I have plugged the vacuum hose going to my modulater on my 350TH in my drag only car and must shift it manually. My question is, when I stop the car and put the trans in 3rd gear, manually, then drive off slowly, the car seems like it is still in 1st gear, ie- high revs going slow. I thought it would be very sluggish since it was in 3rd gear. I can stop the car, put trans in 1st, drive off slowly and shift it to 2nd then to 3rd, then stop again. Leaving the trans in 3rd, when I start off, it still seems like it is in 1st gear. What do ya'll think ? Is this right?
