While the vette was on the hoist i noticed that auto transmission was not level but tilted up at the back, I would like to deepen the pan so that it stays the same at the front but 1" deeper at the back. To do this i need another pan, would the pan off a VN-VP gearbox be the same as the vette pan. Not only would this give me extra oil but the oil level will be below the pan gasket.

I think one of the things you might have to consider if the trans you're talking about is a 700R is the fact that the pan actually holds the internal filter in place. From what I've been told when I was buying an after market pan, a deeper one would be unable to keep the filter in place. I don't know this to be fact but I can only go on what I was advised against. Hope this helps.

That I did not know, I will contact the auto trans place. Thanks. If the pan is deepened a "U" shape bracket could be welded in position to hold the filter up, there would be a way, I will make some enquiries and get back to you, but I am sure I could make this.;26

You apparently need the filter tht goes with the pan.Check for ground clearance as there ain't much room under these cars.

The pan under the C4 of alum and to do what I would like to do I would have to get one from a VN/ VS commodore which is pressed steel. I would not deepen the front of the pan only the back by 30/35 mill. Really I need to see a auto box with the pan off. and work it from there.

This is how I saw it when the vette was on the hoist, if the vette gearbox was in a Commodore the pan would be level, as in a vette the back of the box is high than the front which means all the oil is on the pan gasket at the front and if you have a bad leak you loose most of the oil. My idea is to get a steel pan off a VN/VS commodore and cut where the pan starts to roll under on both sides and back, force the pan apart about 25 to 30 mill mig weld in a new shaped piece. The only problem is holding up the filter. Before cutting and welding the pan needs to be bolted down to stop warping. :b2:b4:b4:b2;eek;27
