Deep pan I have a 2004 pontiac GTO with a built 4l60e. I'm thinking about going with a deep aluminum pan like the B & M. With the deeper pan do I need a different filter than a stock replacement? Also do I continue to use my stock dipstick?

Dipstick will be OK as is because fluid level will still be at the pan gasket. The deep pan may come with a filter adapter to move the pickup down lower. Make sure you have ground clearance for a deep pan. GTOs are fairly low slung.

Most people use a steel deep pan from a truck, something like this Dorman 265-811 and a stock filter for said truck deep pan. This Dorman pan on Summit is $50.95. I don't like the drain plug on the Dorman pan but I'm sure you can find others from places like Rock Auto Jegs and Amazon. I welded over the plug and moved it to the side. It has been on my Firebird for years without any issues.

Turns out the oem GTO filter with the extension B&M provides with their pan is too deep. I'm hitting the filter way before the pan sits flush with the gasket. Apparently the GTO uses a deeper pan than other cars with the 4l60e. I guess I need the fbody filter with the extension for the B&M pan.

I had a 2-3 shift flare. It’s hard for me to say for sure after a couple test pulls because of tire spin with the f1a-94 on an Ls3 block with forged internals, but it didn’t seem to flare on a 2-3 shift during street testing yesterday.
