my son has a 1987 f250 4x4 with a man. 4 speed and we need to know what tranny. it is as he needs to find some parts for it. any help in identifiing it would be great . thanks ron douglas it is a canadian truck.

 

4 speed, non-O/D should be the np435.

 

or it could be the borg warner T18

 

If it's got an aluminum top cover it's the 435.

 

To be absolutely sure-check the VIN sticker on the driver's side B pillar. It is visible when the driver's door is open. There will be a one letter code under the category of "Trans".

This is absolute-only if the transmission is still the same factory tranmission and hasnt been changed.

 

thanks for the help .now will go see what it looks like. thanks again p.r.douglas

 

depends on what engine it has also.
could be a NP 435, a T18 or a T19

 

NP435
will have an aluminum top cover


T18-T19

T18 had an un-synchronized 1st
meaning u can really downshift from 2nd into first without a little grinding noise

T19 all forward gears were synchronized
meaning u can easily down shift into first

 

The NP435 had an aluminum top cover and a PTO cover on the passenger side
The T18 had a cast iron top cover with a PTO cover on the passenger side
The T19 had a cast top cover with a PTO cover on both sides.
There was at least 2 different OD trans as well. One, reverse was up and to the left, the other has the typical "H" pattern with reverse down and to the right

 

I believe that only T18s were the only four speed factory installed with gas engines 87 thur 93.

 

i know it was T-18 for gas engines and T-19 for diesels, but i believe you could still get the NP 435 in 87as an option.
