TH 350 accumulator spring

[falconvan]

I'm putting a B&M shift kit in a TH 350 that I have. I bought this from a guy who said that it was in a truck he bought and it worked OK but banged the gears so hard that it got on his nerves so he pulled it out. I thought if I just put in a standard B&M shift improver kit it would help it out. Two things; when I pulled it apart I found that the 1-2 accumulator spring was way lighter than a stock spring. Should I switch to the stock one? Also, when I took the valve body off, I found that there was no spring under the 2-3 accumulator piston. I've got two different manuals on these and both show that there should be a spring under the piston. Any ideas? When I pulled it apart it had some other brand of valve body spacer plate in it that I never heard of. Does anyone recall using a kit that might have said to leave the spring out?
