You helped me understand the changes in stall speed I experienced. 69 Nova. As weight decreased, so did stall speed. As power increased, so did stall speed.
That was a perfect video, the right amount of information. Love your work and keep it up.
Much appreciated!
Thank you for sharing & breaking it down for us. I’m at the point in life where I now need a transmission rebuild for my 94 Chevy impala SS. I’m obsessed with learning about a critical part to our cars. Jus subscribed 🇺🇸
Great video! Good for you for putting people straight!
Good to see you back on utube
Thanks for your time. Shitload of solid information in here. You're hard on yourself. I like that. 👍Good stuff.
Thank you,this was most of what I was looking for.I’ve been all over you/tube looking but they all act like this is a state secret.I would cation anyone shopping for converters/advise to make sure they listen to you,I had a big co.build one and didn’t come close bc they didn’t listen.good stuff,thanks,oh I was busy with something else the first time thru and missed it,for me
It no biggie, its a long video with a lot of info. glad it helped you.
This is all excellent information, thank you for putting this together! I'm a huge nerd for all the automotive math and specifications, but I gotta say the best piece of advice in the whole video... Pick up the phone and call. Have a real conversation. Thank you sir!
On side note i read every bit instructions i got with my transmission all went great still doing great 2 years later
Thats awesome to hear! Keep taking care of it, keeping it cool, and servicing it right and you will have many years to come!
@@PerformaBuiltTransmissions do my best to best 700r4 ive ever owned
Street stall at 2k range? Had a fbody with a 4l80 and bolt on ls1 and I went for a 5000 hard hit torque converter and I got the biggest trans cooler I could find and it was the best tc for street Ive ever experienced and Ive done a bunch of them different setups. The car actually did a wheelie at the track and was stupid fun on the street and super manageable for cruising and non wot driving
383 stroker in a C3 Corvette with th400 and 336 rear end with short tires (26.5" diameter). 100% street car. Had a 2600 stall and it was hard to get used to. Too much revs and noise at a stop light before going anywhere. Swapped to a 2200 and much happier.
Thank you! Amazing video! Currently planning a 408 build on a lq4, with a stage 2 Brian Tooley Torque Cam with the 4l80e in my 5500 lb 2006 1500HD Chevy Silverado. This video has done wonders in helping me figure this out. We are probably looking for that 450-500 trq range but won't actually know till it's dyno long after everything is in. Probably gonna go with a 2200-2400 or 2400-2600 stall speed.
Great Video! Have a 83 C10 getting LS Swapped with the FTI 3000 stall torque converter hope to have it back by C10 at the Brazos in Waco TX
Make sure you tune for that stall speed. And im not talking shift points.
Good video man. Last year we were building my wife's cruiser. We called you guys, spoke with Alan, I believe. Her car is a '63 Chevy II, 10.8:1 383, AFR 195 cnc heads, dual plane intake, Holley Stealth Sniper, 241/247 @ .050", .583/.565", 112lsa, 108cl hyd roller cam, 27" tires with a 3.89 rear gear. I'd guess curb weight is around 2900lbs. You guys built us a stg2 4L60, which we went through you guys to get a FTI 9.5" 2800-3000 stall converter. We ended up using USShift quick4 controller and have stuck with their 6000rpm wot shift programmed tune. It ended up making 386rwhp/369rwtq. It runs great for being a quick little street cruiser.
Este video es oro puro, vale la pena revisarlo una y otra vez para medio entender jeje almenos para aquellos q somos novatos como yo. Saludos!! Me encantaria saber qué convertidor usar para mi pontiac grand prix supercargado..
Mahalo! Excellent explanation.
great video
Great Vid. Lots of awesome info but does my on road and trail riding CJ7 5.3L need to worry about single disk or triple disk?
If your over 800hp or locking it up in other gears other than 4th and cruising, then you will need a triple disc. A single will handle 5 to 800 cruising 4th OD and Lockup.
well done
So I’m one of those ocd people that blue prints everything as I build it. Lots of math. Curious to see the rest of the calculations to get it all right.
I’m looking to ls swap a ranger with a with a 6.0 and a 4L80 with a 222/232 112lsa cam and 29 inch tires, ideally I’d like to run 4.56’s or 4.88’s to make up for the long 4L80 gears and a gear vendors to bring the highway rpm’s back down and split gears, would something like a 2600 stall be optimal for this situation?
