No. An end clutch is a clutch pack on the end of the transmission that is accessible from the outside of the tranny while it is still in the car. It has at least 6 circular disks (3 or more fiber with inner teeth and 3 or more metal ones with outer teeth) that alternate fiber, metal, fiber, etc. These disks fit in a bore where the outer teeth mesh against the sides of the bore and the inner teeth slide over the shaft. The disks have a spring loaded piston that forces the disks together to engage the pack. I do not, however, remember if it's spring applied and hydraulically disengaged or vice-versa.

Hopefully that clarifies it. It's used for engaging the overdrive. Usually they get too warm or worn and warp. One of the symptoms that we encountered was, if we nailed the gas and it down shifted to 3rd and then when it went to shift back into overdrive, it felt like it slipped into neutral until you let off the gas and then it would catch and everything would be fine.
