200-4R Upgrades and Tips?

[Reapersgbodys]

I've got a 700R4 in my 84 Grand Prix, the lock up controller of which you speak was accomplished with a toggle switch, I control when it goes into lock up, and the way this car is geared, I'm only pulling about 1700 RPM at 80 MPH, and gets awesome highway mileage.

Throw it in the scrap pile and install a 4L80

I vote for 9 second power and 3.08 gears with a th400.

I bought a CZ unit out of a Monte Carlo SS for my Small block Corvette. He said he wasnt happy with the shifting and sold it for $100.

I put it in as is and it had a 3rd gear flare. (my car only has about 325hp)

I put in a CK Performance recalibration kit and his competition servo. Granted this is a weekend car but between the servo and the increased pressure of the kit, it hasnt had a problem since. I bought a spare trans to rebuild as a spare but haven't needed to worry about it.

That said, you might check the size of the servo and mic the boost valve too to see what you have.

Which CK servo did you buy? I noticed they have a couple different ones. Thanks for the input.
