Had enough with my POS 700r4!

Hey guys,
As the title states I am fed up with my 700R4. I should say 700R4's!

I built a 57 Chevy p/u with a modest 350hp 350. I had an early stock 700r4 and smoked it soon after I got the truck on the road.

I then shelled out some major bucks for a 700 Raptor. This was great until that went belly up. I had a local guy rebuild it. I can tell by driving it that I have to majorlly baby it.

I'd really like to have some fun with my truck and not blow transmissions yearly.

I am thinking of swapping in a TH350. Other than the actual transmission, what else would I need to do?

Thanks.

Just making a guess, but how do you set your TV cable?

As Vince asked....and a PROPERLY built 700R4 will handle quite a bit of hp. Its just like an engine, ifin it ain't built right it won't run right.

A 700R4 Raptor is a properly built trans. TV cable adjustment, that could be a different story.

Yep improper TV adjustment can fry a trans quicker than the federal government can make a deduction from your paycheck. I don't care who built it.

Should you decide to go through w/the swap, the info HERE should be of some use to you.

In the meantime, I would suggest you double check the TV cable adjustment/operation. There are several tutorials online for setting it up correctly depending on the carb/induction set-up, so let us know if you need them.

I cant recall how I have the TV cable set. I have read a few things on it. I would like to read what you are talking about. It would suck if it I fried my own trans. But, it wouldnt be the 1st time I screwed something up.

The exact set-up depends on the carb or throttle body, etc. that you're using.

Look through the following links to find something that's relevant, or hit up google.

Generic linkage angle/travel requirements:

You sir, are the man. I have had the 700 behind a few different set ups. The 1st being a Rotchester 3x2 with the lokar bracket. Now it is on a Holley 570. I think I better find a really good shop and have them dial my tranny. my faith is slowly being restored.

The 700R4 is a great transmission when it is not behind a 800+ HP engine. The TV cable adjustment is probably the most important aspect of making a 700R4 live a long life. I see several cars at every rod get together with 700R4's where the TV cable has slack in it at idle. Do these people not read up on this stuff?

There're many who don't. Many think it's a Detent cable & don't bother adjusting/installing. I know several that have installed 2004R & 700R4 Trans without connecting the TV cable. The big problem is many builders remove the TV safety feature, "the TV exhaust ball & linkage". This prevents low pressure operation if the Cable breaks or becomes loose. ATSG Manual even recommends the checkball be omitted. Crazy to me.

As has been previously stated, the 700R4 is an excellent transmission. I use one behind my 460HP 383 and have been driving(beating) it for six years now. It's most important that the TV cable be properly set with these transmissions. If not properly set, the 700R4 will cease to work properly after as little as a couple miles.

I learned this the hard way as well with my first 700R4. While installing it, I disconnected the TV cable to make room for running the wiring for my lock up converter. Once my lock up was wired, I hopped in and drove from the shop to my house, approximately 10 miles. The next morning I pulled that tranny out, had it rebuilt(stock), and reinstalled that night. Been going strong ever since that day and I love how my car performs.
