Allison Bar and Plate Transmission Cooler

Excessive heat is the number one contributor to transmission failures and can cause clutch pack slipping, clunky shifting, fluid breakdown, etc. Constant overheating can reduce the transmission service life by 50% or more. The PPE Allison bar and plate transmission cooler provides the proper cooling that your transmission needs to stay healthier and longer.

The PPE all-aluminum transmission cooler features a massive 262 cubic-inch core – that’s 3.8 times larger than the stock cooler. The 2.7x larger frontal area increases its airflow exposure, enhancing heat dissipation. Its dense, louvered external fins maximize heat transfer to ambient air, helping achieve a temperature drop of up to 45°F to keep your transmission within the optimal temperature range – even under demanding conditions.

The PPE cooler’s bar and plate construction is a heavy-duty upgrade over the factory stacked plate design, delivering significantly greater cooling mass and flow capacity for true performance gains. Its all-aluminum build also offers superior pressure resistance and durability, making it ideal for performance applications.

Installation Guide:

Cooler Trans 2001-05 GM Allison Bar and Plate

PPE bar & plate trans cooler

First thoughts when I the cooler showed up I was surprized how heavy the box was I used other trans cooler before and they where very light weight.
The Cooler seams very well made everything fell into to place all the mounting holes fit perfect.
It took 30 minutes from start to finish to get it installed no leaks.
So far it seems great it right now it is winter time and I willn't find out until summer time how cool will keep my trans but it looks like it will do the job very well.

High quality, works Great, easy install.

You definitely get what you pay for! I really debated spending the $ on this vs buying a big universal cooler. This is one nice piece, u can definitely see why it cost what it does, and it’s worth it. I installed this on my 2001 Crewcab Chevy 8.1L/Allison powered Ramptruck car-hauler.
This made a big improvement in trans temps, 20°-40° degrees lower than it was before on the same trip to the mountains pulling the same load. It never got over 200° and it only got to that once on a steep grade. On the trip we took to Florida and back (flat ground) rainy and cooler outside temps it never broke 150°-160° degree trans temps. I had slight concerns over it blocking radiator air flow but the cooler trans fluid actually brought my engine temps down about 10° as well.

Installation was super easy as well, only took about half an hour. I did have to remove the center grille mount plastic clip bracket, but it unbolts and I moved one other bolt so that the cooler wouldn’t rub anything.

Overall, I very happy with my purchase! I ordered through Summit because it saved a little $ and I got free shipping, but even called PPE directly before ordering to ask some fitment questions. I ordered this and the PPE external spin-on trans fluid filter and installed them both at the same time.

If you’re debating, spend the $ it is worth it; you won’t regret it. Even the packaging on this was nice and it was well protected. It’s plug and play 2 quick-connect fittings and bolts right in.
