Here is a pic of the ford manual 4x4 transmission that I'm trying to id. I'm posting in this section because I don't have a clue where to post. Any help would be much appreciated. I'm hoping its a 5 speed that would handle a 4bt cummins for a new project. I will try to get some numbers up soon. I have researched the hell out of this and can't find anything. The transfer case is a new process 208f.

 

Here's some numbers I found on side of case.

I think I found your answer (Googled it dude):

Read, read, read.

 

Thanks for the link dude. Believe me, I have several times. Seems to be a not so common transmission. Od sounds good, but a comment was made about not so tough. Wonder if a 4bt is too much torque? Will continue to research.. if anyone has ever tried this combo, please let me know your results.

 

Be aware that the RTS TS-OD is a "weak sister." One speed shift, you can kiss the little darlin' good bye.

This trans is a modification of the RUG SR-OD 4 speed, originally designed for Granada's and Fairmonts with I-6's and 302's.

Ford began installing this trans in F100/150 & E150's in 1978 in an effort to improve fuel economy...which became an important issue for the very first time...during the first Arab Oil Embargo that occurred 1973/74.

The second Arab Oil Embargo occurred in 1979. A gallon of regular jumped to a buck from 20-25 cents after the first embargo ended, jumped to a buck 25 after the second ended.

The prices look cheap, don't they. But, they aren't cheap, because back then, a buck was worth far more than it is today.

 

Thanks #dummy. I don't need any weak sisters. Cancel that idea. So probably a small block zf I guess. Already have ford adapter so options are limited.
