1996 F250 7.3 Transmission cooler

Hi everyone,

I am planning on upgrading my stock transmission cooler and took a look at my current setup.

Is the OBS 7.3 transmission cooler the rectangular finned cooler located behind the front bumper on the front passenger side? I have seen the Super Duty stock transmission coolers and they are flat, smaller versions of the 26-31 row coolers. I am hoping the rectangular finned cooler is the stock trans cooler, as it is easy to access and swap out.

I was looking into the Tru-cool 4739-1 cooler.

The tru cool is a great unit. Look at the transmission and follow the lines to make sure you remove the correct cooler. The very small like 6in by 6 in is the powersteering fluid cooler but again. Follow the trans fluid lines to make 150%.

The Tru-cool is a decent cooler. Another very good option is the Ford OEM 6.0L trans cooler. It is nearly a direct fit on the 94.5-97 trucks like it is on the 99-03's. I've installed a few on the older trucks and I have custom made adapters/kit to go from the stock 5/16 lines to the 1/2" ports on the 6.0 cooler

DIRECT REPLACEMENT FOR 04-07 MODELS FITS 99-03 THAT CAME WITH SMALLER TRANSMISSION COOLERS. SOME MODIFICATIONS WILL BE REQUIRED TO TIE IN THE LINES FROM THE TRANSMISSION TO THIS COOLER. DRAMATICALLY REDUCES TRANSMISSION TEMPERATURES TO INCREASE THE LIFE OF YOUR CLUTCHES, TORQUE CONVERTER, AND...

Should I be prepared for some trans fluid to drain out when disconnecting the stock cooler? I haven't found any decent write ups or videos of the OBS stock trans location / removal etc..

I don't want a mess on my driveway or get my wife upset!!

Yes, some will drain out, but not a whole lot.

As for a write-up, it depends on which cooler you are installing.

Hi everyone,

I finally was able to tackle this job this weekend. I just wanted to post my approach to the transcooler upgrade that I mounted behind the front bumper, behind the front license plate area.

The last photo is the stock transmission cooler on my OBS F250 that I had a difficult time locating.

Thank you for all the help and advice.

Just an update.

I have been driving my F250 for the last 2 days with the trans temp staying within the 140-160 range. This is a big improvement compared to the stock transmission cooler temps pushing 200+ while daily driving.

I appreciate all the help and advice.
