I have searched all over and can't find any where that says which trans I have. On the door sticker it has the letter F under Trans.

What year is your truck? Is it a manual or auto?

Assuming it is a manual transmission it is most likely a T-18 four speed. Scroll down this thread: Ford Truck Transmission Info - Delta 4x4 Club - Forum Home

if it's a 5 speed you most likely have the zf-5spd... The prefered 5 spd tranny for our trucks... tough and has a granny low for pulling.

T19 if it's a 4spd...

If it's an F-250 it's a T-19, not a T-18. It has a higher 1st gear than the T-18 and it's also synchronized.

The door code has the letter F I'm not sure on the four speed or five speed because the shifter is missing the *** and its screwed up so it is useless I guess I'll find out when I go to fix the shifter.

T19 was a top loader tranny with a removable bell housing and a PTO take off. The zf was not. The bell housing was part of the tranny.

Domestic Truck Tranny Guide

If i remember right 1st gear in the 19 is farther forward than 3rd gear. If you can get it into 1st and 3rd that might help.


ZF



T19

Since when did they put a T-19 behind a 300? I thought the T-19 was only behind the 460 and the diesels?

It also depends on the GVW. I've seen the Mazda 5spd in some light duty F250's. I've also seen one with a NP435 ( one I owned ) .

there are two version of the m5od as well. the r1 which came in the explorers and rangers, and the r2 which was the light duty truck tranny. I dont think it was ever offered in a 250 though.

I thought they stopped using the np435 before 87 but i dont know when the t19 stopped. I also dont know if they put a zf behind a 4.9l. I have seen 4.9l 4speed 250s but never crawled under them to see what tranny they had.

snap a quick picture of it and we can tell right away.

I have seen multiple light duty F250's with a 300 and 302's that had the mazda 5spds in them.

You could get a ZF 5spd with the 300.

Nope, I have personally owned a 87 F250 that had a 302 with a NP435. And I had a 91 F250 with a 300 and a NP435. Neither appeared to be swapped in. I've also had a 91 that had a T18.

Not with a door code of "F" it isn't.

The M5OD-R2 was offered in the light-duty F-250. Since this truck is a 4.9L, it *could* be a light duty and the M5OD was intro'd in 1988.... so if it weren't for the door code, it's possible.

From what I have read, the NP435 was last used in '86. The T-18 was available in the F-150 up until 93 so I suppose the T-19 was around into the '90's as well although I've never read anything definitive on that.

They were both used. It depends on the GVWR. Greater than 8600# trucks got the ZF.

This is true.

Also true.

It wouldn't be the first time Ford made an oddball truck out of leftover parts that were "supposed" to be discontinued. With Ford, anything is really possible.

But you will look long and hard to find another factory-installed NP435 after 1986.

I've owned enough different Ford trucks that I learned never to say never about most things about them.

But the T-19 behind a 300 stock is still one I haven't seen in person yet.

The NP435 is my favorite transmission so I have a tendency to hang onto the transmissions when I find them. Even though I've never had to replace one yet. I've got my own little collection of NP435's, T-18's and T-19's in the back corner of my garage.
