Eaton RT12609a to RTX147010c swap

Hi all,

I post here from time to time about my truck (1995 IH 9200 with a CAT 3176b), anyone who remembers me knows I’ve been contemplating some gearing or transmission changes. I got to drive a very similar truck to mine with the same rear end ratio, 3.91, and same factory horsepower rating, 350 and the difference is night and day. Far as I can tell the big difference is the transmission, which is in his a RTX147010c. Just so happens there’s one with 30k miles (with paper work) out of a wrecked truck a little north of me at a good price, has the bell housing and complete shifter too. Since I will need to hunt down parts I have some questions. Is there any complications going from a RT to RTX? Would I need a different flywheel (which also would determine which clutch to but I assume)? Would the drive shaft need its length changed? Clutch linkage going to need reworked?

I guess I just want to know how much screwing around will have to be done to make this much needed change.

Current trans is a RT12609a for reference.

Thanks!

 

Thank you both! I went ahead and picked up the 1470 today, got it for $1k don’t think it did too terrible with how complete it is and with its rebuild paperwork. Hoping to get it into the shop next week sometime after I finish up a contract.
