i was wondering which check plug is the correct one to check the trans level i know there's one on the front side of the trans and also one near the passenger side halfshaft... also what are the procedures for checking and filling the trans... i've heard you need to check it with the car running... i have an 02 cav 2200 with the 4 spd trans.... and its got 139K and started to slips going into any gear... bought used and dont want to flush since i dont know the maintainence history..... thanks
