I am just curious as to which transmission a '93 runs? I'm toying with the overdrive idea, and theres two guys selling '93 tranny's in the local classifieds at the moment. They both want premium dollar for 'em so i cant see myself owning one, but not knowing what im really contemplating bugs me. are these still a 518 or had they started putting the 47RH in them by then? and if it is still a 518, was it a lock-up unit behind a diesel yet or was that a gas-job thing only before the 47RH?

 

for what i have heard is a 93 is just overdrive with no locking t/c and 94 95 where still hydrolic with lock i think a 93 is a two wire and 94 95 were 3 wire if im wrong any one correct me

 

I have a complete rebuild and troubleshooting electronic manual for these trannys if you'd like me to send it to you. Mine puked o/d so I did a bunch of research before taking it to a shop in Calgary to be rebuild... 1 week and $1800 later its good as new thanks to the guys at AllTrans

 

You got it

And I love my 94 47RH - just be sure it's a diesel 47RH, the gasser ones have different throttle bodies, TC's, and governor weights.
