Simply stated, more is better when it comes to transmission fluid. The more fluid there is, the cooler the transmission runs. The cleaner the fluid stays, the longer the transmission lasts. That is why you need a PPE Heavy Duty DEEP Aluminum Transmission Pan for your Allison transmission. But wait, there is more! Large 7/8 inch cooling fins outside and internal heat sink fins reduce transmission operating temperatures up to 40 degrees.
