That explains what I am feeling in my new GMC truck. I just didn't know exactly what I was feeling until reading this.

I think it is an actual clutch pack that when engaged basically bypasses converter making it a direct drive when engaged.

The dump valves remove some pressure on converter to LOOSEN it up to spool up quicker. Especially helpful on Turbos. Different deal.


The lock up converters have been on factory cars for a while big help in gas mileage. The advantage to us is full lock up when ever activated and acts almost like another gear.

Actually, its better than another gear, it is shift, or shifts with 0 slip.

I've noticed my 18' F150 with the 5.0 locks up in 3rd gear, and it does literally act as another gear change it seems. I'm curious to hear more on the advantages of locking it up later though in these trucks if anyone has some insight.. I've thought about having the truck tuned more or less for trans tuning cause it does feel clunky sometimes and not very smooth at certain throttle positions and speeds (and I'm not even referring to if on the pedal hard, just normal driving).

Only reason to not lock it up early is if you are in a HARD pull with more power than stock. The 68RFE in the 2500/3500 rams dont like making the 3-4 gear change with the converter locked, if you are pulling weight, with the truck turned up, AND having your foot deep into the throttle. Those transmissions will usually break hard parts doing that. The 6R140 and Alison doesnt seem to mind it, but ironically, the 6r140 has the shortest life expectancy of all 3 of those transmissions.

The sooner you lock the converter up, the more fuel efficiency you get, and the better they accelerate.

You have the 6r80, which uses same internal parts as the 6l80 in the GMs. The 6r80s typically last 50,000 miles longer. If you are starting to get some weird shifts occasionally, it is prolly time for a trans service. If you do decide to service the trans, you are better to let Ford do it. It is a royal pain to add fluid to that trans because it doesnt have a LONG dip stick. It has a nub where the dip stick should go. Also, if you do service it, go to Ford and buy the filter and fluid from them, Mercon LV is prolly one of the best trans fluids out there right now, It is prolly a close quality to Transynd. Next, when you are removing the filter, DO NOT PRY ON ANYTHING!!!!! To get the filter out, you will bust the lead frame on the computer, and then it will be screwed, and you will be going to a trans shop or Ford to get it fixed. To fix it, you have to replace computer, and re program it.

Makes sense, but I don't know how much different it is but my transmission is the 10 speed, which I believe is the 10R80..

They actually work and act much like the the 6r80, usually have same issues when they do come apart. If you service that transmission, no reason that trans should make 180/200,000 miles before a rebuild or replacement needs to be done.

That is what I'm thinking about.

Years back I was talking to a Top Sportsman guy and he told me they were using a 3 speed transmission that was actually over drive in high.
At the time I was under the impression that a 3 speed had to much low gear ratio. This was way before all the available low gear sets we have today. I was blown away by that info, thinking it would be hard to control the hit.

My reason for the initial post is thinking that maybe going into lock up at say 550' or so would make my car take off like hitting a scramble button and would be the opposite of spot dropping..lol

As I said earlier, watching Ryan Martin start around a guy in the other lane and suddenly his car takes off like a raped ape.. Got me thinking.. (Not about raping an ape..lol)

Depends on how the engine responds to the load. I highly doubt you would see any et gains, but should see some mph gain.

I've had a lock up for sometime.
To use it properly you really need to think about the whole system (i.e. gear ratios, boost, RPM, etc.
Mine locks up about 300 feet or so.

https://imgur.com/a/XeDLirk

I actually took it out because it was too fast for TD.
I've actually been 199 MPH in the eighth with it (166 @ 6.00 in quarter when I lifted because it was WAY fast).

LOL....1.11 to the 60 but damn near 200 to the 660, that is badass!!!

Do you have any run graphs you can share? I would love to see one.

Can you share details about how it works? How is it actuated? Did it negatively impact your 60' on that run?

Is it just me or has technology driven the cost of drag racing FAR beyond what the average Sportsman Racer can afford.

Take a transmission, converter and air/electric shifter that is approaching the $10,000 range.

Powered by engines and electronic systems now costing $40,000 + (Throttle Stop, Ignition, data recorder, etc. included).

Installed in a $150,000 + custom built chassis.

Towed IN a $60,000 + stacker.

Towed BY a $450,000 + motor home.

Add in the shop and equipment you need to store and maintain the car. Pick a number .

A race entry fee of $360.

And you are in the...... $710,360 range. I purposely did not include the shop at home plus the golf cart expense (where required)

So you can WHAT , try and win $1,800 ????

Is this pricing excessive, absolutely but not unusual. There are many folks out there willing and capable of spending that amount to compete for a $1,800 purse while given the privilege of parking in the dirt or pee gravel and treated like a third World citizen by a $10 - $15 an hour track worker.

If this seems a little insane maybe it's because, frankly, it IS insane.

What we spend on this sport would make most people think "We have lost out minds". All for the thrill of speed. Winning is extra. Win,lose or draw. If i ever had the the opportunity to add all the receipts from when i started in 1974. I should be in a padded cell. That doesn't include the Kart racing days. That was another adventure in a class all by itself.

Bottom line>> It is an addiction at it's extreme.I could not start to tell you just how many got divorced because of the addiction that
I hung out with. The marriage or the car.
