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 4l60
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. 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
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 4l60
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..
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..
to 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.
see and i didnt know it was just a simple as running a toggle switch to the 700r4s'.
but for argument sake lets leave this to the professionals lolhttp://www.hotrod.com/techarticles/113_0704_700_r4_transmission/viewall.htmlmaybe after you read this you can clear up somethings with me also
