My crate engine manufacturer stated OEM to 1800. 302 HO style block. 367 hp at 5700 rpms, and 356 torque. Car is about 3400 lbs +/-. I've got a TCI which was 1700-1900 stall, and it feels like driving a manual car with a burnt up clutch. Car will not start moving until 1500-2000 rpm from a stop. It always feels like it's slipping. Rear axle is a TOTALLY redone 8 inch with posi, 31 spline axles, aluminum pinion support, nodular case and 3:25 gears. Trans builder checked out the transmission and says all is well, and the convertor HE bought for me feels too high. He builds racing transmissions and years of experience, so I figured he would know. I am about to pull my transmission and install a stock stall convertor and stock style flexplate. The SFI rated plate is too thick for the studs on the stock convertor, so it has to go.

[@jcasey460]

Can you confirm that your example at time 2:19 was miss stated or the info about how the weight of the vehicle affect the selection of the stall speed was incorrect. Lighter vehicles would require lower stall speeds not higher. Thanks

Nice video. Great information. I have a 1994 Ford e-250 5.8 with a E4OD transmission. The rear end differential was replaced and it has a different gear ratio than the original. I believe it has 3:73 wheeas the original was 4:10. The engine is stock no upgrades. Does anyone know what torque converter it would require? I carry close to 900 pounds daily. Also, I went to the dealership to inquire about a replacement transmission, and the man said there are two to choose from depending on the rear end gear ratio, Thank you.

I have a 2012 Chevy Express passenger van it's a 5.3 1LT AWD it has 250000 mostly Highway miles. The trans works great, the engine Burns zero oil and consumes no coolant. I'm getting the code PO700 and p0741. Shortly after these codes appeared the van began to accelerate strangely. It did this when I first accelerated and right around 45mpr. it would lose power but then gained it again, it would do this several times before going back to its normal performance. I noticed that my RPMs would go down and then quickly up and down again while it was happening. I know this is all a Telltale sign that it's the torque converter. However there is something else happening that is strange. First when this was happening I turned on my tow/ haul button and all symptoms would go away. The fault codes would go away but then always come back as my vans computer system would run its Diagnostics . For the last two weeks I've been driving my van with the tow/haul button off and the van is performing normally, however the fault codes continue to turn off and on. I have had the torque converter checked by a professional transmission shop and they found that the slippage is minor, in fact they said and I have verified that my type of clutch converter is designed to slip a little bit. They recommend a whole new transmission but I know that it could be other things like a solenoid or the computer. The van is currently running perfectly it has no symptoms.

[@mikerobertson1781]

Sorry, I didn't get the point at 2:13 - 2:23. You say the lighter the vehicle the lower the stall speed will end up being but you then go on to say your should go to a higher stall speed if you have a light vehicle. Probably my dumb but I don't get this part.

[@gmc4150]

Thanks for the tips What is the proper fluid cooling for a transmission cooler ?

[@SummitRacing]

Hi, Many transmission coolers are rated by BTU (British Thermal Unit) A good operating temperature of an automatic transmission is 160º to 200º F as the fluid exits the cooler. If you can maintain fluid temperature below 175º F the fluid should last for as much as 100,000 miles. Higher fluid temperatures drastically reduces the life of the fluid. Cooler temperature equals longer fluid life. Please see the following link for more helpful tech information from B&M.

[@whitef250powerstroke]

Need more information, but most. modern electronic transmissions have to be reprogrammed anytime a solenoid pack is replaced.

[@SummitRacing]

Hi Juan, We would suggest to check the transmission fluid level (This is done with the engine running, the transmission in Park, and the transmission at a warm temperature), also verify the shift cable is adjusted properly, and lastly you may want to check that the installation of the valve body and solenoids was performed correctly.

[@SummitRacing]

Hi Earl, Anytime you are adding excessive load from a power adder or dealing with issues that would arise relating to the extreme heat, as in turbo applications with long spooling times at the track, you should consider a converter equipped with an anti-balloon plate, billet front cover, and piston along with hardened internal parts like FTI Performance SRL or SRL-3 Series Billet Lockup Torque Converters.

