I pulled the motor and trans out of this 95 gt and put a different block in with good piston rings. In the process I managed to drop about half of the trans fluid. I tried to ad more through the speedo gear opening, but it seems to be well seated and I would really rather not break anything else. I'm looking for an alternate place to add fluid, possible a freeze plug? Is there some special way to remove the speedo gear? I removed the retaining clip, the odometer cable and the electrical connnector, but it is still well attached. What did I miss?
