Curt in Curt's Corner goes over how to convert a factory lock up circuit to a 4th gear lock up on a 700R4 Transmission.
This does involve adapting the wiring harness in a way that can not be undone. Proceed with caution and if you are an inexperienced mechanic consider having a professional do this for you.

You are the true MVP I understood as to what the 4th gear pressure tap was and temperature switch is but you definitely explain how to hardwire it up better than what Superior Solutions schematic what's showing it was like it was written up by a kindergartener
A little tip on installing the pan with the gasket, put a bolt in each corner through both pan and gasket. The gasket should hold the bolts in place and keep the gasket in place so it doesn't flop around on you.
What does doing this do ?What are the benefits of doing this ?
Thank you so much for that great info💯💯💯👍👍👍
So to get this to lock up all you need to do is rewire change the pressure switch and have one power wire to the trans from a keyed fused source?
Yes, we also have a 700R4 Lock Up Kit will have everything needed for that. You can find it here:

I have this exact trany and will be installing this internal two prong pressure switch. My question is how do I connect the four prong external conector to the switch ? as this was not mentioned in this video specifically.
That is because you're only going to be using the positive and negative wires, the others are deleted.
So I bought a 91 S10 with 4.3 and 700r4, I think I am having shudder, worse in the mornings when cold, will this kit fix that?
No this is for conversions I would check tv adjustment and fluid levels
So basically we don’t even need the switch? Or (On the driver side connector do I run the run positive wire up to the switch / have other negative grounded to tranny? Or can we run the negative directly to the negative part on switch? Help… thanks
No you don't need a switch up top but if you are going up or down hills or hauling a trailer or something super heavy it would help you a lot to have so you don't put too much stress on and lugg out the motor. And yes you can run direct negative to switch.
In doing this, whats the best way to install a temp gauge on this trans?
Hw can I add a temperature gauge to my 700R4 transmission on my 1984 K20 Chevy Suburban; 4wd????
700rr on my 89 Chevy z71 lost 3rd gear and overdrive seems to work at a high rpm what's the problem
It sounds like your 3-4 clutch pack is burnt.
Is this procedure apply to the 200r4 as well?
Part number of pressure switch? Quick link to it? Please.
We don't have this part on our site, sorry Ryan. But if you give us a call at 800-708-0087 we can get that part for you.

will it unlock by its self as i down shift
And will the converter lock up instantly as soon as the trans shifts to fourth or is in a slight delay
In delay until line pressure satisfies the pressure switch
Why not use the temp switch? Is it not important to have warm fluid?
The temp switch only works for the oem system without a exm to control signal it has to be an on/off system
So I still plug in the white plug that’s on the outside of the transmission that’s on the driver side ? It’s like a 3-4 white prong plug
Yes sir. The lock up solenoid needs the power.
I need to know if about a governor on a 700 R4

I'm looking for a kit that locks up on its on without me having to turn a switch off and on
Hello! We can help you with this give our team a call at 800-708-0087.
can anyone help me figure out how to wire the new pan connecter outside the tranny?
Our tech information section will walk you through this process: www.monstertransmission.com/Tech-Guides_c_8066.html
Must a lock up converter be jused after this mod., or just a standart converter like in a TH400 ?
Yes you would need to use a lock up converter on a 700R4, unless you convert it to a non lock up unit.
How much is the kit, and could I buy it factory direct?
Here is a link to both options. One with the 4th Gear Pressure port and the other with out the 4th gear pressure port on the case. Thank you for choosing Monster Transmissions.

@@MonsterTransmission I'm not 100% which one is in a stock 1990 Corvette. Last question is would this lock up in 4th gear only?
Yours should have factory Lock up if no one got into it from 1990. Our 4th Gear Lock Up Kit is designed to only be engaged in 4th gear in cruising speeds so take advantage of that Fuel Economy. This is engaged with a Switch we recommend to only turn the switch on when in 4th gear typically cruising around 55mph is the average and when you slow down out of 4th gear you would turn off the switch to ensure you don't burn up the Lock Up Solenoid in the Transmission.
@@MonsterTransmission It wants to lock up a 45 mph which is way to slow of a speed to lock up in 4th gear. I understand is great for gas mileage, but it's a Corvette, and performance should be first. It would be great to lock up in 4th any above 60 mph.
This kit is designed on the switch so you can activate it when you want and you will need to turn the switch off when you come out of 4th gear below 55 mph yourself to ensure not to burn up the Lock up Solenoid in the Transmission. So if you want it to come in after 45 mph then do not flip the switch until that preferred time. Thank you for choosing Monster Transmissions.
How do it come out of lock up
When it down shifts to 3rd, it opens the pressure switch and turns off the TCC solenoid.
Monster Transmission ok thanks
No problem!
Ok
