    10 degree drop in temp for 7.3 Excursion

    Posted by Steven Hockman on Mar 12th 2019

    I installed the Mishi trans cooler in my 03 Excursion 7.3. Installl went quick with the 7.3 to 6.0 adapters (you need 2). So far I'm getting a consistent 10 degree drop in trans temps. As always great service from Riffraff!

    Best trans cooler

    Posted by Jake on Jan 7th 2019

    I installed this cooler on my 2001 f250 and the fit was easy and clean. I had removed the front clip from the truck to replace with a new one so getting the new cooler into its place was not an issue at all

    Big difference

    Posted by Unknown on Sep 13th 2018

    Installed this on 7.3l and replaced the small cooler and running 30-40 degrees cooler around town and towing. Also heats up much slower. I am running it with a deep tranny pan too. With the deeper pan it ran 5-10 degrees cooler but warmed up much slower so with this even slower to heat up and much cooler. Very happy and easy to install. Quality product.

    Fits like a charm

    Posted by Unknown on Jan 26th 2018

    I was a little off set by the reviews on the web of this unit going into a 00 7.3, like had to re-drill for their truck, my install was simple bolt up along with 1/2 inch to 3/8 inch hose adapter's and I'm running cooler all the time, I haul light regularly but still a 110 - 120 degree trans temp while towing is great.

    Best upgrade

    Posted by Samuel on Apr 20th 2017

    I installed this cooler on my 2001 7.3. This should have been the first upgrade I did to the truck. For the cost and the difference it makes if you pull get one. Trany runs cooler now when pulling than it did before when I wasn't pulling. Huge drop in temp 50+ degrees. Was easy to install after removing the cross member under front end to get at lower two bolts. Not a big deal at all. Only parts I had to get was the 3/8 to 1/2 barbs and a few foot of trany hose.

    This is a Bernie cooler: it's huuuuuuge

    Posted by Chris on Mar 22nd 2017

    Cooler showed up fast like always. I removed it from the package and was impressed on how well it was shipped. Install was a breeze all the holes bolts etc. everything just lined up. the new cooler dwarfs the stock one. I was able to drop temps by at least 50 degrees. I have a road trip coming up and the last thing I'll be worrying about while driving is my tranny temp. If you pull anything do yourself and your transmission a favor and buy this cooler.

    Awesome deal on a good quality product

    Posted by Unknown on Mar 13th 2017

    Ordered it on a Saturday morning paid for 2 day shipping they had it on sale and it ended up costing a lot cheaper than any other website or dealer. Had it on Wednesday morning very well packaged and no damage happened during shipping. Awesome customer service and never have to worry about a lost or damaged order when dealing with clay
