QUESTION 1   QUESTION 2

Hi Mike,

I'm running a T-400 behind a blown BBC 427 drag car. I've got a Mike's 5500 stall converter and a Cheeta manual valve body. Everything works fine, but after a run I can drain fluid out of my overflow catch bottle. It's mounted on the rear firewall as high as I can get it. If I make three runs and don't drain it, it's full! What's up with that?

I am building a pro fwd car for the NHRA summit import series and I would like to get some input from you. I started the project one year ago and am nearing completion. Here's my setup: I have a Honda Civic with the newer s2000 Honda engine turbocharged with nitrous. It will be making 1000 wheel horse and weighing 1750 lbs. Brett at Mark Williams and I developed the motor plate from the Honda engine to a powerglide ... to a cassale V-drive with three percent overdrive ... to a Ford 9" thirdmember with 4.71 rear gear that is also located in the motor plate. TCI built a 7" converter with four percent slip and 7400 stall. The trans is new to me. With this much stall and redline of 9900, do you think the stock case will hold or do I go Dedenbear or ultra case? It will be using pro tree brake and is a shorty, and I am not sure what they did for torque multiplication. How do you find out? I am sorry if I sound lost, but I am new to this trans. Looking for reliability and breaking records, shooting for first fwd seven seconds. Everywhere I look, you come up. Just hoping I am going the right direction. Thanks for any input.

Gordon,

Fluid level on the 400 is a very shaky situation. Two things can contribute to this problem: A. Fluid level is too high, when trans is warm, the fluid level should be pan gasket level to 1/4" above. Any higher than that, the trans will breathe fluid out. B. Internal pressure leakage in sealing rings, valve body or pump halves, etc. Gordon, if it is just a little over full it will push fluid out when it gets warm.

Thanks,
Mike

 

 

Brent,

This setup sounds very cool. We have many specialized components for the Powerglide transmissions: billet input shafts, aluminum drums, spur gears sets, Dedenbear cases, etc. It would be a very good idea to use a Dedenbear case for a lot of reasons. One is the fact that all the S.F.I. shields are incorporated into the case design. Great for cars with limited tunnel clearance!

What you may find with this setup is the stall speed may not need to be as loose as you would think. The torque converter probably multiplies at a 2 to 1 ratio. What we have found is that the trans brakes and the turbo chargers are good buddies. This car should thunder!

Thanks,
Mike
