...Yes! It's the little 'cubic' shaped box on the rear of the transaxle, drivers' side! And since we are talking about THAT box; lay on your back under the Pantera and look UP at the underside of that box. You will find 2 rubber plugs; remove them by gently prying them out. Up Inside each hole is a set screw! I found these loose, once when trying to find a similar shifting problem. You'll need a metric 'Allen' wrench to tighten them. You have to use the wrench length-wise with an adjustable wrench to torque on the shorter end(unless you have a long 'T' handle allen). This may or MAY NOT help you. But in MY case there was quit a bit of slack to tighten up.
