    I'd be scared. I like that aluminum one, but not the price. I recently did mine with the felpro gasket, with just a thin layer of sticky red grease on both sides to help it find its home. Hasn't leaked a drop.

    I use right stuff for all my gasket sealing but the pan on there now looks a bit crusty ...

    A few years back I replaced my OE tranny pan on the 02 with a Dorman. OE pan was crusty and PO must have overtorqued the bolts as it was a bit warped and didn't seal well. No drain plug in the replacement but the thickness and coating looked to be just as good as the original. Worked great until I got rid of it.

    Recently dropped my trans pan for service @ 87k on my '02 with a 45RFE transmission. It appeared to have been the first time the pan has been removed. The pan was in good shape overall and has the ridges between the holes. It was sealed with black sealant only, no gasket. The sump and spin-on filters were both Mopar stamped.

    Inside the pan was clean and the magnet had a small amount of fine pieces of metal adhered to it, looking like a small fuzzy doughnut.

    I ordered a Wix filter kit as a replacement. One filter made in China and the other in Mexico. The gasket was a black rubber type.

    I installed the new gasket ring for the pan filter- was a bugger to get the old off. Installed filters. Installed gasket mated to transmission, and Black RTV on pan. Torqued into place as per RTV directions for curing time.

    All turned out well thus far with a re-torque follow up soon.

    I considered a new steel stamped pan with a drain in it and also the drill-in plug kit. Ultimately decided against b/c I didn't feel comfortable with a flimsy bottom mounted drain plug in thin sheetmetal.

    Reason I did this service: Other than not knowing the service history, the color of the ATF+4 fluid was a dark color. It did not sit well with me.

    Since the service, the transmission does feel somewhat smoother.

    My appologies, i did make another phone call to a guy that i know who works on transmissions for a living. According to him some of the earlier uses of the 45RFE in Dodge/Chrysler vehicles did use RTV sealant for the pan.
