throttle. I never ran the 4+3 at Maple Grove but i ran a 13.80 with the auto.

 

I would just like to see a picture that has a shot of the tranny connected up, and then some hightlights of the custom torque arm and crossmember. Your combo sounds real nice what knd of mill do you have in the car? I haven't even really got the car yet
(only 2 more days) and I have been reading and talking on this board for months. I am determined to build a good camaro Some one offered me a deal on a suburban LO5 I can basicaly pull everything i need of of it for 200, it runs but I would rebuild of course. I like the idea of using the LO5 computer and all and add all the bolt ons for that. aftermarket stuff for the LO5 is easy to find. the holley 670 tbi will work without rewiring a different egr plug(althoughy edlebrock makes a mpfi system just for it too he-he), and not to mention its a 350 roller cam block. The zz9 cam, high silicon pistons and corvette alumnium 58cc heads would go on top. but I am getting ahead of myself first I want to take care of the pegleg rearend stiffin up the shift and make it corner good. Ahh- I want, I want, dont we all want some thing? sorry about the rant its just that I don't have fellow gearhead friends around. I cant freaking wait to get my third-gen RS, dogslow or not.

 

I had a few sites market with pics a while back when I was looking into an OD unit for the malibu then my house got zapped and nearly everything electronic was fried. Seems these are avalible but unless your going to drop a really low (numericly high) gear set in this is not a good setup. It's actually a Doug Nash design adopted by GM strictly for fuel economy, 80's EPA . There was a study after the fact that proved a wide ratio 3 speed transmission would yeild 1/2 MPG better results but it wouldent give you the sports car feeling.

My suggestion would be to go the popular route and drop a T56 setup instead of digging up ancient parts and adapting them to your car. If you really want to be different you could get a gear vender OD unit, a couple of board members have them.
