I have a 92 tracker that had a bad modulator, so I changed it. I drove it and realized something was not correct. I figured out that I didn’t put the plunger back in when I installed the new modulator. Now I can’t get the new modulator off to put the plunger in. I feel like I didn’t tighten it too much when I installed it.  Why would it be so tight? Did I just ruin my transmission?
