Thread: 700R4 "Lock up" Torque converter

Tweet

Well it took me almost a year to get mine all set up and working But I am a slow old guy.

I have the 700 behind a BBC. There is no more need for switches. There is now a hyd lock up for 4th gear thats in the valve body. Cost about 150 extra depending on who you get the tranny from. It can also be setup to lockup at the MPH (or close) to what you want. I wanted mine as low as it would go. It locks up about 38 MPH and I love it compared to the th400. I can now pass a gas station.

Search around. I can't really recomend a trans shop because I had almost a years worth of trouble. I also have a lock up spare valve body because they thought that was the problem why mine wouldn't lock up. Turned out to be the governor. The valve body is for sale 150 + shipping because that's what it cost me to have it replaced. I know it works because it would lock up and then unlock off and on. The governor was the problem. There were burrs on the outter flapper that the inner flapper got stuck on. Of course you don't know this in the car. In hand I found the problem. Actually a file could have fixed it but they sent me a new one so I used it.

I am very satisfied with the 700. Don't know about the strip. Broke the first one on the 3rd run. Second one has held up with about 20 runs. Well see.

I am running a 3600 flash stall, 3200 on foot brake. Works excellent on the street. Proly could use a little more for the strip.

Give these guys a call, they have a hydraulic lockup version.

Paradise,

My setup is just sitting in the garage waiting for installation of the radiator and electrical stuff so I have not run my Monster 700R4 yet but I got the one with the hydraulic lockup. You say you resell the MM units but then mention a one-wire lockup. Can you compare the electrical lockup with the hydraulic lockup version? With the electrical lockup it seems to me that you have to hit the brakes to get a downshift? I liked the idea of the hydraulic lockup so that if I encounter a steep hill in OD I should get an automatic downshift?
