Hard to find or Possibly Doesnt Exist

[carkrazy1987]

i have a th350c (lockup th350) and i want to put a full manual valve body in it. i dont use the lockup option on it. ive looked around and i cant find anything. im wondering if any of you guys would know were i could find one, or possibly instructions on modify the existing valve body to make it full manual.

im already too deep into this transmission to just junk it and go with a regular th350. so any info would be greatly apreciated.

Thank You
