·Can you believe my luck with transmissions?!
Let me tell everyone what I have, then I will ask some questions.
351C C-6(Just rebuilt) TCI 10" converter(3000 stall I think) TCI manual-reverse valve body.
The car seems to shift fine under minimal load. 1st gear is strong, and the shift from 2nd to 3rd is very strong. The problem is with the shift from 1st to 2nd. Under 3/4 to full throttle, slipping occurs. If you briefly let off the gas it will engage, and hammering it again it stays engaged. The shift from 2nd to 3rd is very strong and instant, no slipping. If you have it in 3rd and downshift and a good rpm, so that the rpm's are high in 2nd, it shifts fine, and holds good. It is just slipping from 1st to 2nd under medium to heavy loads.
Now for some questions.
Should the vacuum modulator be hooked up on a manual valve body tranny? (it is not)
What controls the line pressure if the modulator isn't hooked up? I know in a normal valve body, the vacuum controls it. Is it not needed in a manual valve body?
If it is not needed, what should the pressure read when measured? Does it run at full pressure all the time? If so, isn't that bad on the seals?
My tranny guy and myself test drove the car tonight, and the above observations were noted whim him driving the car. He doesn't know much about the manual valve body, and neither do I.
Why is 2nd slipping? He is positive that he did the band adjustment correctly, although we will check this Thursday, along with checking the line pressure with gauge.
Help me out here guys....... Please!!!
