94 mazda mx6 automatic trans problem. reverse is good drive is good but 1st gear acts like it is slipping then grabs 2nd does the same hold light starts flashing when this occurs then stops after getting to drive. It seems when i use the hold button it works a little better but the hold light will still flash. Fluid was changed and pan gasket also. Very little soot in pan and no debris. checked fluid flow and cooler all is fine. It seems electrical is the culprit, but i cant find it. I checked all grounds and ohm'ed trans to ground cable.
