I have a 94 gt conv. automatic with about 87,000 miles on it. My automatic transmission feels stiff when i shift it into drive when its cold out. Now it did this last winter ocassionaly, but now its been doing it every time i start my car. I can get around it by putting it into Nuetral for a few seconds, then into drive and it will shift fine for the rest of the day. When i say it feels stiff going into gear, i mean that the shifter doesnt want to move. Im going to put in some new tranny fluid and see if that gets me through the winter. Im planning on putting a built up aode this spring, and i want to know if only the 94-95 transmissions will work or if any of the fox's will work. I also heard that the 3.8L auto tranny will bolt up to a 5.0 block. If anyone can help me out, let me know, thanks.
