(Intermediate clutch)
(Intermediate clutch clearance)
Line 296: Line 296:
 
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.

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.
