I considered it but I was really turned off by the cork gasket

I'm sure you can still use the OEM gasket

No, I don't believe so. The factory pan has a channel in it that the gasket fits into. The B&M pan has no such channel so the factory gasket can't be reused. The PPE pan has the channel and uses the factory gasket, I'm pretty sure.

Anyone have a pan with a DIPSTICK yet?

Has anyone talked about the cork gasket separating the pan from the transmission, therefore preventing heat soak from the transmission to the pan? Thoughts?

That's not even a thing but personally, I would not use a cork gasket

Real use case / summary after installing it & running the B&M pan for the last 5,500 miles: it might be the best $350 for any aftermarket item I've ever spent. My trans temps are running 15-30 degrees cooler than the OEM pan. That isn't a typo. My rig is a 2022 Rebel ecodiesel and, prior to install of the B&M pan, once getting to operating temps, both around town or on back roads and on the highway and at highway speeds on long road trips (generally flat, with some travel in the Appalachian mountains), with the OEM pan and fluid I was logging trans temps in the 203-212 degree range depending on type of road/driving, ambient weather conditions, etc. Post-install, I'm in the 183-188 range upon getting to operating temp in those same driving conditions as with the OEM pan & don't think I've ever seen temps hit even 190 degrees. No leaks with the gasket & with the drain & fill plugs, super easy for future drain & fills. To be fair, 2 caveats: a) I've also replaced the OEM fluid with AMSOIL's 'Signature Series' ATF over the course of 2 drops and drains (rough math says I'm now running 90%< AMSOIL ATF & <10% of the OEM fluid in the entire unit... so the change in ATF is an unknown variable that may (or may not) be contributing to the far-cooler running temps-- I doubt it, but want to be transparent & thorough as possible when I post things on these very helpful fora and b) I haven't towed 11k with it in the Rockies, so can't speak to every single use case / condition... but semi-regularly I am at max or near-max payload & still have never seen trans temps reach 190. 15-30 degrees cooler at operating temperatures is the best $350 I've spent on my rig to date. I considered the PPE pan, but the cost is approximately the same and a) the PPE pan holds less fluid than the B&M pan and b) with the PPE pan, you must buy a custom transmission filter made by... PPE. With the B&M pan, you use the OEM filter. PPE seems to get a lot more love in the forums, but I've been super-impressed with the B&M pan. Have no basis for comparison in running a transmission cooler as to which is better.

How exactly do you use an OEM filter with the B&M pan when the OEM filter is integrated into the factory pan? Little research and the part number B&M gives you leaves you empty handed when buying a replacement filter. But others have been resourceful enough to figure out what filter B&M uses and gives the application. So that's a strike against B&M in my opinion. I can order a new PPE filter from PPE website, or any number of other places that carry them by using rhe lart number PPE gave me. No further searching required.

Cork gasket is another strike IMO. And no other alternative being available just sucks.

Not trying to knock the B&M pan too much, I have one on my 2000 Dakota R/T and it's a great pan, that actually uses the factory filter for that transmission Just seems like they dropped the ball a little on this one.

As for your cooking running temps, the increased capacity and fresh fluid probably play a big part in that. Since I've had my PPE pan in, I've only seen temps over 190 once, and that was doing slow speed off road course in 4wd, and it hit 225. Daily driving it ranges from 185 around town to 175 at highway speeds.
