Subject: RE:Automatic Transmissions by bogus on 2006/2/19 22:00:20 some clarification: The 700R4 and 4L60 are essentially the same unit. There are some changes, but not significant. The 4L60E started in 1994. The 4L60 started in 1992. But as I said, the 4L60 is just a name change... As for your needs, the 700R4 is fine. Now, lockup... you may want to get more detail from Pete, cause I am not all that clear on the concept myself, but, in short, the torque converter is a pump and it accepts a lot of the driveline lash. You can look at a TC as a shock absorber. Now, when a TC locks up, it is acting much like a direct connection between the engine and the transmission. Until lockup occurs, it's a fluid connection. It causes slip in the driveline. |
