    Hello all,
    I drive a 2015 RAM 1500 express 4x4 with a 3.6l pentastar and the 845RE transmission. I have 48,650ish miles on it. I upgraded my transmission pan this weekend. I upgraded to a ppe aluminum pan with removal filter. The pan fit great. The truck was down shifting hard/jerking. I did a drain and fill flush on the system twice. The transmission now down shifts smooth. The fluid i took out had a burnt smell to it.

    you will need a allen wrench 5/16 for the fill plug and t40 for the drain and all the pan bolts.

    PPE transmission pan.

    You can use Maxlife atf on zf 6 and 8 speed transmissions.

    I did this becuase now i can change the filter and fluid cheaper than buying a new pan/filter and the lifetime fluid. The third party pan/filter is 270.00 and the fluid is $52.80 a quart. yes it costs alittle to set it up at first. but the replaceable filter is 29.99 and the maxlife is 17.99 a gallon at walmart. I plan on keeping this truck for a while. so this is an investment for me. I can tell you that my transmission shifts like it was new. The PPE pan is top notch.
    None of the transmission shops around here will touch the 845RE. the rebuld kit cost 4,800.00. A new transmission cost 5,000.00. plus lador and tax. this is a small investment that fixed my hard down shifting. So after a couple of filter changes it has paid for itself. thanks
