trans info needed

Count how many friction plates are in the front drum. If it has 3 frictions it's stock and light duty. If it has 4 it's medium duty. If it has 5 it's heavy duty. BTW: You can convert a 3 friction drum to a 4 by using this plates designed for the rear clutch. Just make sure you set the clearance properly. I like to see .050-.065" clearance on a 4 disc drum. You can also convert a 4 disc to a 5 by the same method. Check the rear drum also. They can be a 3 or 4 friction drum. The rear drum is not a shifting clutch so it doesn't necessarily need 5 discs, but it doesn't hurt to have 5. If it's a 3 0r 4 disc drum the only way to add more is either changing out the drum for one that holds more or using a thin pressure plate. Check the ratio of the front band apply lever. A perf. lever is generally a 3.8 or 4.2 ratio and those #'s are stamped right on the side of it. If it's a 5.0 lever swap it out or you may have shift overlap (very detrimental to a trans.). The 5.0 lever was designed for the Hemi trans. that had a wider band that was harder to apply. Use a 3.8 lever if the front band is a flex band. Use 4.2 lever if it's a rigid band. If the accumulator is blocked (spring removed and a blocker rod installed) that's a sign it may have a shift improver kit in it.
