A4's are inherently harder to shift than most transmissions. However, they're not that hard. As previously mentioned, you should disconnect the shifter cable from the shift lever on the side of the transmission and see what it feels like. Is the cable still hard to move? Is the transmission lever hard to move? If it's fairly easy to shift using the lever, the problem is in the cable. If it's still difficult and the cable moves freely, it's in the transmission (more accurately, reversing gear). I suspect your problem is in the cable. It would only be hard to shift both ways if the unit is "overadjusted" both ways. In other words, if both the forward adjustment and reverse adjustment are too tight. If it's in the transmission, it's reasonably easy to adjust. This is really a very simple unit to work on. I'd recommend you go to the Moyer Marine site which is dedicated to the A4 (google Moyer Marine). The forum there is a wealth of info just on the A4.
