1988 and up F150 trans...

[Andylad13]

starting in 1988 the 300 block got the 5 speed manual trans instead of the 4 speed manual. i beleive both were made by borg warner. my question is, is the 5 speed called zf5?

 

[MUDKICKR]

it was more of a mazda design, but i think people do call it a zf5

It is probably the light duty mazda M5OD transmission. the ZF trannys would have been restricted to the 250's on up since they are a beefier design.

i checked the gears vendors website for the trans gears, and for the 5 speeds they only have zf5's. thats why i was asking. where can i get the gear ratios of the light duty trans?

Clicky

Needless to say they have a few options, but they are relatively close...

3.91, 2.24, 1.49, 1.00, 0.80 M5ODR2 which is made by mazda, internal slave royal PITA to replace. rubber plugs like to dryrot and seep oil killing the syncros and eventually leading to trans melt down. decent trans for a DD, poor reverse for backing trailors or any heavy use.

4 speed was dropped for 88, came back for 89 (t18)

^^Thanks for the info guys! i would still want the 5 speed though, just for that od. even though its only .8.

the ZF was made in a small block bell housing which the 300 is part of. found in F-250HD and F-350s usually behind a 351.

i dont even remember what the original question was but, is this question related to a truck u own with a 300? i love mine in my 93!

The F150's got the M5OD R2 (Mazda) and the Rangers, Broncos, Explorers that were 5 speeds got the M5OD R1 trannys. Now I believe that the F250's with the 300 I-6 did get the ZF5 I think but that is because they were 3/4 ton trucks and where for heavier duty use.

 

[Optikalillushun]

not nesseccarly, almost every F-250 with a 302/5 speed had a mazda. the 300 was either or, usually the LD F-250s (semi float rears) had the mazda.

 

[FORDMAN41291]

you may be right. what exactly do you mean semi float rears?

 

[Optikalillushun]

like the rear axle in ur F-150, no removeable axleshafts like most F-250/350 or semi truck style axles.
