Sam...
Don't you mean you didn't get to shift to 4th?
What size tires do you have?
2nd gear going around 100mph is a wee bit fast even for 2.73 gears.
Borg-Warner T-5 1983-1987 (V8) 2.95 1.94 1.34 1.00 0.74
BTW - You door plate tells you what rear gears you have. I have the decoder around here somewhere...
What year is it?
