I have the same trans, and just replaced it at 80,000 miles, which I dont think it shouldve gone, but Im the 3rd owner so who knows.
Im assuming yours is a 3.0 or you wouldnt be asking about cross reference. How did the cab mounts collapse is what Id like to know. Lets see some pics.
If you dont have a tranny picked out I recommend Kormex Transmission from EBay. They usually have a few Ranger trannies listed, and they are helpful and inexpensive (even with returning the core)
