considering no one has EVER mentioned how well ANY shift or rebuild kit has worked for these autos and basically no specialty shops want to touch them, you're pretty guaranteed you won't get the results you're looking for without reworking the whole transmission and not just a basic rebuilt or light modifications.

these autos are junk. there's good reason why 98% of the cars that rolled off the delivery truck came with manuals, because the auto that was installed was just a placebo for people who really wanted a RX7 and can't drive stick.

For what it's worth, good luck. I suspect the results will be underwhelming but give it a shot.

I guess I could reiterate by saying I hope it makes a big difference.

I spoke with level 10 and they make both an upgraded valve body, and torque converter. They are way more expensive than I'm willin to spend. Though I would venture to say the valve body upgrade is likely just modified with the shift kit.

a better alternative would be a turbo 350, a hammer to the tunnel and an adapter plate. much simpler to modify, an abundance of parts and a much more stout transmission that can slam the gears as hard as you want and won't hurt the burly transmission made for a much heavier car.

if i were to make a drag specific car that is probably what i would do, as the GM manuals are a bit more costly to swap in and air shifter trannies even more costly yet again. downside compared to manual trannies is drivetrain horsepower loss % where you will minimally lose out with a manual.

1. Why would you want an auto rx7?
2. I forgot what I was going to say haha

I just swapped in another auto tranny (lost 2nd gear) that was supposed to be rebuilt. So much work and new tranny has no 2nd gear either. WTF! Doesn't matter how sloppy these trannies are I just wished they effin worked! They suck! Good day.

where do you find such an adapter plate??