[@boomerspeed0124]

My car is acting like it might have a failing torque converter. Slips a lot when engine and trans are cold, meaning the more throttle is put in the rpms keep going higher than they would if it was gripping properly. The car also loses the majority of its power under 3k rpm, and feels slightly underpowered in the higher rpms as well. VQ engine cars upon cold starts usually idle pretty high, and this car isn't doing it anymore... so I'm not sure if its something with the engine or the transmission. I have a feeling it's the torque converter but I'm not entirely sure.

[@SummitRacing]

There are a lot of variables at play, but it doesn't sound like a converter issue to me. If it is slipping when it is cold, then doesn't when it is warm, sounds like a bad band in the transmission or something else internal in the transmission. The issue of not idling the same sounds like it is engine related.

[@maximuswedgie5149]

Great video! I’m having some issues with knowing cam and horsepower first. I have a basic stock 451 Stroker with 4:10 gears. I purchased a 3200 stall. It was WONDERFUL for 3 days. Now I don’t have 2nd or 3rd gear. Had to drive home in low. Pulling everything out this weekend and sending trans back to rebuild shop. The car drove fine but different. I kept in low gear in neighborhoods, only launched it once hard. That was it. Not sure where or why I have failure. I machined down the flex plate bolts, was very careful followed careful instructions but still had problem. Wondering if my gear ratio is wrong? Any info would be much appreciated, thanks

[@SummitRacing]

Hi, thank you for the compliments on our video. It does sound like something in the transmission failed, but we would not expect the gear ratio or the torque converter to be directly related to the failure. To determine the correct gear ratio you will need to factor in the height of your rear tires. Here is a link to help calculate the correct gear ratio for the MPH and RPM desired in the final drive gear. www.summitracing.com/newsandevents/calcsandtools/gear-ratio-calculator We hope this helps.

[@johnreynolds6291]

Will a worn out Torque converter cause a 4L60E Transmission to slip at 70 mph?

[@SummitRacing]

Hello John, At that speed, your converter should be in lock-up mode unless you're under heavy load or acceleration. Typically, a converter clutch will shutter if it is slipping. A bad lock-up solenoid or debris in the valve body can cause engagement problems as well. I would suggest inspecting your fluid closely for signs of overheating or contamination. The first approach may be a flush and a new filer service. Additionally, there are additives on the market to help with clutch conditioning. www.summitracing.com/search/part-type/transmission-fluid-additives?ibanner=SREPD4

[@blessedperson3676]

Good day. Can a bad torque converter cause a grinding sound when in reverse gear.

[@SummitRacing]

Hi, The torque converter is bolted to the engine and is always rotating in the same direction of the engine at engine speed no matter what gear the transmission is in. Usually if there is an issue with the torque converter, it will affect all of the gears and not just reverse. It seems like the grinding issue is either internally in your transmission or possibly something in your drive line. You may want to raise the vehicle off of the ground, with the vehicle safely supported, put it in reverse and listen underneath to locate the source of the noise.

[@SummitRacing]

Please make sure you installed the torque converter into the transmission first, then bolt the Transmission to the engine and lastly bolt the torque converter to the flex plate. You may want to carefully inspect the front pump of your transmission, hopefully nothing was damaged when the Engine was stuck.

[@chrisrodgers6913]

What's the difference between an oldsmobile and chevy converter

[@SummitRacing]

The attachment to the flexplate is the difference. The Oldsmobile torque converter uses bolts that thread directly into the mounting pads while a Chevy torque converter uses nuts and bolts through its brackets.

[@stevey306]

Not alot they both pure scrap

[@merob3191]

What’s wrong if torque converter never clunks into place but seats all the way?

[@SummitRacing]

The "clunk" is the sound a converter usually makes as it completes its final seating into the transmission pump but may not always be easily detected. Continuously monitor the converter as you are bolting up a transmission, making sure it freely spins as the transmission is drawn up to the engine. If the converter binds, stop and recheck the converter engagement. Damage can occur to a pump if the converter is not seated all the way and the transmission bolted up all the way. If the converter's correctly installed, there should be a small amount of in-and-out play between the converter and the flexplate with the transmission bolted up.
