Please educate me on 3 speed trans RAT & RAN? - Mill Knob - 01-09-2011
I know the differents in RAT & RAT 3 speed trans is their adapter housing.
My Bronco is in need of a new clutch and flywheel. I bought a 3 speed RAT trans a year ago that seems to be better then the 3 speed that is in my bronco now.
The tansmisson in my Bronco is not the original 3 speed, because the Original locked up on the PO and he just slap an old 3 speed transmisson in it and kept driving it. The 3 speed that is in my bronco now is a RAN. Would any body know what 3 speed trans was suppose to come in my 1969 Bronco?
One thing that I did notice was the RAN transin my bronco has a drain plug in the bottom and the RAT don't. :popc1:

Found out by a Chart on the internet that my bronco has in it a 3 speed from a 1967-68 bronco that had 289. The 3 speed trans that I want to put in it can't find on the chart. So still looking.
Tks Jdown67 for the info. Question for you Jdown67 does your trans have a drain plug on the bottom? The Rat trans that I have does not. So how do you change the fluids in it?

I have a RAT (I think) here with a drain plug in it. I am getting ready to take it to the scrapper, unless you need it. It came from a 69. IIRC, the RAT has a lower first gear ratio than the later RAN. Not much lower, but just a little. Kinda like the ratio differences for low range between a T-shift and J-shift T-case.

I'll look about the drain plug when I get home today Mill Knob. I just looked and on broncograveyard site it shows the RAN as having a case length of 9-3/8" and the RAT with a case length of 9-3/4". I never noticed this before.

I know a guy that is restoring a 1969 ford bronco. So I call him up and went over and look at the trans and it has a RAT in it. So that means I am going to place a RAT trans in mine.