It wouldnt be ideal for racing but for light street driving and towing it would be fine
What would be the best application for a 94 gmc c1500 extra cab with 4L60e transmission , stock 350 engine , 425 gear ratio , 4” suspension lift and 35”x20” tires and rims , it’s my daily driver and I tow construction material with it , I looking for smooth ride in the highway at I tow , please help?

At 11:00 in the morning I heard grab a beer so I did it's cracked
I’m changing from a th400 to a 2004r in my C3. I have a 3000 stall in it now. I like it but wondering if I should bump it up a bit for the 200. Like 3400. Street/strip .486/.500 cam, 107 LSA, 243/257 duration @.050, 4”hg, in drive,3.70 gears, 28” tires, 3” exhaust around 350 hp 31-3200 lbs
Changing the trans isnt going to affect your stall spd. The engine, rear, and tires are what affects your stall spd.
Quick question. I know you need more info. I have a 2700 stall which should be streetable in and just took it out today. It's a jegs brand and it would not really move without a lot of rpms. Could barely make it through a intersection driving it normal. Could it be a bad converter or just totally wrong?
If you floor it it goes. Thanks
You have a bad converter or something else wrong. Advice i would never ever ever buy any converter through a big outlet like summit and jegs brand. They just aren't good and the bottom of the barrel for even oem function. Pick a reputable company like fti or circle d for a solid build.
Do you have a 700R4 that will live behind a BBC torquey street engine? Have a TH400 currently in my 1972 C10 with 3.73 gears and is revving 3000+ RPM on the freeway at 70 mph. Really would like an OD for mpg’s and less revs.
700 isnt my first choice for an update and requires an exact tv cable setup at all times but yes we are able to build that. Please calls sales during buisness hours to spec one out or visit www.performabuilt.com to veiw our products
What’s a good stall for single cab truck with 5.3 & 212/218 .550/.550 112 LSA
Need way more information than that and i recommend consulting the converter company of your choice for the best results.
Does line pressure affect stall speed or flash stall ?
Have you done any videos on dumb valves ?
Very little effect and usually not enough to make a change. But it can ever so slightly. We require stock line pressure in all of our builds. I dont have a video on dumps but there are many out there on YT
#3050 Hobby stock 1:82 powerglide 500/500Lift 232/232Duration 108LSA. 2500-6800 rpm Range 3/8 tight asphalt circle track. What stall you recommend?? 3:73 rear gear 678 final drive
Thats great information and your well prepared! You have every number you need to sit down with some paper and plug them all into the K factor equation for a base stall speed! Then actual flash stall speed! You got this yourself! 🙌😃
6.0 block, LS3 heads , lsx 102 FAST intake manifold, 102 NW drive by wire throttle body, cam spec 239/251 624/624 113+2, i have a yank 3600 stall in a stock 4L65E. I am looking to rebuild or purchase a new transmission for my 2005 GTO. My transmission is failing. It is driveable but when i start making power it slips . I can casually drive it but whats the fun in that . Im looking tonrebuild or replace. It is a street/strip car . Awesome videos wish i saw these back in the day when i was building my car !
Also have a trans cooler cant remember if it 30000 btu or bigger
Give us a call at 888-744-6542 to spec out a rebuild
Great video. A video with all the math? Would be appreciated. This starts to explain the magical converter...
That is all the math any customer needs to figure a stall speed out? The numbers will vary with your setup. That is a sample scenerio only. Once the baseline through this equation is figured you have to use experience as there is no dead set scenerio or first try math. It doesnt exist.
@@PerformaBuiltTransmissions K is the math...how does one factor in weight, gearing, tires, etc. Is it all experience? For us normal Joe's, we'd like to get close based on all the factors you discussed.
BTW, This was a phenomenal video and the only one I've found that discusses all the factors.
