In need of a overdrive unit for my 94 cummins any suggestions on where i could look for one and also curious if in the 94 cummins the tranny is the 47 rh or 47 re?

 

94 and 95 have the 47rh transmissions. What happened to your overdrive unit?

 

My rig out of the blue started leaving a mess all over the ground so i climbed under it to do some investigating and found that one of the top bolts on my overdrive unit was snapped off and another one finger tight and because of it , it allowed enough play in the overdrive unit to crack the case around the lower bolts .. ive been looking online to see if i could track down just an overdrive unit to replace my cracked one but all i have found is one for a 47 re and 48re and also one for a A618 do you know if any of those three are interchangeable with the 47rh ... the A618 in the description said it was for a cummins diesel 4x4 auto tranny hd 96 or older .. Just curious i appreciate any help you can offer
