| Clutch Alignment Tool | ||
| If the transmission is out we recommend inspecting the clutch disc and pressure plate. It is much easer to do it now than find out one or both are bad after you put the transmission back in. If you do the inspection you will need a Clutch Alignment Tool to reinstall the clutch. | ||

This tool (or one like it) must be used when installing any clutch (new or old) to prevent damage to disc, pilot, transmission, and/or the person attempting to put the transmission or engine back in. | |

| We are finding a significant number of broken or sagging mounts that transmit noticeable vibrations into the car. It is only a few more nuts and bolts to install a new mount while the transmission is out. | |||

| The transmission is actually held up and in place by the "Y" blocks listed below. The crossmember is more obviously bad because it's bushing actually breaks, while the "Y" blocks rarely break, they just sag, causing the bushing in the crossmember to break out. If you replace the crossmember, but not the blocks, your new crossmember will soon fail. The bushing in the center of the crossmember is not designed to carry any weight. | |||

| Transmission Front Cover with Seal | |||
| It is always a good idea to replace the front seal on the transmission when replacing a clutch. What we are finding is considerable wear on the transmission front cover from the continual release bearing movement. If worn too much, the pressure plate will fail prematurely from release bearing side movement and misalignment. | |||
