Hello fellow members, I have just recently installed a Transgo shift kit I my 2004 Ford ranger fx4 4x4 Level 2, . while installing it , the instructions state that in later models the EPC relief valve was removed. , and it states that if there is hole there , I should install a epc valve and spring. the kit didn't come with one. so I just left it and completed the job without it. any information would be appreciated. thanks in advance. Sincerely Paul...
