Adding Manual Tranny Fluid.....Help

I have a 1992 MX-3 and cannot find the plug for checking the manual tranny fluid level and adding fluid ..... I drianed the old fluid to change a half axel but the refill/level check plug is not where chilton's says it should be and the speedometer cabel connection is too low...... anybody got any ideas (or pictures)?

Thanks, Mike

I used the front big bolt on the tranny a few inches to the left of the oilpan on the front of the tranny... Use a flewable funnel and I think it is about 3L that the tranny takes.. not sure about the amount tho
