t18 4 speed bolt up 2 a powerstroke?

[ozzy460]

ive got a 95 f350 with a powerstroke and a 5 speed. 4x4. reverse doesnt work. doesnt engage all the way and pops out. ive got an 84 f350 with a 6.9 4 speed here. will the 4 speed from the 84 hooked up to the 6.9 bolt up 2 the powerstroke? if so what do i need? not worried bout 5th gear as i never use it. just sick breaking these zfs.

There is a guy up here by me that has one behind a powerstroke, but I dont know if it was a direct bolt up or if he used an adapter. Would be one powerful beast with that 4 spd behind it

[ozzy460]

if yu could get any info on that would be awsome. this is a work truck no highway driving. all offroad w heavy loads. 5 speed just dont hold up.

Or you could always put a 6spd in it.

The four speed should work, I've seen it done the other way, with putting zf5 behind a 6.9, you just need to use the right flywheel/clutch combo. Keep in mind 2wd and 4x4 trannies are not easily interchangable. The two transmissions are very close to the same length from what I understand, so you shouldn't need to adjust driveshaft length(s). Do a search for five speed swap into an idi, you'll find more info on what's involved.

in my experience the zf is stronger than a t18 trans, how do you keep breaking the zf?

In my experience no other trans holds up like a 4 speed. I have to get more info on this subject, man I would love to have a 4 speed behind a powerstroke

I get their tough but Ive run both and with my abuse. 3.55s 37s WOT clutch drops in 2 feet of mud or on dry pavement I cant hurt the zf trans. So this guy is truly a beast among men if he is breaking them.

[Fordman247365]

2 different experiences =). mine are mostly bad with the zf5 and all good with the 4 speed. The main thing I dont like about the 5 is the gearing. Does the diesel one still have the super high reverse gear where you can do 40 mph?

[rolsmojave3]

My truck might go 10mph in reverse. It's very low, I've never driven one that was fast in reverse with a manual. I have driven an auto that went waaaaay to fast in reverse, why you would need to back up that quickly is beyond me.

What is happening to the ZF's? Are you rebuilding them to specs?
