Coan built this transmission new for you?
It would help to know what valve body design is on the trans.
Is it a "clean neutral" design trans brake ? You will have a 2nd neutral after 3rd gear. Shift pattern is P N/R 1 2 3 N
Regular trans brake shift pattern will be P R N 1 2 3
Are the stiffer return springs still in the direct drum?
Is there a bleed off hole in the direct drum? Aprox .055 diameter hole
