This is a COMPLETE Transmission, No Need to send us a Core T56! Price Includes FREE Shipping!

Introduced to the marketplace in 2012, the Magnum XL is a continuation of the popular Magnum 6-speed series. Featuring all the most important content from the original Magnum, the XL retains its brute strength and sophistication, but eliminates its multiple shifter locations and dual speedo outputs. Refinements include a new extended length tail section designed to eliminate the semi-remote shifter found in many popular late-model applications.Initially available for the 2005 and up “S197” Mustang, we have now swapped the input to allow for use in GM vehicles too. With our Level 4 Magnum XL Conversion, Tick Performance offers you a transmission that will safely support up to 900ft/lbs of torque! Some benefits you'll enjoy over a standard T56 transmission include:

The ability to choose between 2.66 and 2.97 gearsets
Triple-cone synchronizers on 1-4 gears, along with double-cone synchronizers on Fifth, Sixth and Reverse
Wider, two-piece laser beam-welded speed gears which feature built-in positive stops to virtually eliminate the possibility of "overthrown" shifts
Much stronger one-piece countershaft that resists distortion far better than previous designs and uses larger bearings in all critical support areas for increased stability
Input Shaft features additional material throughout the length of the shaft, increased face width, a larger input bearing, and generously long splines to accommodate twin-disc clutch setups
Considerably narrower synchronizers that feature fine-pitch tooth angles to effectively decrease the amount of travel necessary for engagement
Redesigned shift forks featuring integrated "shift keys" to virtually eliminate the possibility of bending shift forks
Added cross-sectional material on shift forks for increased rigidity and larger shift pads to promote better wear characteristics

A Magnum XL WILL NOT bolt directly into your 2004-2007 CTS-V. The following list includes the required items for this to be a direct bolt in.

1998-2002 F-Body Style Clutch
1998-2002 F-body Style Slave #24264182 or a Tilton 6000 Series Slave #60-6105
1998-2002 F-Body Style Bellhousing #1386-212-005 or a Quicktime SFI Certified Bellhousing #RM-8020
A custom 3.5" driveshaft
A custom transmission crossmember or modify your OEM crossmember
Our stainless braided clutch line #TPUSLCTS and Earl's Slave Cylinder Fitting #LS641001ERL
Anchor Transmission Mount #2639

We provide you with a new vehicle speed sensor, reverse lockout solenoid and reverse light switch.

When you place your order, we completely tear down the T56 Magnum and begin our upgrades that we perform in house. Those upgrades include:

Installing Carbon Blocker Rings on first, third and fourth gears (second gear is already carbon)
Upgrading all fork pads from plastic to bronze
End-play set to our custom specifications
Professional Reassembly done 100% by hand
5 Qts of Fluid

Option Guide: Which 1-6 Gear Ratio Set do I need?

It truly depends on how you plan to use the car! The 2.66 Gear Ratio set retains the same 1-4 gears as the Stock LS1 F-Body T56 but has slightly more aggressive overdrive gears. The 2.97 Gear Ratio set retains the same overdrive gears as the Stock LS1 F-Body T56 but has slightly more aggressive 1-4 gears. If traction is something you're constantly trying to find, the 2.66 Gear Set will be a bit more forgiving.

Option Guide: Should I have the Bungs & Sprayers Installed?
It is seen time and time again in big horsepower cars that do standing mile or high speed pulls often, and road race or autocross applications; the input shaft bearing can become starved for fluid and fail, causing a chain reaction of damage inside the transmission. With this option, we install and weld bungs and spray tubes inside your transmission that will direct transmission fluid onto your input shaft and third gear teeth that are prone to failure. This kit now includes our Hi-Flow Transmission Fluid Pump Kit. This kit will require some plumbing and electrical wiring. This option adds no extra turnaround time.

Option Guide: Should I Upgrade to an Aftermarket Gear Set?
Tick Performance has partnered with PPG to offer the strongest gear sets on the market with our industry leading transmissions. You have the following options for gear sets:

Faceplated 1st-6th
Faceplated 1st-4th (Allows you to retain or delete your 5th & 6th gear)
Synchronized 1st-6th
Synchronized 1st-4th (Allows you to retain your OEM 5th & 6th gear)

Faceplated gear sets are designed for race only applications and not recommended for street use. The faceplated gear sets include the gears, mainshaft, billet shift forks, slider assemblies, and billet interlock & bolts. The synchronized gear sets include only the gears themselves and will reuse the factory synchronizer assemblies, shift forks, mainshaft, and interlock.

The synchronized gear sets are available with the following ratio:

2.437 – 1.611 – 1.228 – 1.000 - .891 - .80.

2.437 – 1.611 – 1.228 – 1.000 - .797 - .634.

The faceplated gear sets are available in the following ratios:
2.148 - 1.561 - 1.228 - 1.000 - .875 - .770
2.437 - 1.611 - 1.228 - 1.000 - .875 - .770
2.589 - 1.841 - 1.352 - 1.000 - .797 - .630
2.946 - 2.071 - 1.438 - 1.000 - .797 - .630

If you are planning to retain your factory 5th & 6th gear the ratio will change as the PPG input ratio is different than OEM. To find your new ratio please use the following formula.

OEM Ratio / 1.161 = Y
Y x 1.381 = New Ratio

Option Guide: Do I want Powdercoating?
This transmission will look brand new when it arrives at you door, but if you're building a show car you may opt for powdercoating, which is much more durable than paint. Available in Black Satin or Silver. This option adds 10-15 days to your turnaround time.
