a list of the required pieces when switching from AOD to 5 speed mazda or ZF equivalent:
cross member gussets or upper rail supports
link bar for manual shift T case to transmission shift mechanism
transmission mount (i am willing to bet they both fit and bolt the same. very minor differences light height)
and most importantly the driveshafts.
the driveshafts are the most important part and i overlooked them. i thought i would be able to use the ones from the AOD for the 5 speed but i was SOL and there was little i could do about it. front shaft from an f150 was perfect but the rear shaft needed a good 2 inches removed from the AOD shaft so i bartered and got mine resized.
as for wiring, snip 2 wires out of the 5 pin plug for the back up lights, and 2 for neutral safety. i chose not to have back up lights so for the other 2 wires just bring them through the firewall directly off the plug on the fender and connect them to the switch on the pedal. it is a "push to be able to start" setup now that easily.
Hey i have a 1988 ford bronco sitting in my garage i just got my liscense and im wanting to put a 5 speed manual transmission in it rather than the stock AOD i pulled my motor and tranny sold my AOD and took my motor down the the block and im rebuilding it at the moment but was wondering what transmission i need that would be easiest to install to my t case and what other parts i would need to swap it properly
