Post Need help adjusting 700r4 tv cable

this morning i just finished installing my 700r4 with a shift kit in my 84 monte carlo.

I took out for a test drive and felt it a little lazy, i then noticed it threw in 2nd gear right away.

before it wouldnt do this. I was told that i just need to adjust the tv cable. Thats the problem i dont know how.

This is one adjustment that MUST be done correctly or you will toast your 700 pretty quickly. Here is probably your problem. Most of the books say to rotate the throttle lever at the trottle body. This takes the ratchet too far and causes the soft/early shift problem you have.

Instead, (engine off) release the TV (hold down the metal readjust tab at the engine end of the cable), move the slider until it stops against the fitting, then release the readjust tab. Now (most important) get in the car and press the accelerator to the floor to set the cable. Check that the cable moves freely. Now go for a short road test. The tranny should shift right now. I can't remember the exact mph, but it should be later and firmer (more is better here).

Soft, early shifts with a 700r heat them up fast and they will not last (experience taught me this). Hope this helps.

I had a 92 silverado that the dealer had just put in a new torque converter before I bought it. (No warranty of course). It was a crysler dealer and they must have used Haynes/Chiltons and followed their directions. I drove it about 2 weeks before the tranny overheated, blew the front seal and dumped all the red stuff on the interstate.
I installed a rebuilt in my 92 silverado and put another 60,000 miles on it without problems following these instructions from the rebuilder.

I'll try to find the instructions with the shift points... no guarantees, that was 6 years ago.

Good luck.

I am also having difficulty adjusting my TV cable for my 700R4. Although with the current adjustment it seems to be shifting (and downshifting) more as I would expect it to (I have no prior experience with a 700R4), it still shifts out of first and into second even though the gear selector is firmly in the "first" position. This happens if the the car accelerated rapidly. If the gas pedal is pushed slightly forward while the tranny is in first, the RPMs will climb but the tranny doesn't shift out of first. I used to have the "stock style" TV cable with the ratchet head but switched to the Lokar style which doesn't have the same type of two way adjustment flexibility of the stock style.

My first question is: Will a 700R4 shift out of first even with the gear selector left in first? Second question is: Is it possible to properly adjust the TV cable using the Lokar set-up rather than the stock set-up?

I am running a hot 350 SBC in a 57 Chevy, fresh 700R4 with shift kit and non lock up converter, 3.73 10 Bolt with Eaton posi.

Thanks,
Keppie

I couldn't find the old sheet that had the shift points on it, but I did find a site for the place I got the tranny and the instructions:

<a href="http://donneysaab.com/fdt/fdtretail.htm" target="_blank">http://donneysaab.com/fdt/fdtretail.htm</a>
email them at:
tech@fdtrans.com
Phone: Nationwide Wats 800-622-4836

If you are still having trouble, check them out. I don't know how much info they will give out if you don't buy a trans. from them, but they were great when I got mine. They really know their stuff.

Hope your 700r stands up as well as mine did.

Dan,
Thanks much for your tip. I checked out the replies you got. It looks like it might be one of the 700R4s that shifts whether I want it to or not. Under full acceleration, it is not getting to 6000 where I want it to shift under WOT. So HMMMM. How do I find out if my tranny, definately not computer controlled is one of those that is set up to shift regardless of what I do??!!
