1. HYDRAULIC KIT INSTRUCTIONS FOR GM TKO RS T56 MAGNUM AND T45RS BEFORE INSTALLING TRANSMISSION IN CAR YOU MUST CHECK THE HYDRAULIC BEARING CUSHION MEASUREMENT SEE PAGE 8 OF INSTALLATION MANUAL FOR INSTRUCTIONS ON MEASURING HYDRAULIC BEARING CUSHION RECORD THIS MEASUREMENT FOR FUTURE REFERENCE DAMAGE WILL OCCUR IF MEASUREMENT IS INCORRECT MAG 00402 GM Hydraulic Manual Rev B 08 22 14 Silver Sport Transmission The material herein is the intellectual property of Silver Sport Transmissions SST and is to be used by SST customers or their authorized installers for the sole purpose of installing SST supplied transmissions and related parts Under no circumstances shall the manual or any portion thereof be copied duplicated distributed or incorporated in any written or printed document without the express written approval of Silver Sport Transmissions SYSTEM DESCRIPTION This system uses a firewall mounted hydraulic master cylinder with remote reservoir and a combination slave cylinder release bearing assembly This combination bearing is called a concentric slave cylinder CSC and it is designed to be in constant contact with the pressure plate fingers The CSC is compressed by the pressure plate fingers when at rest When the clutch pedal is depressed the master cylinder forces fluid into the CSC causing it to expand and depress the pressure plate fingers thereby releasing the clutch This system works best wi2. prevent brake fluid from contacting paint as damage will likely occur If your vehicle has an over center spring installed it will tend to hold the clutch pedal to the floor until the system is bled enough to return the pedal itself Remove reservoir cap from the reservoir l Fill the reservoir full with DOT 4 brake fluid During the next steps check regularly to make sure that the reservoir does not run out of fluid If this happens you will have to start the process over Open the bleeder screw to allow air to escape from the system Give the fluid a few minutes to make its way down to the bleeder screw while watching the fluid level in the reservoir and refilling as necessary Allow fluid to drip from the bleeder screw into a suitable container It may be necessary to prime the master cylinder by removing the high pressure hose at the master cylinder and block the fitting outlet to draw fluid into the cylinder when stroking the pedal When the cylinder is primed reattach the pressure line and continue the bleeding procedure Take care not to spill brake fluid on any painted surfaces When the drip becomes a steady stream close the bleeder screw Refill the fluid reservoir Open the bleeder screw slightly and have your helper depress the pedal slowly Close the bleeder as soon as the pedal reaches the floor Then have your helper slowly release the pedal Pressing or releasing the pedal too quickly will cause brake fluid to squirt from the t
