this truck slammed to hard from 1-2 that my dash rattled loose! The builder wont tell me what he did.
when i removed the housing for the accumulator and removed the piston there was no spring in the housing ,

its funny ,but these auto trans are actually quiet easy to work on. i dont wanna do it again though lol
1.Yes there should be at least one spring in the 1-2 accumulator housing. On most factory units there will be two and in some TG kits you will actually have a spring above and below the acc piston. In your case you say there was not a spring at all. Was the piston travel blocked or was it just allowed full range of motion?

2.the larger check ball was probably used because your original separator plate had a factory ball beat itself through it. The hole was larger because of this and what some shops will do is install a larger torlon ball to correct this issue. IMO just install a new plate with 1/4" torlon balls and be done with it.

The obvious issue here is the 1-2 shift.

1. I would look to make sure that the 1-2 feed hole is drilled .082-.093.

2. Check the 1-2 accumulator valve and sleeve and make sure it is not installed upside down. This will also produce a harsh 3-4 shift.

3. Return the 1-2 accumulator to the factory setup.

4. if your trans has a billet 2nd gear servo from superior install a vet servo.

5. Look to see what the transmission line pressure is set at. Minimum should be 75-90psi. Max 210-230 psi.

6. If you have a tune that the transmission line pressure has been altered set it back to the factory settings. If the shift kit has a pressure regulator spring to increase line pressure and also a tune was done this is an issue.

I hope this info helps you some. Vince
