I recently have been doing alot of research on these trucks. I bought mine about a month ago and want to learn as much as possible. I am going to be puting a deeper trannsmission pan w/ plug on it. While researching I've found that a pan off of an old 727 torqueflight tranny will fit the 47RE tranny as well, well it should from what I've read, haven't tried yet. Anyways...You can buy a deep replacement pan for a 727 torqueflight for about $20 plus shipping. That was the cheapest I found. Now I don't know how much more fluid it holds, but it's 3" deep so I do believe it holds more and it has a plug, oh and it comes chrome. I'm thinking instead of spending $200-$300 on an upgraded pan for my 47RE, why wouldn't I just spend $20 for this one and still have a better pan than my stock one? Anyone have any input on this???

 

same pan. Alot of internals are the same as well.. until you get to the OD.

 

Yup same design with an hydraulic or electronic OD unit added to the rear end of it!

 

they use the same pan but once you get to the 48 it's a stock replacement on the deep pans that fit the 727. only about 1/2 qt bigger for the 47re. but yes they are cheaper than buying a mag or similar pan and you get a drain plug. I have the b&m on mine.

 

Cool. So its the deep pan for the 727 that's 1/2 quart bigger, or is it just the stock replacment pan that's 1/2 quart bigger? I know you can buy both a regualr replacment and a deep replacement. Also I'm pretty sure I have the 47re, but how do I check it?

 

The 48re came into play in the 3rd gens. the deep pan for a 727 only adds 1/2 qt well atleast the one I got did. B&M 10280 - B&M Automatic Transmission Deep Pans - summitracing.com says 4qts for all other aps but this pan was just put on a buddies 00 and they said only 1/2qt more but it's aluminum and has a drain plug

 

The deep pan I was looking at for the 727 was 3" deep. The one you've got says 3 3/8" deep. I don't think the stock one on my 47re is quite 3" deep. I would think the 3" deep pan would add atleast 1/2 quart or so to the 47re. Yours should add more than 1/2 quart. How did the new one look compared to the old one, depth wise? I'm just thinking if 3 3/8" deep only adds half quart, then maybe the $20 3" deep pan I was looking at isn't deeper than the one I have. But then what do they mean 4 quarts to all other applicable transmissions? Which transmissions do they mean?

 

I am not sure but it may be more than 1/2 at. I believe that the 4qts is for the 727 and 44? not sure though. but it's better than stock.

 

i got the pan with the cooling tubes in it from PATC tranmission......hold a few quarts over stock and is chrome and only 117 bucks......

 

Yeah it's better than stock and it's only $20 plus $12 for shipping. Can't beat that. I've seen the one with the cooling tubes, pretty cool design.
