what is the better 5spd tranny that came the new process on or the other one

 

New process is a 4 speed, at least the 435 is. There was a Mazda 5 speed, which came in the F150's, and there is the ZF 5 speed that came in the F250's and up. ZF's website lists the ZF in 351 F150's in 88 only, so that might be a possibility as well.

 

Yeah, I keep hearing that in 1988, you could get an F-150 with a 351 and a ZF 5 speed. I've yet to see one, or hear of anyone with one. Not saying it never happened, though.

 

I've never seen one either; I'm just going by the documentation on ZF's website.

 

I've seen it in about a dozen other places, too. Napa parts catalogs, web sites, etc. It's sometimes called a M5OD-HD. Not that there's any such thing, but that's what I assume it references.

 

I'd like to find an f-150 with the 351 ZF stock. You talk about a half ton truck that would last a long time...

 

back on topic plz

 

In a way, that was on topic there Gameover. I was telling how the ZF is a great transmission, and if you will read the other fella's posts you will get more information on the transmission.

 

Couldn't you just swap in a ZF from an F250 w/351 in place of the Mazda?

 

That is what I am doing. A freshly rebuilt ZF, new 351, and while I am at it, I am rebuilding an 8.8. New trucks don't have all of the option that I want for a price that I want, so I am making my toy truck from a 94.

I like the gearing of the ZF and if you read around here, the reputation will speak for itsself.

What are the gear ratios 1-5 of the ZF vs. the Mazda?

 

The mazda gearing is as follows:

1st - 3.90
2nd - 2.25
3rd - 1.50
4th - 1.00
5th - .80

ZF:

1st - 5.72
2nd - 2.94
3rd - 1.61
4th - 1.00
5th - .76

That is for the sbf ZF, the 460/444 might be slightly different gearing.

Good luck,
Mike
