B&M transmission pan for the 8HP70 and 8HP75

[Wild one]

Why is the filter part of the pan anyway? Can't someone make it separate?

The PPE and B&M pan have a replaceable filter,and i think some of the cheaper aftermarket composite pans have a replaceable filter

Did I miss something on the holley page? Where would you get a replacement filter for that B&M pan?

I'm guessing you've never experienced the thickness of the factory ZF fluid,water is damn near thicker then the factory fluid.I highly doubt there'd be a measurable differance in the milege by dropping the fluid temperature 5 to 10 degrees.But there's probably a measurable differance in the life of the transmission. Point being the HD trucks with the 8 speed hardly ever get over 170F while towing 7,000+lbs,they seem to run more in the 165 to 168 range,while the 1500's will run on average 20 degrees hotter,so their must be a reason the HD's run cooler,and i'm guessing it has more to do with keeping the 8 speed alive. I know the PPE pan pulled close to 5 degrees out of my 8 speeds operating temp,so i would think this pan would do the same or more,and i couldn't see any change in the trucks milege,in fact i can't even see any measurable change in milege on a 500 mile trip,with the transmission running at 140 which is where it runs at now. Maybe over a 100,000 miles you might see a bit of milege differance,but i even wonder about that.On a cool day (30 to 40F) and a easy drive,my wifes 6.4/8 speed Challenger will take well over 70 miles to even crest 120F on transmission temp,and i can still pull down 31/32mpg with it,basically the same milege it'll get with the transmission at 170 to 180F. If you do any towing i think this pan or the PPE pan are good investments,just for the fact you have more fluid volumne to absorb contaminents and heat spikes. You should buy this pan and report back on whether you see a milege drop,as right now this is all speculation,and you could be the one to try out your speculations

Well crap! My 8 speed must be bad then! It usually hits ~190 around the same time as the oil. Maybe a little slower. But over my 30ish mile commute to work during rush hour on the "highway", all 3 fluids hit around 200. Running empty on my 5.7

That's about normal on the 1500's,as they use coolant to heat the transmission fluid,the HD trucks and cars with the 8 speeds don't pre-heat the transmission fluid with coolant.The only ones heating the 8 speeds transmission fluid are the 1500's.

That would explain it! It did seem odd that the tranny got warm so much faster than the oil.

Current temps. Been driving for over an hour. Cruise control at 80mph. Just pulled off to the rest stop.

Crazy how much difference the shudders make on your temps. Mine generally settles around 140 to 145 on the highway.

The ppe pan uses the stock transmission pan gasket instead of the cork gasket so it’s really easy to find a replacement gasket if needed.

Here's a reply from holley after I inquired about purchasing replacement filters.

Hello Shawn,
We offer replacement filters that would allow you to get a replacement filter when you need one. This is not something that should be hard to get, most of our dealers should have or have no issues getting a replacement filter.

Thanks,

I still don't see any available for purchase on their website. There is a part number listed in the instructions manual. I don't think the gasket material choice and the unclear source for filter replacements are worth saving $20 over a PPE.

I'm having my crossover and factory connector pipe rerouted next week. After that, I think I'm going with the PPE to prepare for my next fluid change.
