[Big Blue 89]

I currently have a 1989 with a 351w and an automatic. I was wondering first off which automatic I have in it. Second I was thinking of swapping out the automatic for a stick to get that granny low, preferably a np435. What years would be good for the donor parts or maybe someone has one to sell around the reno, nv area? Thanks

second part i cant help you but does the tranny have OD? If it doesnt it is a C6. If it does it is an AOD

not AOD, didnt come mated to a 5.8 from factory so it would have to be an
e4od or C6 like said above.

E4OD hit 250's and 350's in 90 and 150's/BKO in 91 I think. So itwould be a C-6/AOD depending on overdrive.

 

[No4Low]

The C6 was replaced by the E4OD which was modified to include a fourth forward speed and electronic shift controls, replacing the hydraulic control mechanism of the C6.

Applications:

1989–1998 Ford F-Series
1989–1998 Ford Van
1994–1996 Ford Bronco
1997–1998 Ford Expedition

I stand corrected, it appears that the E4OD showed up in 94 for the BKO

 

[TravisITGuy]

the e4od was around in late 89 mainly 90 for the bronco

EDIT: kemicalburns beat me.

There is no overdrive so I assume its safe to say its a C6. Now would putting a transbrake or a manual shift valve body help with downhill braking? That is the main reason I was thinking of swapping in a np435, well that and the grannylow.
