  • Tranzilla Magnum 6 Speed AWD Build Thread

    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?

            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.





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





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



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