Hello. I have a 64 Hardtop with a verified and documented 46,000 miles on it. I have had the car about 5 years. I love the car and always get comments and thumbs up when I take it out of the garage. Lately the trans has started acting up. When it is cold, it shifts fine, but when it gets up to normal temp range it starts skipping second gear. It starts out in low[first] and shifts straight into high[third]. Does anyone have any ideas short of rebuilding the trans? I understand it has a modulator located on the outside of the trans that has something to do with shifting. Thanks
