DERALE Transmission Oil Pan for A4 700R and 4L60E - Photos and impressions

Subject: DERALE Transmission Oil Pan for A4 700R and 4L60E - Photos and impressions
by biggrizzly on 2011/5/6 13:38:03

From the very onset of me deciding that Pete Kane would rebuild my transmission I have planned on buying the DERALE deep oil pan. Well, the big "brown truck" stopped by the house the other day and dropped one off at my front door. It was delivered from Summit and with shipping and handling came to just under $150, which for the quality of the pan is pretty darn incredible. Packaging was stout and everything in the box was neat and in its place. I like the pan gasket that came with it. Its not cork but synthetic. It seems to be nice and thick. Hopefully it seals as good as it looks.

The most prominent feature of this pan over other pans on the market I looked at, is the fact that it has cooling tubes that run from front to back which allow air to pass through providing a cooling effect to the fluid that is surrounding the tubes on the inside of the pan. I have not seen any specific science to the efficacy of this cooling technique but it sure seems to make sense to me. I know that B&M offers cast pans that have cooling fins and they probably work OK too, but I wanted to steer clear of a cast pan, in the event something should hit it and cause a crack and subsequent hemorrhage of fluid. Also, those pans are almost twice the price of the Derale.

Additionally, the pan came with a magnetic drain plug in the center of the pan which is practically strong enough to hold the whole transmission up by itself... well maybe not that strong, but it will catch any metallic objects that comes its way. Also, there is a bung and pipe plug provided on the side of the pan for a temperature sensor to remotely monitor transmission fluid temperatures.

I haven't mounted it yet, as Pete left the stock pan in place with no fluid in the transmission and the bolts just finger tight. He knew I would be installing the Derale pan after the transmission was mounted and hooked to the drive line. All in all I think this is a quality pan for the money that should be good for some cooling effect and make up for the transmission fluid I lost by going to a smaller diameter converter.

I hope this helps others that might be considering this mod. I'll follow up to this later after the car is on the road a while.
