: 700r4: Mods needed for 3rd gear lock-up brimac Oct 28th, 06, 8:31 PM Done a search, but "I still haven't found, what I'm looking for". Are there any "in pan" valve body "changes" needed, (wiring, additional pressure switch/location etc.), .... for adding 3rd gear lock-up option, to a 700r4. Or, will converter lock-up anytime, I activate the existing solenoid circuit? Thanks ________ Brian chevguy65 Oct 28th, 06, 8:39 PM check out this link.... http://www.purplesagetradingpost.com/sumner/techinfo/700R4p4.html Hope its what your looking for, but why do you want a lockup in 3rd? brimac Oct 28th, 06, 8:51 PM Reason: 2500 stall at the moment, with 3.42's. Seems like crusin at 40-50, mph, for any length of time, ... could be "nicer", if locked up. edsatserv Oct 28th, 06, 10:52 PM ok if you want to have third gear lockup in a 700 trans it will depend on what year the 700 is as to what you have to do.. if you can tell me if its 82-86 or 87 & up. i can help get you there. brimac Oct 29th, 06, 1:41 AM ok if you want to have third gear lockup in a 700 trans it will depend on what year the 700 is as to what you have to do.. if you can tell me if its 82-86 or 87 & up. i can help get you there. edsatserv: Trans id code is... 9TU4243. It's a street/strip version, so it has some upgrades. Builder is out of business, ..or I'd be checking with them first. Thanks. _______ Brian onovakind67 Oct 29th, 06, 2:05 AM Done a search, but "I still haven't found, what I'm looking for".

Basically all you have to do is bring the wire for the lockup solenoid directly to the bulkhead plug and eliminate all the other switches inside the tranny. It will lock up anytime you energize the solenoid. | ||
