I ask because I have a 700r4 that been complketly rebuilt with shift kit, extra clutches stiffer spring kevlar belt, and I have a 2800 stall vigilate converter on it . Im looking for a complete drop in motor and really like the LS cevy motors.Thanks I have also been looking at the motors here:

I know a guy who was going to use a Turbo 350 behind a 5.3 LSx based engine, he had to buy an adapter plate so the old flexplate would bolt to the crank, but after doing all of that he went ahead and put a 4L60E in it instead. He was told by a couple of people that it wasn't worth the hassle to try and get the tranny to work with the engine. Plus the way the TV cable goes on a 700R4 there isn't a lug on the TB to hook it to so it would work properly, this was another thing he ran into as well.

 

700r4 and a 4l60e are the same exact transmissions. the only difference is the 4l60e is computer controlled. so yes 700r4 will bolt up. the only thing is one bolt whole wont line up.

 

NO....NO....NO The LSX 4l60e is different from the 700r4. the LSX 4l60e has a 2-piece bellhousing and a different torque converter.

 

dude my friend just bolted up a 700r4 straight up to his ls1 and only one bolt didnt line up.

 

OK

 

IT WILL BOLT UP FINE....
THE BELLHOUSING BOLT PATTERN IS THE SAME BUT IT'S NOT GOING TO RUN.

YOU HAVE TO USE A LSX FLYWHEEL, A CRANKSHAFT SPACER AND A NON-LSX TORQUE CONVERTER....

 

well i dont know what he did for the converter other then it has a 3500 stall. but i was only talking about it bolting up. and being the same dimentions. lol sorry to be confussing.

 

will take a bit of electronics on top of it to make everything work correctly (reverse lights, neutral safety switch, speedometer) but it can be done. my former boss is running a 700R4 on his car. He removed the TB and welded another ear to it with a place for the TV cable to snap on. The work itself is easy, just time consuming more than anything.

 

Lets ask Knyghtmare, he has done it!!

It bolted right up except for the top bolt. The 700R4 doesnt match up and so I left it. Its not a problem at all, no need to worry. I have the addapter plate on the flexplate to use the 700R4 or an LT1 converter. The LS1 input shaft off the engine side of the LS1 TC's are longer than the older LT1 TC's which are bassed more on the SBC than the Gen III engines. You only really need the adapter if your 700R4 is 28 spline as the LT1 and LS1 4L60E's are all 30. I did not use my TV cable as it was too much of a hastle for this setup being temporary. I havent had a problem with not using my TV cable, but I <b>do not recommend</b> not using it. In my opinion and experience with the 700R4, its not worth it as I am getting ride of the 700R4 and going with the 4L60E that im building. SO much better for the motor and you can tune it with the car. I only used the 700 so I could get the car driveable while I build the 4L60E.

My suggestion would be to sell or trade that 700R4 for a built 4L60E.

youre not using a tv cable?

 

Nope, and I havent had a problem with it. Its laying there across the top of the motor, but its not long enough because the car used to be TBI. I also have a ratched shifter though, so its easy to down shift manually, and a little more fun.

 

ok....

 

What?

 

nothing man, youre happy with it...

ive only taken 4 automatic transmission classes and have my certificate in automatic transmission building but if you say Fvck the tv cable then right on.

just to clarify, this is a 700r4 not a 4l60e correct?

the tv cable alows the trany to pressure up without it it would burn the clutchs up. or so i thought
but i say scrap the 700r for the 4l60e. the 700 is good but if your going to dog it all the time dont. i know ive been thourgh two built ones there good for crusin and some gettn on it

 

I didnt know that me not hooking up my TV cable was such a big deal to you. I'm sorry.

I dont need your resume, I didnt insult your intelligence nor was I asking for it. I wasnt telling anybody to ignore the TV cable, I just mentioned that for <b>my</b> setup, I did not require it. The 700R4 that I have in the car is temporary and just to get the car on the road. My 4L60E build up is a completely different setup.

The question was, is it possible to use the 700R4 in the swap and it is, I've done it. This thread isnt weather or not you should use your TV cable. My advice is that if your doing an LS1 swap and you want an A4, then go with the 4L60E.

You do with your TV cable what you want.

 

The physics of it are entirely possible; just don't forget the logistics of connecting and how critical the TV cable is though

Variance in line pressure from what the tranny needs vs. what it gets will destroy it.

 

education is priceless. read what tpiroc posted.

joe highschool comes long and spends his hard earned money on his swap, reads your post and thinks its ok to leave the tv cable off. the tv cable is difficult to set up so he figures if this guy is ok with it then its cool. 4 months later the transmission has gone to crap. now hes stuck and has no money to get it fixed.

just be aware of how important it is, and dont be so quick to so its a ok to not use the tv cable.

 

Your right, and I understand. I just hope that the people that read what I said realise that my setup is going to change and that I recommend a 4L60E anyway. If your going to go with a 700R4 then its possible, and...

Hook up your TV cable kids!!
