Is this a kickdown issue?

Hmmm the 200R4 ratios do look good. Not that I race the car, but can they stand up to a 440? With a 28" tall tire, I'd probably settle for a  gear in the 3.7 range. Fun in town and good ln long drives.

Extreme automatics has them in 3 different stages. You can pick whichever suites your application and/or pocketbook. I think their best unit is rated 1000hp/750tq. They have good reviews too. I'm planning on going with their middle rated unit for my 72 chevelle with a 383 sbc.

Oh gotcha. If I spend that kind of money I'd get a manual though. I may just get a stock 200R4 just for cruising around town in the meantime. The gear ratios do look better than the 700R4.

I think the wide 1-2 gear spread in the 700R4 isn't the big issue it's made out to be. I've had two of them and, in normal driving, you don't notice it and at WOT 1-2 upshifts there's no noticeable bog if you have a modicum of horsepower. The deep 1st gear allows a lower numeric axle ratio without sacrificing the launch.

Same with the wide-ratio standard transmissions, the only time it's an issue is if your road racing and don't want a big rpm drop when shifting a lot.

The 700R4 and the electronic version 4L60E are decent transmissions.
I had one in my 76 Camaro and my 84 Chevy C-10. Those two had mild engines so the gear spread wasn't an issue.
The manual transmissions with a wide spread like the 833 OD are a different matter.
3.09 to a 1.67 is a huge drop for a manual. I had one in a Duster with a 360 I built with a bit bigger cam. The ratio spread was not good. It felt like shifting from 1st to 3rd.

I installed the 764 torque converter and oh boy what a disappointment. Now it really has trouble moving. The prior TC gave me a brake stall of 1700-1800, this new one only 1300. I don't know how it could be this low, but it's a real dog to drive.

Man that's not right that spec was 2100-2400 stall. Should have been perfect for your build?

[John_Kunkel]

On the stall speed chart I posted on page 1, the 340-4 and 383-4 are the 764 converter.

[Dino]

That's what I thought. I don't know what's going on.

[b5blue]

It could be a crap rebuild. (Like many A-1 Cardone parts.) 

[Dino]

Yeah I guess so. I'll have to by yet another one. Maybe the cam timing isn't right either. I don't know. Compression is vetween 160 and 170 on all cylinders so that's good.

This black TC is supposedly 2500-2800 stall, but the seller can only dind 3303 stamped on it and I can't find any info on it.

Good Luck Derk!