Yes experience and its covered. Weight ties in when i mentioned rolling resistance in torque converter operation in the beginning and near end. Ratio is also going to come into play on how effective the vehicle reaches its stall speed from a stop into the powerband. I understand they are subtly mentioned and its alot of information. Thank you very much though! I will be doing a gearing video on final drives so i can be more indepth with it then for everyone
@PerformaBuiltTransmissions I was also wondering how you got K in the equation. You just stated that K is 3000 rpm but I don't understand how you got there. To someone like me who is trying to learn it just doesn't really make sense and feels like I'm coming in halfway through the equation.
@@PerformaBuiltTransmissions Torque converters are the last of the magical boxes. Us normals don't have the resources to pick, try, re-purchase. Not to mention the labor, garage space, tools to do this every weekend till we can get it right. Catching up on your videos .
So what is the actual on paper formula,can you give us that?
Its called the Kfactor and its at 21:30 spelled out right there in black and white
Man I believe that my set up is all wrong from tire size to rear gears and stall
Could I call you to get some info maybe you can give me some input on what I am doing wrong ..?
Simple. Build your car for 1 purpose and not everything. Its all about optimizing what your building it for. If you want the car to do street and strip then the car isnt going to be optimal for either one and might not feel the greatest.
I literally only want to do major burnouts on big rims is it possible to much stall
Can keep me from doing a burnout …??
@@flawlessfades5044 yes because higher stalls are for drag racing to maximize power down the track. Street/ burnout stalls are much lower to give more bottom end torque. You should still be able to do a burnout with a higher stall spd unless your stall is completely wrong for your setup or you dont have enough power / bad technique to do a burnout.
⚡️👍🏼
Could’ve done whole thing in 5 minutes. What he needs is another Tattoo
Got another couple planned. Its so cool you can do it in 5 minutes, me too !
Lol
4000 rpm at 1800 lbs had me laughing hard i would have asked him are you planning on running a 5th wheel and 53' trailer or you just want to be able to cook sandwich's while your in between trips LOL. street and strip guys that like to win have a set of wheels and converter for the street and a set for the strip i have a 71 skylark it takes me 1.5 hrs to swap a converter its a 3000 lb car and i care about my engine Buick's are expensive engines so i keep my rpm and engine load as low as possible on the street my trans runs 180 max even doing burnouts and even with the bigger wheels i only go up 600-800 rpm on stall. NOS is what comes out of my butt after eating empanadas LOL.
Just letting you know gary robinson is cause deformation of character for ypur company. I can twll by what the disassembly he put in his video that someone had been in it since it was purchased from you. His names gary robinson take a look.
Weight. Torque and gearing
Exactly!
Lotta armchair haters in comments with zero videos of their own…
"Chop chop" ?
Big Cam Slang
Dam man! We know we don't know get to the point
Cool fact, There is little line at the bottom of the video you can use to skip ahead to watch the math and calculations.
Blah blah blah wrap it up. I'm starting to forget the important s#!÷ that I thought I learned?
Maybe work on that attention span...
@@PerformaBuiltTransmissions lol
Mild Cam? What a joke. Use the proper 1/4 race, 1/2 race and 3/4 race cam
Everyone knows cams are measured in stages. Lol, them stage 3 cams.
😂😂😂
Write a script and straighten your hat. Until then, you wont be taken serious. Lots of good info, poor presentation.
I get one guy like you every month or so. Ill stick with what the masses say. My reputation is anything but not serious lmao. Check us out literally everywhere
@@PerformaBuiltTransmissions ….. the masses say straighten your hat and write a script, look at any successful motorhead on CZcams. They’ve all got one thing in common, the presentation of their knowledge, theres no stumbling over words or drunk fratboy hats. If 17k is satisfactory, carry on. If ya want more, clean yourself up a bit. Good info, poor presentation. You could be up there with Stacy David(361k subs ie masses). Nothin but love bud.
Didnt start this to get rich or famous. I have a good life and a good buisness and thats enough. I refuse to be corporate and fake like the rest that dont tell it how it really is. The "professional" look never meant anyone is really a professional... and that is reflecting in the transmission world especially today. I say that with love as well. The purpose of this youtube is to teach and bring awareness as well as make my job a little easier and that is purely all. I find it fun and enjoyable by no means will my youtube ever be monotized or made into a career. I may get older but i promise i will never change and i know the way this industry is going down the tubes lately... you all may find you really appreciate how ive been all this time in the very near future.
Good to see you back on utube
