Re: 700R4 Failure

To say that a 700R4 is not a strong transmission is like saying that a chevy 350 is not a strong motor. You can buils a chevy 350 motor to make 150 HP or 600+HP . A stock 700 should handle 300-400 HP when installed correctly. On most stock 700 models the stock 3rd and 4th gears are the week point. I used the ceramic disk pack for these gears. The kit that I purchased had additional disks as well. This ceramic pack with extra friction disks makes a much stronger transmission. I also purchased a non electronic converter $99 at the local Daco Trans supply shop.

You also need to purchase the correct TV cable bracket that bolts to your carb.- i bought mine at Summit. ($40-50) thats the only way to adjust the shift properly. you will burn it up otherwise. if you are staying electronic lock up you need to buy a converter for that as well.

There is also a 28 spline and a 30 spline 700R4. i belive the smaller one was used on the V6 GM cars. I have been told that you can build this Transmission to handle Higher HP too.

Keep the 700- you will love the 4th gear when you are cruising at 70 and turning 2200 RPMs. I would not have anything else.
