=T-350 Intermediate clutch= 6 cylinder applications use an intermediate piston measuring 1.175"-1.185" thick. The 6 cylinder uses two frictions. The V8 T-350 intermediate uses three frictions. The T-350 piston is about 0.990" thick. The wavy cushion plate should be used. There are two types of intermediate return spring/retainers. With the early type you had to manually place the loose springs onto the piston's spring locator bosses,then the retainer went over that. The later retainer has the springs attached to their respective retainers (the bosses are not used). So if the intermediate piston is smooth, use the retainer with the springs attached to it. The late retainers will work in a transmission that originally used the early type retainer, but not vice versa. ==T-350 Intermediate clutch clearance== After the pump is set into place to test end play clearance, you can also check the clutch clearance on the intermediate clutch pack. Clearance of 0.050" to 0.070" will work well. There are thicker intermediate steel plates available if need to tighten up the clutch pack clearance. T-350 Intermediate steels are available in 0.068", 0.078" and 0.089" thicknesses, some manufacturers may use slightly different thicknesses than these. Also, a T-350 scraped low-reverse friction can be used under the intermediate piston if need be. A scraped T-350 friction will measure about 0.032".
