So far my Original question hasn't been answered I believe, or I am not understanding something.

I'll start over and ask it this way, I know this trans is a 700R4/4L60 and is Not a 4L60E hence the "E" being its electronically controlled meaning that trans would be in a car with a Computer "right" or will it work with just a switch and some wire? My 68 C10 has No Computer at all and never will so does it now need an After Market type product to have the OD hookup to work?

PS, I thought I was adding to my original thread, If you want to read it first it all will make sense. Its at "Another 700R4/4L60 lockup ?'s

All you need is the tcc wiring diagram, so what is the difference where it comes from. As I said there is plenty on the net.

First thing is you need to tell us is it a 700r 4 are a a 4L60, they are basicly the same but wiring is different.

The 700r4 can be used with no computer but you have to drop the pan and install a lockup wiring circuit for to lock up. B&M makes a simple one as does many others do now. You need the TV cable hooked up correctly also which is a crutial part in it working correctly.

4L60 Designation
The 4L60 designation, while the same for the 4L60 and 4L60E represents the fact the transmissions are four gears, Longitudinally positioned, The engine is capable of supporting a 6,000-lb Gross Vehicle Weight Rating (GVWR). The 4L60E transmission has proven to be stronger than then original 4L60 and is installed in applications up to 8,600-lb. GVWR.

The 4l60e is computer controlled but they make a stand alone that will work it in a non ECU vehicle.

NOO NNOO NO you don't need any aftermarket B.S. to run this trans.IF its the later trans 88-93 then just wire it in. look at Bowtie Overdrives and they have a diagram on there site. I don't wire mine into the brake switch and just use a toggle to lock it when I want.

Andy I am having trouble finding what it is from Local Trans shop & a local Dealer Chevy/GMC. The Trans shop says if it has a TV cable its a 700R4 but the dealer says both 700R4 & 4L60 has a cable. This dealer is doing further research on the suffix code (2FTM098H) & casting #'s (8676358) also the RPO code (MD8) and will get back with his answers.
The TV cable has been fixed with the proper parts, My Holley carb is a(1850-11/4160) 600cfm vac sec & is using genuine Holley parts (20-121)Geometry Corrector & the (20-95) TV Cable/Throttle bracket installed and adjusted. Throttle bracket is modified for Non Cable usage, stock throttle Rods are used.
I hope this additional info is what you need?

Maybe I am not understanding this. You said you can Lock it up any time you want in any gear? I thought the OD trans only lockup in 4th gear?
What is the wiring diagram method you use to lock it up? can you post a picture/drawing of it? I know 4 strikes (?) and you are out LOL LOL I hope not.
Thanks, Marvin

NO,NO,NO What?
I ran my 700R4 for 15 years and never had a problem. I wired it myself to lock in 4th gear only it's the only gear you need overdrive. You don't need any input from the motor all you need is 45 MPH speed and a power wire.
A brake switch would be a nice feature to make sure the convertor unlocks in a panic stop only.

The website states your transmission must have a working lock up circuit inside the pan before their kit will work.

Monster Sale Price: $99.00



I had the 700r4 in my truck since early 90's with no problems's.
When I did mine it didn't and the only way to know is for the pan to come off are try it and see if it works. I chose to do it before I installed it to keep from doing the work under the truck.

No,no!
Locking it up yourself isn't good. The transmission needs to unlock under 45 MPH and in a panic stop it may not. Ask me how I know. You also don't want it lugging in slower speeds and slipping. It will work but your playing a dangerous game doing it this way.
The computer does all this on a 4l60 and 60e.

How did you wire your trans? show it with a drawing/diagram picture please.

Easy now gent's I'm had a bad morning I have mine wired just like the diagram I posted, I use a rocker switch to lockup I lock it up at around the 50mph and unlock the same, you know its locked when you come to a stop. Yes the brake feature is a nice addition, I have been going to add one but never have. Seven years this way and no problems. All the late 700=4L60 came with the 3 letter code in them 2THC333 etc. as the earlier only had 2 =2TH333 etc. looks like yours is from an 02 truck.I am by no means a mech. or super knowledgeable person just my little bit of info I'M hoping someone can use or figure out what the he# # I'm trying to explain.

Nobody seems to want to believe this, but the factory setup allows the 700 (I'm not sure about the later versions) to lock up in any gear except 1st. The lockup is slow to disengage on its own as you come to a stop, so that's why you need a brake switch. Otherwise, the engine can "struggle", as some of you have already observed.

Those who choose an automatic transmission want transportation. Those who choose a manual transmission want to drive.

The 6.0 LS engine and ECU work just like they do in the 3500 it came out of.

The 700R4 was took out 4 years ago when I swapped in the 6.0.

The 700R4 was wired as the connections you showed but instead of a switch that I had to flip it was automatic locked at 45MPH are above.Yes the 700 would lock in any gear if you where over 45 MPH but the only one you really need it is 4th. No need for it in third how many people drive at 70-80 MPH in 3 gear! I hooked it up so when I put on the brakes it would turn the signal off to it and knocked the lockup off.
I installed the B&M wiring in the transmission when I did the 700R4 swap but no wiring diagram. That was a long time ago.

I believe you because my 700r4 in my 1983 G20 van would lock as low as 18-20 mph in 2nd gear. It had a vacuum switch connected to ported vacuum which let it unlock as soon as you lifted from the throttle. At least in my application having the brake switch was double redundant.

Here is another thread that nails it down,I cant see spending $100 for $20 worth of parts. There are several ways to hook it up to your liking
