HighPerformaneTrucks.com's beloved time attack Syclone pickup truck's 4l80E built automatic transmission failed during the 2nd practice session at the Reno SCCA Time Trials recently. Both the 700R4 and 4l80E auto transmissions have proven themselves unreliable and unorthodox for road racing so we have embarked on the conversion to a proper gear box in the form of a fully built Tremec/Rockland Standard Gear T-56 Transzilla Magnum manual transmission while retaining the all-wheel-drivetrain. This involves some tricky gene splicing involving a corvette transaxle adapter, custom transfer case adapter, bellhousing adapter, custom 32 spline output shaft as well as custom billet 32 spline internal upgrades to the Borg Warner 4472 transfer case to match the output shaft of the manual transmission.


We started working on the Tilton pedal box. There isn't enough room to weld in the brackets so we fabbed up this custom clamp on bracket. It is adjustable and will not slip. Another bracket is being fabbed up to further support the pedal box. Since the master cylinders are interchangable among brands we will be re-using them from a cost savings standpoint. The pedal position is optimized for heel and toe braking.

George at Rockland Standard Gear is currently building me a Tranzilla Magnum to hold 850 ft lbs tq and will use a 32 spline output shaft.

Transfer case has been rebuilt using billet internals including a billet 32 spline input shaft.

A McLoed twin plate clutch and lightweight flywheel will be used in conjunction with a Quicktime spun steel lightweight SFI bell housing.

I've been patiently waiting for you to post some more about this. Can't wait to see the rest of it.
Have you decided on a shifter and location?

Re: Tranzilla Magnum 6 Speed AWD Build Thread

Once we get the tranny mocked up then we'll address shifter location. Probably won't go with a short shifter, but may need to go with an offset shifter of some sort as we will only have one place on the transmission for the shifter because of the Corvette transaxle adapter in place of the standard 2WD tailshaft.

Just a personal opinion, but this is the sickest thread I've seen on this forum. ;)

I was actually two buildings away from McLeod's offices in Placentia, CA last week.

Looking great Adam!

Image of Junior holding the new Momo suede racing steering wheel with integrated buttons. No the little red buttons won't be called "plaid" or "ludicrous", instead they will be used for turn signals for the time being. Eventually I'll upload some shots of it attached to the Sweet Mfg. quick disconnect on the custom steering "column".

Images showing the complexity of the steering shaft. The Tilton pedal box made a straight shot through the fire wall impossible.

You can see the steering column supports taking shape. A couple more will be added soon.

main.php


main.php


The steering column will be supported by both the safety structure and firewall.

main.php


Some shots of the truck and it's stripped interior pieces.

main.php


The steering column and steering shafts are being designed to be completely bolt in case I need to remove or reposition the steering angle.

What a dream build, and very professional. I can even see the plumb bob hangin' out from the top of the A-Pillar. ;)

This is the adapter ring that keeps the transmission's output shaft properly centered to the transfers case's input shaft. The older style Sy/Ty transfer cases are narrower on the input side compared to later model 4472s.

main.php


Dash temporarily in place to make sure where to place the steering column supports.

main.php


A new bulkhead plate was fitted for new pushlock brake reservoir feed lines coming soon. The clutch master cylinder reservoir will be mounted in the empty space to the right of the brake fluid reservoirs.

main.php


Here's the steering column completed with the quick disconnect splined fitting welded in place.

main.php


Shot of the new MOMO steering wheel with the Sweet Mfg hub in position.

main.php


Another angle showing the completed steering assembly. The wiring really isn't as messy as the images portray.

main.php


Finally able to move onto the transmission mock up stage of the build. Here is a shot of the Bowtie block where the new Quicktime bellhousing and McLeod clutch and flywheel will reside. Notice the Canton remote oil filter sandwich and 12AN lines that run to the oil cooler inside the Ron Davis radiator in the back of the truck.

main.php


Here's a nice shot of an empty space where the new transmission will reside.

main.php


An extra shot of the 3 link suspension and "skinny" tires.

main.php


In this image you can see where the oil cooler lines plumb into the radiator.

main.php


FWIW, here's a shot of the underside of the front of the truck for those who are interested.

main.php


...and another undercarriage shot sans tranny.

Sitting with all four wheels off the ground is a familiar scene for many Syclone owners, I'm sure.

main.php


This is sight of my truck I'm hoping some unlucky Z06 owner will see on the road course eventually.

Maybe I missed it, but how much power is the Sy putting out?

Nice build & good luck racing!
