5 spd help
i have an 89 f250 4x2 with a 351w 5spd that i got recently and i am wanting to put it in my 78 f250 crewcab 4x4, is this the zf 5 spd or is it different? if it is different is it as good? is it hard to mate the 2wd tranny to my np205? the 78 had a 300 i6 and np435/np205. I was given the 89 it has 100,000 miles on it i was allready planning on putting a 351w and 5 spd in the 78 so this came along at a perfect time but i don't know if the tranny is worth swapping in and what will be involved hooking it to my 205. thanks in advance.

The 4x2 trans will need to have a new output shaft designed for a 4x4 set up so mating it to a 205 is very costly because one needs to buy a new output shaft and install it plus buy the rear t-case adapter. IMO not worth the effort unless you had a 4x4 trans that was bad and needed parts from the 4x2 trans.
With out seeing the trans of the vin identification you could have either the Mazda or the ZF trans and the Mazada is not nearly as strong as the ZF.
The 205 will ount to the ZF and the Mazada as they all share the same t-case bolt pattern. On the ZF you will have to notch the t-case adapter to clear the 205 shifting lever and the rod from the shifter handle to the 205 shifter lever will have to be shortened. I just mounted a 205 to a ZF so this I know first hand but i am a few months away from getting the hyd clutch set completed.
I will be documenting my swap on my personnal web page once I get some free time to start on the write up. Again maybe some after xmas I will have this started as well.

Crawl under and have a look! My ZF has a metal tag on the side (I forget which side) of the case that says ZF, the model number, etc.
Note, the following is "to the best of my knowledge". Although I am fairly certain about the following information, I am not absolutely 100% sure. There may be exceptions I am unaware of.
1. I believe all ZFs have removable plates on the sides for PTOs. I don't know the Mazda trans very well, but I don't think it would have a PTO option as it was never intended for industrial use.
2. I believe all ZFs had an external slave cylinder while all Mazdas had an internal slave cylinder.
If I'm incorrect about 1. and/or 2., someone please correct me!

The M5OD never came behind a 351 from the factory. However, they will physically fit there, so it's always a possibility someone swapped it in there. The easiest way to tell the two apart is to look at the webbing cast into the case. Horizontal & vertical = M5OD. Diagonal webs = ZF.
As someone else said, it's expensive to convert a manual tranny to a 4x4 application. You are much better off starting off with a 4x4 trans, unless you want to rig up some kind of divorced t-case set up like the earlier F-250 4x4's had. They also used an NP205 for this.

ok i looked at the tranny and it says zf on it. it sounds like i'd be better off with a 4x4 version. do I need one that came behind a 351w? or are there others that will work? is the zf the same 5 spd they put behind the deisels? because i know a guy with a 89 or something f350 deisel with over 300,000 on it no problems.

You will need one from behind a small block unless you get one from a 460 then you could swap the main case as long as the 460 was a 4x4 trans. The deisel has different ratio than a gas engine zf trannys do.
