Asked in Jeep Grand Wagoneer
Why does your 1987 jeep grand wagoneer leak trans fluid from the left side of the trans when its not running?
you may have a bad seal a loose connection or a crack in the case. check the speedometer input.
The transmission cooler lines go into the transmission case on the left side. You probabrly just have a loose fitting. You will have to loosen the fitting on the metal line just slightly and check to see if the fitting it attaches to is loose in the case. If it is, simply tighten it about a quarter turn past snug then retighten the metal line onto that fitting using both wrenches to tighten the fittings together without moving the one in the transmission case.
