The Money Pit

I finally got my 700r4 rebuilt,and knock on wood,so far so good.I am taking it easy on this one,but the otherday I couldn't resist and ran the tach up to 5000 in second. For a few seconds I thaught I blew this one as the car lost power and I let off the gas and coasted while I shifted into neutral,then back into OD/drive.I suspect under high G's and a few rpms the transmission pump is sucking air,losing it's prime and that's exactly what happened with the last transmission,except I was turning 6500 rpms when that went kaboom.

Anyway I thaught running a deep pan would help prevent pump starvation if that's what's happening,and though ground clearance needs concideration,would this be worth a try?Anyone?

I'm using the "durale" (not sure if I spelled correctly) deep pan with the hollow tubes. My car is slammed as low as I can go.
The pan touches only on high speed bumps if I don't take em at an angle.
I would recommend the deep steel pan verses the aluminum.
Steel will dent a little when it touches....Aluminum will crack and leak.

Cappy is right about steel. I have the Art Carr cast aluminum. it holds another 1/2 gallon over the stock pan and it's good point is the magnetic drain plug.

It's still higher than my header collector flanges

Are there high capacity pans that are wide rather than deep? Like you see with oilpans. Or would that have to be custom made?

Here is a picture of the Derale pan that Cappy talked about.

no offense but your car can't be that fast. Something must be wrong. Otherwise everyone would lose prime when climbing steep grades. You have something going on in your tranny and your gonna blow it again deep pan or no. Take it back to the shop that rebuilt it and make them take a look.

I have heard that at high RPM the regular 10 Vane pump can't keep up and if you are going to run High RPM's alot to use the aftermarket 13 vane pump.
I am by no means a tranny GURU but have been doing a little research as i just bought a 700R4 for a 100$ in hopes that i can rebuild it to take the punishment that your dishing out with your 400 SB.
You have achieved what i hope to in the future.

Red73,
That is the most sanitary undercarriage I've ever seen on a Vette. :thumbs:
Do you ever have oil leaks?
I don't have major oil leaks....but little ones that dirty up the underside of my car everytime I nail it.....I think it's coming out from around the valve cover breathers.
