I'm thinking of using a B&M Deep transmission pan on my 2006 ECSB with a 4L65E tranny and wanted to know if anybody has any comments on this pan. There is a filter extention pipe and a spring you have to bolt in to hold it in place. B&M makes good stuff but I have never used one of these. Can anybody comment on this.

I had one when I had a 4l60e. It was a nice piece and dropped the tranny temp about 20 degrees.

 

Why not get a larger external cooler? A while back i was debating on getting a Deep pan but found out a larger external cooler will drop the temps more than the deep pan will and it's generally cheaper. Just some food for thought.

However, when i do my first tranny fluid change i plan on getting a deep pan. But that won't be for atleast another year.

 

I already had a cooler. I wanted the deep pan for the extra fluid capacity. The lower temps were a bonus I did not expect.

 

Just curious, is there an advantage to having more fluid apart from heat dissapation?

 

I went up to Transgo and talked with their guys and they said that the 4L60/65E is already quite efficient and doesn't need a deeper pan, it only lowers temps by about a degree or so. A larger heat exchanger, however, is worth the money, as has already been said.

 

More fluid will help with cooling, but not by much. Its more the cast aluminum fins that will help dissipate the heat better. Having more fluid could extend your oil changes if you wanted and you'd get a drain plug so it's not as messy. I've also read having more fluid the tranny will hold temp for a longer time, meaning it takes longer to overheat, but also takes longer to cool.

Even though you have a stock cooler, i'd opt for a larger one. i went to a tru-cool 40K GVW and my tranny temps never go over 150 and i've sat in traffic with it for over 2 hours in ~85heat (winter never hit Southern CA). The real test will come when i start towing through the dessert in ~110F heat.

The B&M is a good pan, but i question why it uses a extension. Both the TCI and the Mag-Hytec deep pans do not require an extension and both use the factory filter. Some setups require a special filter when an extension is used. I called GM, TCI, and Mag-Hytec and they all confirmed that an extension is not needed with a deep pan on the 60E/65E. FLT said the same thing. I haven't talked B&M, if you do, let us know what they say.

 

Thanks for the replies guys
The pan I bought (above link) has no place for the filter to rest on so I think this is why it needs the extention so it sits on the bottom like the factory filter. I may not use it based on the feedback I get here.
I'm already planning on a bigger cooler to replace the factory one and I'm also going to put a Autometer temp gauge in the fluid out line from the transmission to see if there really is a difference between the factory pan mounted sensor (oil pan temp) and outgoing fluid temps. Some interesting things I learned while talking to the guys at Long/Borg Warner. The stacked plate coolers that are out there (Long makes them) are old technology. They told me that the 8X11X 1.5" cooler they make (which a lot of companies sell under their own name) is not as efficient as the factory 10X4.5" tube and fin cooler found on a stock late model Chevy/GMC truck. They also told me GM is having trouble with lack of lubrication in very cold weather climates because there is no bypass in the cooler to allow the cold thick fluid to circulate and it's starving the tranny until the fluid heats up. Just thought I'd throw that out there.
