Thanks.. 8)I don't know what year they came out with the electric speed sensor, but the one I built for my Nova is a 91 and it has the electric speed sensor.
1988
The electric speed sensor has nothing to do with being a 4L60e. The "E" on the end means it is electronically shifted instead of hydraulic shifting. As long as it is a 700r4 or 4l60 it is the same transmission usually just called the 700r4. You can use a 4L60E in an older vehicle, but it requires a computer to be able to shift. If you get a 700r4 with the electric speedo setup you can change it over to cable driven fairly easily if you have to. There will be an electric plug where the driven gear sleeve normally is if it is an electric speedo setup.Exactly!.. Wonder if you can make it full manual just like the 4l80E, haven't heard anyone doing that yet??..
The 700 was a POS when it came out, every year as the complaints came in the factory upgraded it until 87 that was the last upgrade that's why the preferred unit is 87 on up, but if you can pick up an early core for a good price it's not a big deal to upgrade it to the later unit, then there's even more upgrades to make it even stronger. Only difference in the "E" is the valve body, oh and some of the later ones had electric speedometer drive.
What year did they start using computers to shift the trans? And what locks and unlocks the converter before computers?
The 4l60 is the upgraded version of the 700r4. The 4l60e is the electronic controlled shift version of the 4l60the 4l60e was out in 93 but i think it was only in the trucks post 93 and pre computers torque converter clutch (TCC) lockup function was actuated hydraulically at a set pressure without computer input this was the 83-87 700r4 afaik you cant run a toggle to the tcc on these transmissions because they are hydraulic not electric like the 4l60. you can only run the toggle to the 4l60 which is 87-93. the 4l60e is computer shifted so no bypass, are you seeing why i am saying 4l60 instead of 700r4? this is cause they arnt "the same transmission" they may look similar but most sb look similar. most people look similar but like we all were raised on you cant judge a book by its cover
you cant take a 4l60 rebuild kit and try to use it in a pre-87 700r4. they would have a "universal" kit if this was true. i mean who would want to rebuild a crappy trans with crappy parts if you can just throw the 4l60 parts in and be done. now you can retro-fit the newer parts (4l60) to fit the 700r4 but this is costly and its cheaper just to get a 4l60.

wow what you said is really different from what i said. that plug is off a 4l60 right? what i was saying is you cant just run a toggel switch to the 700r4 and think it will work without retrofitting something. but by time you retrofit everything you can you should of just got a 4l60You don't understand both trannys are the same, the lockup works the same on both, it's just a solenoid one wire to positive the other to ground with a toggle switch on one wire on/off, if you want it to work automatically leave it hooked up to the pressure switches on the VB, there's no retrofitting anything the lockup is a separate deal.
Soo, what you're saying is you could take two TH400's and put a shift kit, 32 element sprag, add clutches and heavy duty input shaft in one and that makes it two different transmissions.. :Dto this yes because they arnt built the same may have the same shell, but different personaltys if you would. they will handle power different, the way they shift and how much they can handle. its like saying a c10 and k30 are the same type of truck. since they both have the same shell but they where build for 2 total different reasons.
As far as the lockup goes that solenoid is there in all of them, now as far as not using the wires on newer ones is true but there's two sides to that story also and I admit I don't understand that one(not yet anyways)but my 91 has the plug in the case which I'm using with only the two wires directly from the solenoid, nothing hooked up to the VB..see and i didnt know it was just a simple as running a toggle switch to the 700r4s'.

see and i didnt know it was just a simple as running a toggle switch to the 700r4s'.I believe that was mentioned a couple of times, LOL..
but for argument sakeWell, I sure ain't no professional but we already know this stuff, and I guess somebody really screwed up when they made this diagram, LOL, but seems like you have it all figured out..(http://www.performanceboats.com/images/smilies/biggrin.gif) (http://www.performanceboats.com/images/smilies/action-smiley-069.gif)
lets leave this to the professionals lol

maybe after you read this you can clear up somethings with me also 8)
