Lately I have been looking at ways to prolong the life of my transmission, and as well as getting a cooler, I have stumbled across these. B M 70260 Deep Transmission PAN 4L60 4L60E VR VS VT VX VY VZ Holden Commodore | eBay The concept is pretty simple, more fluid takes long to heat up, and excess fluid in the pan will stay cooler. The pan claims it will increase the capacity by 2.4 litres. The drain plug on the bottom also makes it easy to quickly change a few litres whilst I'm changing oil, without needing to drop the whole pan. The only thing I'm unsure about is where it says it comes with a filter extension for applications where the filter needs to be close to the bottom, would I need to worry about that or doesn't it matter? Could I still use a normal transmission service pack like this, Auto Transmission Filter KIT Holden Commodore VT VX V6 V8 Trans Service 4 SP NEW | eBay or would I be stuck getting stuff like these ones, Automatic Transmission Filter KIT Suit Holden Commodore VX V6 V8 With Deep PAN | eBay Also, has anyone got a deep pan? Reckon it's worth it?
