I have a 86 f250 6.9 4x4 auto and I want to put a standard transmission in it.

Im wondering what options I have for a transmission. Im pretty sure they came with the a 4 speed standard transmission. Im wondering if there is a 5 speed transmission that fits?

also will a 4 speed from a 2wheel drive 6.9L work in a 4x4?

 

Yes yes and no. you can use the T19 4spd, the ZF5 5spd you could even use the zf6 6spd. from a SD 7.3 psd

2wd trans will not work with a married t-case at any rate, best to stick to 4x4 trans. Except, the F-superduty ZF5 is actually a 4x4 trans with the driveline brake in place of a transfer case, so you could find one of those.

 

so can i use a zf5 from a gas truck? 305 or the 351?

 

No, the ZF5 for the diesel has a spacific bolt pattern that fits the diesel only. But you can use one from the 87 6.9 threw the 97 7.3 Powerstroke.

 

ok great.

Thanks
