Powerstroke ZF5 behind a 6.9 IDI?

Alright, I am done searching and Imma just ask the experts. I can't seem to get a definitive answer on this in my searching so here goes.

I'm parting out a '95 F250 4x2 with a ZF5 and a PSD, and a guy has approached me about whether the ZF5 from the PSD will bolt up to a 6.9 IDI. I think this is doable, but I don't want to steer him wrong just so I can sell my transmission. So clear me up on this. Can it be done? Any complications to doing this?

Thanks in advance.

well iv'e taken a trans from a 93 IDI and bolted it to a 95 Powerstroke and the bolt pattern for the 7.3 IDI is the same as the pattern for the 6.9 so i would say yes its doable

Wow! That was quick! One vote for "Yes you can" (and that sounds pretty conclusive to me). Anybody else want to second the motion?

I am not what all years fit, I think the bolt pattern is the same on the ZF5's, but the six spd is different and those came on 7.3 strokes too.

Yeah this one is just the OBS 5 speed ZF5, I just wasn't absolutely positive that the bolt pattern of the 6.9 was the same as the 7.3 IDI and the 7.3 PSD.

Yup, 6.9/7.3 IDI and 7.3 PSD in obs apps are all the same pattern, my 96 F250 has a 94 IDIT trans behind it, and my F350 has a Hybrid, 96 guts and rear half and a 90 case.

The trans will bolt, but there is no provision for a speedo in the 92 and newer trucks, as they get the speed info from the rear axle.

X2 if it is two wheel drive he will not be able to hook up his speedo.

Good call. I will be sure and let him know that this is the case. Is there a work around for the speedometer? Thanks again for all the info.

If his truck is a 91 or older, there really isn't a good way to get the speedo hooked up. The hole is cast in, but not machined out. I don't know if the shaft has the provisions to put a gear on it.

Throw a $100 GPS on the dash to use instead of a speedo?

LOL That will work for speed, but doesn't do much for the odometer.

Actually they have odometers in them as well, as long as they are on when the vehicle is being moved. Also if you are using them for maintenance intervals, they have to remain specific to the vehicle, and not moved around.

I noticed last week that my car gps rolled over 50,000 km's, (30,000 miles) and it's about a year and a half old. It doesn't always get turned on either, but it has been bounced back and forth between a couple of the trucks.
