Hey everyone, I'm replacing the turbo 350 in my '79 silverado with a 700R4 and I'm curious about the lockup torque converter. What does it do and what's the best way to go about hooking it up? Dustin
curious Several places offer lock-up kits, priced about $100.00 or so, you can order through Jegs, Summit, jagsthatrun, etc. Cheap way out is a toggle switch, but you have to rember to unlock and loc
Most 700's can be hooked up with 12 volts right to the pin from a switched power supply. Those kits are not needed for all but a few 700's. You can make it lock up in 2nd, 3rd and 4th or 3rd and 4th
I forgot to mention, the function of the lock up converter is for increased mileage. With no slip in the torque converter there is less heat build up and heat is wasted energy. So, more energy goes t
My 700R4 has not electronics, only the extra "ball" inside. Not sure where the ball was installed (rebuilder did that). After I installed the tranny behind my 261, I trailered it to his shop and he s
One of the list members (who it was escapes me presently) sent the following link a while ago. I though it was good reading on the 700R4: http://205.178.174.23/sumner/techinfo/700R4p1.html Regards, G
The 700 can be an electronic or non electronic. The electronic controlled ones are my favorite. Doing away with the electronics is a bad mistake. The computer controlled 700's shift so nice. The ball
I run a non-lock up converter in my '73 Chev 4 x 4. It's a custom build (very beefy build compared to the lock up converters I've seen - but I guess it would have to be) and has worked fine with the
All I was saying about those who run non lockup 700's is they are not getting what they paid for.. You can get varying stall speeds and still have lockup for mileage. I converted my 82 diesel to a 40
It's not stock at all - I replaced the T350 with the 700R for the overdrive. First, the non-lock up setup eliminates the need for any transmission wiring harness on the '73. Second, I wanted the heav
There are lots of different stock torque converters with varying stall speeds. have you used a big block converter or a diesel? I'd be interested in everything you did to your 700. Did you build it?
thought i might add one note to the 700 saga my father and i restored his 1982 chevy c10 a few years ago we put one of the gm parts crate motors in it 350/345 hp changed rear end from 2.73 single tra
On my 700, I wired it to go into lockup as soon as it goes into 4th. I also ran a wire straight out that will lock it in 2, 3, or 4 when power is applied. Both of these go to a switch on the dash. Th
As far as my Subs go, I'm going to use a 3speed +OD in the Chevy and a Hydramatic in the GMC, but I've been following this thread with interest; I'd kindof like to put an L98/700R4 in my 86 pickup if
I also forgot to mention that the Painless and TCI kits come with a low vacuum switch that cuts out the torque converter under acceleration or all-out foot to the floor. This is the way GM hooked it
