automatic transmission upgrades

hi all,
My dirt track car is running great with the auto.. however, i have no kickdown cable currently hooked up and i just have the lever on the trans that is for kickdown detent cable zippie tied up fully....

running the car 1 click down past drive... it will shift 1-2 1-2 and 2-1 2-1

2 clicks back past d it just starts out in 2...

2 works well on the track putting me at about 6700 rpms in the corner at the end of the flat...

but sometimes depending on the track and how hard i hit a turn it would be nice to hit 1 and have the R's up coming out of the turn and then hit 2

anyone know of anyne putting a manual valve body in a crx tranny...

I worked in a tranny shop for 3 years and honestly have never touched, pulled or worked on a honda tranny. ..

i have done alot of modding to gm trannys but i need some advice here//

thanks
