RE: [Chevelle-list] lock up, 200R4 success stories?

[Dave Studly]

Modern automatic transmissions usually have a “lock-up” torque converter.  Essentially, inside the torque converter, there is a physical clutch that will lock the crank to the input shaft of the trans, just like in a manual transmission.  The goal is to eliminate the slippage in the torque converter at cruising speeds.  Usually the RPM will drop by a couple hundred when it locks up.  It also doesn’t put all that heat into the trans fluid from the churning inside the converter.  Don’t quote me on that last part, though.   -Dave       -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, July 30, 2003 7:14 PM To: [EMAIL PROTECTED] Subject: Re: [Chevelle-list] 200R4 success stories? was: Trans cooler   Wayne, I guess yah just gotta drive faster then huh? lol haha just kidding! :o) But I do have a question to everyone...what does it mean to be "locked up"? -Tim- 1966 Chevelle
