I have a stock 200-4R and I'm running computer delete but I'd still like to have torque converter lockup for highway cruising. This Monster Transmissions kit seems simple enough:

Any opinions on this, or anything I should know before I spend the hundred bucks? Thanks guys

If you want to save some money and electrically inclined, I squirreled away the sensor number that can be used to put the kit together yourself. Buy the switch of your choice and a fuse holder (if you don’t already have them) . You could get the 1/8” NPT 90-degree fitting and some wiring (if you don’t already have it) at your local hardware store. You could use the Monster video and the diagram on their site for the wiring. It takes less than $30 worth of parts to do it yourself.

Normally Open Oil Pressure Switch - $12 at Napa (don't know the cross-reference for other brands)

Eaton Fitting - $2.14 at Amazon (should be about that at the local hardware store)

4 Pin Weather Pack Connector - $6 from eBay (it has the female ends and the pins (some sell the connector without the pins)

Switch of your choice – starting at $2 from Summit

The only thing I noticed missing from the Monster kit is a brake interrupt so when you press the brakes it disengages lockup. I have the Bowler kit but it's twice the money and not worth it. It's a really simple system and I think BadSS has a great solution - you may want to incorporate tying it into the brake pedal switch to complete the circuit.

This is some great info, thanks for taking the time to type all this out! That's probably what I'll do.

Could I expect driveability issues without a brake interrupt? Like will it stall when I stop? I assumed the lockup would disengage when the transmission shifts out of 4th

Brake interrupt would be a benefit.
The reason being if you forget to turn off the switch when out of 4th gear or accelerating after slowing down and not in 4th gear.

Having that switch p/n is valuable information, thanks for passing it along.

I've used very similar kits and used the cruise control brake interrupt switch to power them. This allows the stalk mounted cruise control switch to turn power on/off to the circuit, and incorporates a brake pedal switch into the circuit as well.

My only issue with this style of wiring/circuit is the converter locks immediately and always when the transmission is in 4th gear. I'm spoiled with the stock ecm's ability allow 4th gear operation with the converter unlocked in situations like high load and low coolant temp.
